Hoffman Thermal Audit

Hoffman Thermal Audit

** RECEIVE A NO-COST HOFFMAN THERMAL AUDIT **

As your local Hoffman representative, I-Pro will perform a thermal audit of your application to assess your cooling needs, reveal cooling deficiencies that can damage electronics, and offer tailored solutions to your cooling challenges.

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
  • Indoor or outdoor
• Maintenance and frequency of access requirements

Key Details We Obtain:

• Indoor or outdoor use
• Air conditioner location on enclosure—side, top or inside
• Dimensions where the air conditioner will be mounted
• Amount of heat energy the A/C needs to remove (heat load)
• Maximum desired electronics temperature inside enclosure
• Type of power source—115 VAC, 230 VAC, other
• Potential application challenges—dust, corrosive air, ocean air, high-pressure water spray, wind-driven rain, sunlight exposure, etc.
• Insulation/no insulation in the cabinet
• Enclosure color (RAL or ANSI spec)
• Remote access considerations (Protocol needed, EthernetIP etc.)

Basic Cooling Principles:

Keeping your electronics cool is essential to maximizing the life cycles of your electronic devices, reducing capital expenses, and keeping your business running.  With expanding deployment of smaller, more powerful, and more portable mission-critical electronics into increasingly harsh environments and conditions, cooling and thermal management is now a primary engineering consideration. 

Sources of Damaging Heat

Heat can be 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

• AC power supplies Controllers, drives and servos
• Transformers and rectifiers
• Processors and server racks
• Radio equipment

Heat is also generated from sources outside the enclosure such as

• Solar heat gain
• High ambient temperature
• Welding processes
• Paint oven
• Blast furnace
• Foundry equipment

Air conditioning (cooling) electronics differs from air conditioning for human comfort
