The process of heat exchange is simple: air temperatures within an enclosure are modified by actions from the outside.
Air/water heat exchange is simple, effective, and efficient. With the aid of cooling water, the air inside an enclosure can be cooled to below the level of the ambient temperature.
Air/air heat exchangers are for environments where ambient air temperature is at or below the desires interior temperature of the enclosure.
As closed systems, no external dust or contaminants penetrate the enclosure. The liquid cooling system may be connected directly to an independent circuit or a facility system. Either system can be mounted on an enclosure's roof or walls using the same mounting cutouts for cooling units and heat exchangers.
Benefits:
Up to 30% slimmer wall-mounted units reduce space requirements
From 3000 to 5000 watts useful cooling capacity
Filters available for a variety of installation environments
Digital controls for thermostats
Fast installation thanks to identical mounting cut-outs for cooling units, air/air heat exchangers and air/water heat exchangers
Air-to-Water Heat Exchangers
Highlights:
Controllers can track temperature control, leak detection, fault signal contact
Closed loop design protects against outside contaminants
Can be mounted on enclosure wall or roof
Corrosion resistant, as air/water heat exchangers are available with stainless steel water-carrying parts

Both of these air/air heat exchangers are particularly well-suited to aggressive ambient conditions, because the internal and external air circuits are completely separate from one another.
Power-Flo Technologies is proud to support Rittal as they create products and solutions that are standardised, customised, and of the very best quality. Rittal's heat exchangers offer a straightforward yet highly effective method for regulating temperatures within enclosures, whether through air-to-air or air-to-water systems. The closed-loop designs prevent external contaminants from entering, ensuring clean and efficient operation. These heat exchangers provide reliable, space-saving, and efficient temperature control solutions, making them indispensable in maintaining optimal operating conditions for sensitive equipment.
