Hoffman Thermal Audits Provide Solutions to Cool Electronics and Maximize Equipment Life

Hoffman thermal audit maximizes equipment life

Summer’s coming, and the time to begin protecting your electronics, before it’s too late, is today. As temperatures rise, industrial electronics can overheat, causing malfunction and even complete device failure. In fact, statistics show that for every 18°F over room temperature, the life expectancy of an electronic device drops by 50%.

To determine thermal heat loads, and examine the stress placed on electrical devices by excess heat, Steiner is offering a FREE THERMAL AUDIT to be conducted by its Hoffman-trained and certified expert.

A thermal audit can identify problem areas and produce compelling evidence of excess heat that can affect performance and potentially damage critical equipment.

Are Your Electronics in Danger?

Keeping electronics cool is essential to maximizing the life cycle of electronic devices, reducing mean time between failures (MTBF), cutting capital expenses, and keeping production humming along.

Heat is generated internally by electronic components and intensified by external sources. Inside a cabinet, uncooled components can generate as much trapped heat as a home furnace.

Heat sources include:

  • AC power supplies
  • Controllers, drives and servos
  • Transformers and rectifiers
  • Processors and server racks
  • Radio equipment
Thermal energy from an electrical enclosure is measured during a thermal audit.

To cool the electronic and its components, the thermal energy must be transferred away from the device. There are a few basic ways to cool industrial enclosures, including using a sealed enclosure that utilizes a heat exchanger, an A/C unit that uses a fan to circulate fresh air through a cabinet, or via conductive cooling in which the heat radiates through the cabinet.

Without these measures, temperature variations can lead to everything from nuisance problems to shutdowns. Tripping can become a source of frustration, and heat stress can affect loop controllers, PLCs and more.

At high temperatures, drive performance can be derated, and I/C-based devices can behave strangely creating unusual output such as voltage fluctuation. At low temperatures, cooling below the dew point can lead to condensation and promote corrosion.

For instance, MOSFET transistors, which are voltage-controlled field effect transistors made from metal oxide and silicon components, can falter from excess heat. High temperatures can change the properties of the silicon oxide. The higher the temperature, the higher the threshold voltage that triggers an open gate. At too high of a temperature, the gate may not open at all.

Another potential heat-related hazard pertains to wiring insulation. With increasing temperatures, elasticity and strength of the insulation are reduced, and ductility can temporarily increase.

What is Tested During an Audit

When a facility is audited, the inspector looks at all the factors that could affect temperature increase. Typically, a Hoffman thermal audit examines:

  • Heat load of enclosed electrical equipment
  • Temperature ratings of the installed equipment (upper and lower limits)
  • Ambient temperature (typical and extreme)
  • Environmental conditions
    – Clean air (Type 1)
    – Dirty or wet environment (Type 12, Type 4/4X)
    – Closed- or open-loop cooling systems
    – Indoor or outdoor enclosure location
  • Maintenance and frequency of access requirements

When finished, a report is developed that will provide recommended thermal management solutions. These best practices are designed to keep electronic components cool and help minimize unplanned failures.

A thermal audit helps determine best practices for managing thermal energy.

Essentially, by removing the waste heat, efficiency can be increased while downtime and operating costs are reduced.

Allowing electronic components to run hot can be a gamble that could require a company to prematurely replace industrial drives, cause hours of automation system downtime, and create out-of-warranty conditions when cooling is not used.

Schneider Electric Provides Safety Switches For Infinite Applications

Schneider’s Square D Safety switches are vital components to safety and power control. They are a means to disconnect from the electrical load and provide protection to the branch circuit.

When necessary, they can be used to disconnect manufacturing equipment, heavy machinery and light commercial and residential applications from its power source. Users may need to disconnect equipment from its electrical supply for a variety of reasons from scheduled preventive maintenance to emergency stoppage.

The performance of safety switches is important to the safe operation of many industrial applications. In addition, requirements from a variety of organizations  have increased the use of safety switches in many commercial and industrial facilities.

In addition, safety switches are an NEC requirement in industrial and manufacturing facilities.  For instance, a safety switch must be in sight from all motors or manufacturing equipment and not more than 50 feet from the equipment it controls.

A key performance benefit of the Schneider safety switch is its ability to break load. A locked motor can draw six to eight times motor full-load current. In an emergency situation, it’s important to have a safety switch with enhanced load-break features such as those featured in Schneider’s switches. A key element of Square D safety switches is its blade and jaw construction that has been designed to manage heavy motor loads and arc interruptions.

Multiple types of disconnect switches are available, and the switch that work for you depends on a number of factors in your working environment.  Steiner’s expertise can help make the appropriate choice. Steiner stocks a large inventory of safety switches ready for pickup at one of our convenient locations or on-time delivery to your facility or job site, including: general duty, heavy duty and double throw switches in single and multiple pole, fusible and non-fusible.

Here is a look at some of the most common safety switches.

General Duty Safety Switch
Schneider Electric Square D General Duty Safety Switch
General Duty Safety Switch

One of the most go-to safety switches are those that are considered General Duty (GD) safety switches. These are designed for residential and commercial applications and where durability and economy are prime considerations. Typical loads are lighting, air conditioning, and appliances. They are suitable for use as service equipment when equipped with a factory or field-installed neutral assembly or a field-installed service grounding kit as applicable.

  • Voltage: Maximum voltage of 240 V
  • Current Rating: Max amperage of 800 A
  • Enclosure: Available in Type 1 and Type 3R enclosures
  • Certification: UL Listed, File E2875
  • Standard: Meets or exceeds the NEMA Standard KS1
Heavy Duty Safety Switch
Schneider Electric Square D Heavy Duty Safety Switch
Heavy Duty Safety Switch

Visible blade heavy duty safety switches are designed for applications where maximum performance and continuity of service are required. All heavy duty safety switches feature a quick-make, quick-break operating mechanism, a dual-cover interlock and a color-coded indicator handle.

  • Voltage: Maximum voltage of 600 V (ac/dc)
  • Current Rating: Max amperage of 1200 A
  • Enclosure: Available in Type 1, Type 3R, Type 4, Type 4X, Type 5, Type 7, Type 9, Type 12 and Type 12K enclosures
Double Throw Safety Switch
Schneider Electric Square D Double Throw Safety Switch
Double Throw Safety Switch

Double throw safety switches are designed for manual transfer of one load between two power sources. The units are tough and reliable to provide emergency back-up power connections in accordance with Article 702 of the National Electrical Code, ANSI/NFPA 70.

  • Voltage: Maximum voltage of 600 V (ac/dc)
  • Current Rating: Max amperage of 600 A
  • Enclosure: Available in Type 1, Type 3R, Type 4, Type 4X, Type 5 and Type 12 enclosures
Make Selections EZ

These safety-switch options, and others that are more specific in application, come with multiple options such as various difference in amperage and voltage. In some cases, the question is whether to use fusible or non-fusible switches.  Fusible safety switches combine fuses with the switch in a single enclosure. For both fusible and non-fusible safety switches, when the circuit is open, the safety switch disconnects the load from its source of power, while closing the circuit reconnects the load.

The Schneider Electric Safety Switch EZ Selector can guide you to the most appropriate safety switch for your required application.
The Safety Switch EZ Selector can guide you to the most appropriate safety switch for your required application.

With all the product variables from application to enclosure type, voltage to amperage applications, selecting the appropriate safety switch can be a challenge. Schneider Electric has made the process simpler by developing the EZ Selector system.

The EZ Selector tools ask simple “click-to-answer questions,” and the user is self-guided through a process that ultimately leads to the right product for the application.

Sandvik CoroMill 390 is One Tool for Many Applications

From general milling of standard metals to milling complex deep pockets for producing aerospace components out of modern metal materials, Sandvik’s CoroMill 390 is a versatile cutting tool with broad functionality.

SandVil CoroMill 390 can be used for general milling and complex projects with challenging materials.
Sandvik’s CoroMill 390 can be used for general milling and complex projects with challenging materials.

Sandvik’s “390” cutter family can be used for myriad applications by integrating a large, versatile program, including versions for shoulder milling and long-edge milling. Cutter inserts generate a good, quality 90-degree shoulder and are ideal for ramping and helical interpolation.

For instance, to produce precise contours without steps in repeated shoulder milling operations, the company offers close-tolerance inserts and an exact insert position. The smooth cutting action of CoroMill 390 limits radial cutting forces, which minimizes bending and generates good wall perpendicularity.

CoroMill 390 insert size 07
CoroMill 390 insert size 07.

The CoroMill 390 assortment of inserts includes cutters with size 07 inserts in dimensions specifically designed for key slots. With a tool diameter that is 0.3 mm (0.012 in.) smaller than the slot width, a suitable amount of stock is left for the subsequent finishing operations.

In another example, using helical interpolation and linear ramping to create holes from a solid workpiece requires a strong insert face geometry. The CoroMill 390 inserts are developed to withstand the stress caused by steep ramping or demanding interpolation, giving a low-vibration process with even tool life.

Plunge milling using the CoroMill 390 produces less stress on your machine spindle because of its vibration damping attributes. Because of this, it is suitable for unstable machines, deep slots, difficult-to-machine areas, and high-radial engagements such as corners.

Incorporating new steel grade
CoroMill 390 covers many applications with a large, versatile program.
The CoroMill 390 can be used for many applications because of its large, versatile tool program.

CoroMill 390 is made with Sandvik’s robust steel milling grade GC1130, which is made with the Zertivo PVD coating process that reliably performs even in unstable or challenging conditions such as disparate temperature variations.

The Zertivo process includes a complex set of steps, including pumping, heating, etching, coating, and cooling. Process parameters such as temperature, gas flow, and pressure are crucial to the final tool performance.  Each grade is produced with the exact right conditions for that specific grade. The result is improved adhesion between substrate and coating as well as optimized cutting-edge integrity.

The result is great edge-line security and reduced flaking. This makes the insert resistant to chipping.

In addition, the tool’s high-Cr (Chromium) content, in its fine-grain substrate, is optimized to withstand edge-line chipping and cracks arising from difficult machining and demanding conditions, such as temperature variations.

Keep Silent

Some of the tools incorporate the company’s Silent Tools™ technology. Sandvik Coromant’s endmill for small diameters, for instance, available with size 07 inserts, is a versatile cutter ideal for shoulder milling, deep shoulder milling, edging, linear and helical ramping, plunge milling, slot milling and face milling.

Insert sizes 07 and 11 are available with Sandvik’s Silent Tools™ damping technology. The upgraded Silent Tools dampening technology will allow machine shops to machine deep pockets for products such as titanium aerospace frame parts.

Silent Tools™ CoroMill® 390 cutters
Silent Tools™ CoroMill® 390 cutters.

Silent Tools provide light-cutting insert geometries and high-performance grades that deliver low-cutting forces and vibration-free machining for secure, cost-effective milling. The tool holders are designed to minimize vibrations through a dampener inside the tool body.

The CoroMill 390 Silent Tools can be ordered in diameters from 20 to 32 mm. It is available for both the new insert size 07, as well as insert size 11, with options for either cylindrical shank or Coromant Capto coupling.

Challenges and solutions

Sandvik Coromant calls the CoroMill 390 a “go-to cutter.” As evidence of this, Sandvik has detailed some typical challenges and its solutions.

For instance, pocket milling can be challenging to produce efficient and secure cavity opening. Using helical interpolation and linear ramping to create holes from a solid work piece requires strong insert face geometry. CoroMill 390 inserts are developed to withstand the stress caused by steep ramping or demanding interpolation, providing a low-vibration process with even tool life.

Here is a look at some other challenges:

Process: Slot milling
Challenge: Chip evacuation and vibration.
Solution: Insert geometries designed for ideal chip formation and evacuation. When milling with large engagements, vibration often causes rapid tool wear. The light cutting inserts of CoroMill 390, combined with cutters with optimized differential pitch, offer a low-vibration milling process.

Process: Face milling/Key Slot Milling
Challenge: Metal removal rate and surface finish.
Solution: Durable CoroMill 390 inserts are capable of high cutting parameters. -L geometries designed for milling with low cutting forces are perfect for facing surfaces with a shiny finish and close tolerances.

While there learn about the variety of Hubbell product SKUs and mass inventory of floor boxes, fire-rated poke-throughs, covers, electrical outlets, HDMI ports, USB plugs, RJ jacks, and other options that make up Steiner FLOOR BOX CENTRAL.

Central to Hubbell’s products is their compatibility. They are designed to work in tandem, including the SystemOne line, and that compatibility lets architects, designers, contractors, owners and all of those in the design chain create an aesthetic that remains constant from the first floor to the penthouse.

This provides Steiner’s customers with many choices. Hubbell’s concept is the antithesis of Henry Ford’s famous quip that customers could have their cars in any color they wanted, as long as the color was black. That would not cut it in today’s marketplace.  Consumers want choices. That is true of a car and everything else, even devices as tried-and-true as a floor box.

Hubbell’s SystemOne floor box line is now available for concrete, raised access and wood floor applications.

Hubbell provides its range of multi-gang floor box products in various shapes and sizes and in a variety of colors and finishes. If you want a floor box with a rectangular or round cover with nickel coating that goes into a concrete floor, Steiner FLOOR BOX CENTRAL has it. PLUS, we can supply matching poke-throughs with a 8-in. nickel-plated round cover that can be used in wood, tile, and carpet covered floors.

SystemOne Features

Hubbell’s SystemOne floor box line has many features, including:

Kohler Natural Gas Generators More Efficient than Ever

Get peak performance from natural gas generators

While diesel has been the conventional fuel of choice for backup generator sets because of its initial capital cost advantages, things are changing as regulations, costs and technologies have evolved, and, because of that evolution, natural gas generators have gained in popularity.

“Over the past 15 years, there have been numerous performance developments in gas generator set technology to improve fuel efficiency, reduce exhaust NOx emissions and increase ratings,” according to Clay Hardenburger, senior staff applications engineer for Kohler Co. Hardenburger is the author of a new whitepaper, Gas Generator Set Performance Characteristics, that takes an in-depth look at characteristics of natural gas powered generators, the fuel used, their applications, and more. (To get a copy of the free whitepaper, click here.)

Kohler's standby commercial generators can run on propane or natural gas.
Kohler’s standby commercial generators can run on propane or natural gas.

“These key development characteristics combined with incentives to develop renewable energy biogas fuel sources have moved the industry forward to consider gas generator sets as the preferred electrical power generation technology for continuous duty applications when paralleled with the utility,” writes Hardenburger. “In addition, recent expansion of natural gas fuel sources in the United States has resulted in low fuel prices, which is also driving the marketplace to utilize gas generator sets for standby and prime applications typically served by diesel generator sets.”

Kohler Co.’s Power Division offers a slew of EPA emissions-certified LP and natural gas generators in the up to 400 kW range, delivering an installation-ready product for residential power and light commercial applications. Kohler also developed a new line of large natural gas generators that are designed specifically for standby, prime or continuous power applications in the North American market. The large gas gen sets range from 425 kW to 1300 kW (and growing). For applications that require larger industrial generator sets, contact Steiner’s Power Systems division experts and they can help you choose the most appropriate generator.

These natural gas generators run on relatively clean burning fossil fuels such as propane. The lower emission gaseous gen sets significantly reduce carbon monoxide and particulate emissions.

Get your generator locally from Steiner

Steiner Electric, a local authorized distributor of Kohler products, offers an extensive inventory of residential and commercial generators that primarily operate in standby-rated mode utilizing LP or NG fuel.

Models rated for residential and light commercial applications include the 14/20kW RESA models that feature Kohler’s PowerBoost Technology for improved starting power. The generator can easily start and run a 5-ton air conditioner. The 38/48/60kW RCL model offers quiet operation and the Fast-Response II excitation system that delivers excellent voltage response and short-circuit capability using a permanent magnet alternator.  The 60kW ERESB model for light commercial application, which utilizes NG and LPG gas, and depending on voltage achieves

In addition to Steiner’s large inventory of generators, as a registered, certified distributor of Kohler generators, generator experts are available 24 hours a day, 7 days a week for emergency situations. In addition, all Steiner generator experts undergo rigorous training programs that must first be completed and are routinely updated.

Burn it Lean, Burn it Rich

These models operate differently depending on the fuel used, mixture of air and fuel, applications and other factors. Often, there are tradeoffs such as between power and efficiency.

To help straighten out the web of generator options, and best understand the unique factors of each, Hardenburger’s whitepaper addresses the

The 80/100/125/150 kW ERESD model generator for light commercial applications.
The 80/100/125/150 kW RESD model generator for light commercial applications.

performance characteristics found in gas generator sets that utilize different fuels and engines, power factor, generator set rating, load requirements, and more parameters.

Fuel sources, for instance, typically come in two categories: methane-based fuels sources and hydrocarbon-based fuel sources. As Hardenburger explains, methane-based fuels such as pipeline natural gas are for use in high-compression ratio, lean-burn engines. Hydrocarbon-based fuel sources such as propane can be used in low-compression ratio, rich burn engines.

Hardenburger says that gas engines are classified as either lean-burn or rich-burn combustion types. Each type has its own advantages and disadvantages depending upon the application.

Lean-burn engines are associated with high-electrical efficiencies, and are typically used in continuous parallel with the utility applications as a primary power source because of limited transient response capabilities. Whereas rich-burn engines are usually associated with applications where transient load response is more critical than fuel efficiency. They are typically applied in emergency standby applications where the generator set system is the secondary power source when utility power is not available.

Rich-burn engines are a better choice in applications where large transient load changes above 30% are required. An LPG fuel source can be utilized in these applications without derate if low compression ratio engines are utilized.

Kohler large natural gas generator
Kohler offers natural gas generators at up to 1300 kW. For more information about your application, contact your Steiner Power Systems application engineer at (847) 956-3098.

Lean-burn engines are a better choice in applications where the utility is always present, and the required operational capacity exceeds 8,000 hours per year. Fuel efficiency is a key consideration in continuous applications, so engines with high compression ratios are typically utilized. Heavy hydrocarbon fuels such as LPG cannot be utilized in these applications without significant engine derate.

The newest and smallest of the SINAMICS V20 family of drives are the FSAA and FSAB models that save more than 30% in mounting space compared to the previously smallest model, the SINAMICS’ FSA model (90 mm (3.5 in.) x 150 mm (6 in.)) . With a width of just 68 mm (2.7 in.) and a height of 142 mm (5.6 in.), the AA and AB models both have the same footprint, but different heatsink depths.

The V20 family of rugged devices, which are IP20 rated and can be EMC filtered, are tailored for operating pumps, fans, compressors and conveyor belts as well as for basic drive applications in the process and manufacturing industries.

Ease of use and installation

One of the V20’S benefits is ease of installation. The units can be wall mounted, push through mounted for efficient cooling, and side-by-side mounted to reduce required cabinet space. Typically, drives need to be 2 in. apart for cooling purposes, but with heat sinks located judiciously to release heat through the top and bottom of the unit.

The unit itself is easy to use. A Parameter Loader makes it easy to program and speed up commissioning. This modular, plug-and-play device easily installs to the face of the drive. The device uses a memory card that allows more than 100 parameters to be installed such as motor specifications, voltage, current speed, application deceleration rate acceleration rate and other pertinent data, says Jovan Cetkovic, Motion Specialist with Steiner Electric.

Additionally, “cloning” is possible by installing the same parameter loader on different drives.

Without the parameter loader, users access a basic operator panel on the face of the drive. Utilizing the BOP, all parameters can be programmed giving the user full control of the drive in terms of speed and other factors.

In addition, there are terminals on the face of the drive that allow for direct wiring for analog I/O control.

The SINAMICS’ V20’s feature a Keep Running Mode that keeps the output load running even in the event of power fluctuations, overvoltage, overcurrent, or other power stability issues.

Energy savings is achieved in several ways. For instance, the SINAMICS V20 drive makes it easy to save money through the use of an ECO mode that ensures that the motor current is automatically adapted to the load state. In addition to that, the drive is capable of DC bus couplings such that a drive regenerating can share power with other drives.

The drive also features a Hibernation Mode that reduces energy consumption when the drive is not in active use.

It also features an integrated braking chopper from 7.5 kW to 30 kW (10 hp up to 40 hp). When a motor is de-energized and coming to a stop, it changes from a motor to a generator producing energy. Resistors dissipate energy so the VFD’s capacitors are not damaged. This power can also be used during drive regeneration.

The V20 drive family has a number of accessories that can be used. For instance, a new extension module is available to increase the number of inputs and outputs of the SINAMICS V20 400V converter.

Mounted onto the converter, the module provides 2 additional digital inputs and 2 relay outputs to the converter. The module increases functionality. For example, it can now be used for multi-pump control, where one V20 can control a maximum of four pumps.

Equipped with connection ports on its front- and backside, the module may be used in combination with other accessories of the SINAMICS V20 such as the BOP, the BOP interface, and the Smart Access web server.

Worldwide access
The SINAMICS V20 Smart Access webserver module option is mounted on the converter. It allows wireless commissioning and operation via smartphone, tablet, or laptop.

SINAMICS V20 Smart Access is a tiny drive-mounted web server module that turns a mobile device or laptop into a virtual operator panel, allowing it to commission, operate, diagnose, and maintain the AC drive.

An embedded graphical user interface (GUI) enables easy use of the SINAMICS V20 in every phase of operation.  It requires only a few steps to set-up and no installation or download of additional software is needed.  The onboard Quick Set-up Wizard provides users a fast and easy commissioning procedure, enabling all the following: motor data can be entered and checked, connection macros for digital inputs/outputs can be activated, application macros can be selected and activated for pumps, fans, compressors and other devices plus the common and frequently used parameters on the drive can be set for motor start, acceleration, deceleration, and min./max. speed.
