1. How much power do air to air heat exchanger use?
The heat pipe does not use electricity at all. However, for efficient operation, a small fan is required to circulate air within the electrical enclosure and blow external air over the top of the heat pipe.
2. Can they cool below ambient temperature?
No. The air-to-air heat exchanger's outer casing is always slightly warmer than the surrounding air temperature. The actual differential will depend on the heat load and the capacity of the air to air heat exchanger.
3. Do they require servicing?
The only servicing that’s required is to keep the airways clean. Make sure the fan and air intake is clean and blow away any dirt that has adhered to the heat pipe fins.
4. Are they suitable for use in sealed enclosures?
Yes. An quality air to air heat exchanger is a closed loop cooling system that is only suitable for a sealed enc.
5. Can I put one on my enclosure door?
Yes. as long as the door is strong enough, the outer casing can be properly secured and can support the weight of the air to air heat exchanger without tipping over.
6. Can I use solar energy?
Yes. The only power requirement is the fan, which can be used for AC power and a variety of 24 and 48 VDC.
7. Can I use it in a hazardous location?
Yes. Models are available to meet the requirements of certain hazardous locations.losure. Models are available to suit NEMA 12, 4, and 4X enclosures.
