KNHE28 Water-to-AirPanel-Mounted Heat Exchangers

The KNHE28 is a water-to-air panel-mounted heat exchanger engineered for precision temperature control in demanding industrial environments where protection of sensitive components is critical. Its closed-loop cooling design isolates the interior airflow system from ambient air and external water sources, ensuring that the component compartment remains cool and dehumidified without risk of contamination from outside air or moisture intrusion.

The heat exchanger features epoxy-coated aluminum coils designed to resist corrosive conditions, with a proven coating durability of 1000 hours under ASTM B 117 salt spray testing. For applications in particularly severe environments such as wastewater treatment facilities or areas with heavy salt spray exposure, a stainless steel shell option is available to provide enhanced corrosion resistance, especially where chemical and moisture combinations present ongoing durability concerns. All gasketed flanges are precision-fitted to maintain a tight, leakproof seal in compliance with NEMA 4 and 4X enclosure ratings per UL 50 standards, ensuring reliable performance in wet or washdown environments.

The KNHE28 is UL/CUL Listed for safety and performance assurance. For applications in highly corrosive operational settings, warranty coverage may be affected, and customers are encouraged to consult with the factory regarding available corrosion protection options and specific warranty limitations for their intended environment.
