Integrity Series KNHX38 NEMA 4/4XAir-to-Air Panel-Mounted Heat Exchangers

The Integrity Series KNHX38 is a NEMA 4/4X rated air-to-air panel-mounted heat exchanger designed to deliver closed-loop, near-ambient cooling for electronic enclosures in demanding industrial environments. This unit maintains its sealed NEMA 4/4X rating through fully gasketed flanges that ensure tight, leakproof installation in compliance with UL50 standards, protecting sensitive internal components from moisture, dust, and contaminants.

The heat exchanger features an epoxy-coated aluminum element that provides efficient thermal transfer while resisting corrosion from exposure to moisture and atmospheric contamination. The stainless steel shell construction offers superior durability in hostile environments where chemical and moisture combinations pose a threat to standard materials, making this unit ideal for food processing plants, chemical facilities, coastal installations, and other corrosive settings. Multi-layer corrugated aluminum filters with sturdy one-piece aluminum frames are included to keep internal components clean by capturing airborne particles at the intake point. Replacement filters are readily available through kooltronic.com/spareparts for convenient maintenance and extended equipment life.

The KNHX38 carries full UL/CUL Listed certification, providing assurance of safety and performance compliance for critical cooling applications. Its integrated design and sealed construction eliminate the need for field modifications, enabling straightforward installation while maintaining environmental protection standards.
