AIR/WATER HEAT EXCHANGERS
Our PWS 3302 (NEMA Type 12/3R/4) Advantage Series Air/Water Heat Exchangers offer over 12000 Btu/h cooling capacity and are ideal for harsh ambient conditions. Requiring only a cool liquid source and power. Need a cool liquid source? Pair this unit with one of our packaged chillers. Housing: galvanized sheet steel. Cover: electrostatically powder coated RAL 7035 (light grey); for ANSI 61 grey use part no. ending in …251
Washdown Roof Design
Metal covers are designed with a sloped top which sheds water away from the electrical enclosure as well as eliminates potential water pooling, corrosion and ice buildup.
Powder coated steel or stainless steel cover designed for manufacturing environments. Easily painted to match enclosure or machine.
Long Airflow Path
Heat exchangers are designed to draw hot air from the top of the enclosure and deliver cool air below the components.
Closed Loop Design
Designed to isolate the external ambient air from the internal air circuit eliminating the risk of contaminants entering the cabinet.
Push to Connect Fittings
Hydronic connectors that supports quick connection to 1/2 inch O.D. hose or 1/2 inch I.D. hose with included adapter. Unlike other units that have rigid permanent connections.
Optimized Internal Design
Smart engineered solution, easy to service and maintain.
Intelligent Control of Water Flow
The adjustable mechanical thermostat permits precise control of the electrical enclosure temperature by regulating the coolant flow by activating a solenoid valve. This regulates the coolant flow to minimize coolant waste and increase energy-efficiency.
Physical barriers allow for condensation to be collected and drained from the system with zero intrusion into the cabinet.
