Heat Exchangers

The Kooltronic line of Heat Exchangers utilizes various heat transfer technologies, making it one of the most versatile product offerings available. By combining powerful forced-convection cooling with the advantages of a closed-loop airflow system, Kooltronic Heat Exchangers satisfy a wide range of enclosure cooling requirements for environments that contain contaminated ambient (outside) air. The adaptability of Kooltronic Heat Exchangers is increased by flexible mounting orientations and a comprehensive line of accessories and options.

Heat Exchangers offer several enclosure cooling benefits including simple reliable performance and operation, low maintenance, and energy efficiency. By comparison, Heat Exchangers provide many of the advantages of enclosure air conditioners but are generally less costly to install and operate - making them an economical and efficient closed-loop cooling option.

Enclosure Heat Exchangers offer closed loop cooling that is economical and efficient

All Kooltronic Heat Exchangers provide a large heat transfer area in a compact package with high performance air systems, providing high flow rates and thorough air distribution. The closed-loop design cools and recirculates the same clean air within the enclosure, isolating components from the hostile environment. All Kooltronic Heat Exchanger elements are manufactured in the USA at our Pennington, NJ facility.

Air-to-Air Heat Exchangers are the ideal choice for applications that can tolerate operating temperatures somewhat higher than ambient. However, if below ambient temperatures are required, we recommend an enclosure air conditioner. Both options can be considered for enclosures located in areas where airborne contaminants pose a threat to the internal electronic components, and the enclosure interior must be isolated from the external environment. Read our blog post, "What is an Air-to-Air Heat Exchanger" for more information about how these enclosure cooling products work.

Most Kooltronic Heat Exchangers are designed for installation in indoor environments. For outdoor operation or applications requiring washdown, Kooltronic offers Integrity NEMA 4/4X Heat Exchangers which feature weather protection and other special protective features.

The KTHE Series features a refrigerant-charged fin-and-tube coil, employing the heat pipe principle. The KXHE, KXNP and KNHX Series utilize a high-efficiency convoluted aluminum heat transfer element. These elements provide excellent thermal transfer performance and are easily removed for cleaning.

Water-to-Air Heat Exchangers, such as the KPHE and KNHE Series, fill the performance gap between Air-to-Air Heat Exchangers and enclosure air conditioners. If a reliable, clean cool water supply is available, these units are often the ideal solution when extreme contaminant or temperature conditions are present. For more details about the operation of water-to-air heat exchangers for electrical cabinets, read our blog post, "What is an Water-to-Air Heat Exchanger".

Most standard Kooltronic Heat Exchangers are UL/CUL Listed and all units feature rugged construction of precision-engineered heavy gauge steel that ensures they will withstand the tough conditions they may encounter.

For a more customized application, we offer a full line of enclosure accessories and options to satisfy your enclosure cooling requirements. Some of these accessories include alarms for both temperature and water supply (water-to-air models), low airflow detection, internal corrosion protection and custom shells, such as stainless steel or aluminum. A wide range of replacement filters are also available from our inventory. Alternatively, if our standard products do not meet your needs, our Engineering staff can custom-design unique heat exchangers to meet your specifications.
