Noren Drop-In and Flush-Mount heat exchangers are available in UL Type 12, 3R, 4, and 4X. The UL Type depends on many factors. We recommend talking to one of our Territory Account Managers in order to find the best unit(s) for your application.
Noren Drop-In heat exchangers are designed to attach to the top of electrical enclosures. The unit occupies space both inside and outside of the enclosure. They work by transferring waste heat through a specially designed heat pipe core to the ambient air outside of the enclosure. This enables the heat exchanger to lower the internal temperature of the enclosure, while also keeping an air tight seal.
Flush Mount Units
Noren Flush-Mount heat exchangers are designed to attach to the side or door of electrical enclosures. Unlike the Drop-In units, the Flush Mount units do not protrude into the enclosure. They work by transferring waste heat through a specially designed heat pipe core to the ambient air outside of the enclosure. This enables the heat exchanger to lower the internal temperature of the enclosure, while also keeping an air tight seal.
Noren heat exchangers designed for hazardous locations are the only heat exchangers available in the ATEX/IECEx certification standard.
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
Not every application requires a UL certified unit. For these applications we have many heat exchangers that don’t meet any of the UL standards, but they still do an excellent job of removing waste heat from electrical enclosures.
