150 Watts/°C
Our PKS 3303 (NEMA 3R/4) Outdoor Air/Air Heat Exchangers are an ideal solution for a wide variety of applications. Closed loop design isolates external air from inside of enclosure without the need to change filter. Housing and Cover: electrostatically powder coated RAL 7035 (light grey)
Features
Best CCPD™
Cooling Capacity Per Density (CCPD™) measures the cooling power per volume size of the unit. The PKS 3303 produces superior CCPD vs. conventional heat exchanger and/or heat pipe solutions. One of the most compact units for the available cooling capacity.
Energy Efficient
Utilizes lower temperature ambient air to cool warmer internal air without an active component such as a compressor which consumes high amounts of energy.
Closed Loop Design
Designed to isolate external ambient air from internal air eliminating the risk of contaminants entering the cabinet. Compared to Filterfans® with Rainhoods; the PKS seals against gaseous substances, humidity and airborne particulates such as dust, keeping it away from sensitive components within the electrical enclosure.
Narrow Width
Width of the unit is maintained at 12 inches to fit onto the side of a smaller NEMA enclosure.
Reduced Maintenance
With only two mechanical components (fans), potential failure point is reduced to ensure continuous uptime of your processes.
Mounting Flexibility
Unit can be installed vertically or horizontally, allowing the cool air to be focused where it is needed most.
Easy Installation
Compact lightweight design means that the unit can be installed by just one person.
Self Protected from Harsh Environments
Uniquely designed to operate in NEMA 3R, 4, and 4X environments. An example of this is the location of our control electronics within our dry, cool interior circuit.
Eliminates Hot Spots
High CFM fan with superior air flow, ideal for eliminating hot spots.
