Cooling:

Chillers:

• Are very sensitive to heat
• Are the most common point of failure/shutdown due to heat
• Must have direct feed of fresh air at the condenser
• NEVER restrict air flow through the unit *at all*
  • If anything, force more flow through it 
• Chillers are also sensitive to bumpy roads during travel
  • For best performance and smoothest ride, position the chiller at the front of the trailer

Air Compressors:

• The second most common point of failure/shutdown due to heat
• Must have direct feed of fresh air at the cooling inlet
• Do not restrict flow too much
  • Depends on internal fan capability 
  • Additional flow may be helpful

Air dryers:

• Generally we don’t see overheating problems
• Keep in mind, the cooler the condenser air, the drier the compressed air will be
  • More dry air = Fewer ozone system maintenance problems

Cabinet Air Conditioners:

• We rarely see overheating problems whenever it is sufficiently oversized
• Ensure there is at least some air movement past and/or space around the cabinet

Air-cooled ozone generators:

• The cooler the air going through the heat sink, the better the ozone production will be
  • Most air-cooled generators can operate and create ozone up to 100F ambient temperature
    • High Temperatures = Lower output performance
    • Cooler Temperatures = Greater output performance
      • Example: 80F often it is sensible to air condition the space or cabinet where the generator is located

Exhaust fans:

• Most effective if positioned directly adjacent to the heat source
• Ensure the exhaust fan isn’t competing with anything else for suction
  • Example: If a compressor is also ducted out, the fan can steal its airflow and starve it
