Panel Cooling with Panel Enclosure Coolers

Using our extremely low-cost, reliable Vortex Tube, these Panel Enclosure Coolers will purge AND cool electronic/electrical enclosures with filtered air that's up to 45°F colder than the compressed air supply. Built into the cooler is a relief valve that exhausts the hot air from the cabinet, while the cooler continues to supply clean cold air. Our Panel Enclosure Coolers are ideal for all NEMA 4/4X (IP56) and NEMA 12 (IP52) rated panels. They mount in minutes through a standard knockout.

How to determine size requirements of the Panel Enclosure Cooler
1. Determine the watts of heat generated inside the enclosure.
[ Watts x 3.41 = (W) Btu/hr.]

2. Determine the area in square feetthat is exposed to the air, not including the top of the cabinet.
[ 2 x {Width} + 2 x {Depth} ] {Height} = (S) Square feet of cabinet

3. Determine the temperature difference between the desired internal temperature and the maximum expected external temperature. Now you can use the below chart to determine the Btu/hr./sq. ft., for this differential (B).

4. Determine the external heat load (H).
[(S) x (W) = (H) Btu/hr.]

5. Now take (W) and add (H) to get the total heat load or Btu/hr. refrigeration required to maintain desired temperature and choose the correct one using the chart.
