Below Ambient Cooling Heat Exchangers

Designed to cool overheating electrical panels and enclosures to below the outside ambient air temperature. Easily replaces air conditioners and compressed air coolers.

Heat Exchanger Air to Water Units

UL Certified Heat Exchangers

Noren below ambient cooling heat exchangers are easy to install and maintain.  They have a isoloss gasket that seals against the enclosure and keeps contaminants out. Using our specially designed open loop core, the unit removes waste heat inside the enclosure to below ambient temperature, using only 1GPM water source for most units.  Below ambient cooling units are typically mounted on the side of the enclosure and can be used in series as needed.  With our UL LISTED 12, 4 or 4x units, they lend themselves well to being used in 508a applications.

Hazardous Location Heat Exchangers

Using Noren’s specially designed core, the below ambient heat exchanger removes waste heat from the cabinet and cools the internal air to the temperature of the water circulating through the heat exchanger’s core. These units have no external fans and therefore do not require filter kits.

Custom Design Heat Exchangers

Depending on your unique application, you may need a specially designed heat exchanger. Our engineering team is happy to work with you to design and manufacture a custom unit, or multiple units.

Custom heat exchangers are often based on our standard heat exchangers. The various attributes of the standard unit are then modified or changed in order to meet the needs of the application.

Non UL Certified Heat Exchangers

Using fans suitable for combustible environments, Noren offers ambient cooling and below ambient cooling units for use in hazardous locations. In both purge and non-purge applications where water is available for cooling, our air to water units are the ideal low cost, low maintenance solution. (Unit will not maintain NEMA 7 type enclosures.)
