Below Ambient Cooling Units
From Noren Products
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 including Class I and II, Division 1 and 2 classifications. 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.)
