Integrity Series KNHX32 NEMA 4/4XAir-to-Air Panel-Mounted Heat Exchangers

The Integrity Series KNHX32 is a NEMA 4/4X-rated air-to-air panel-mounted heat exchanger engineered for closed-loop near-ambient cooling in demanding industrial environments. This robust unit maintains sealed enclosure ratings while delivering efficient thermal management, making it ideal for electronic control systems and sensitive equipment that require protection from external contaminants and harsh operational conditions.

The heat exchanger features a stainless steel shell construction specifically designed for corrosive and hostile environments where chemical and moisture combinations pose a threat to equipment longevity. The epoxy-coated convoluted aluminum cooling element is fabricated to the same exacting standards as uncoated aluminum elements and exceeds 1000 hour salt spray testing requirements, ensuring superior corrosion resistance and extended service life. Fully gasketed flanges throughout the unit maintain the NEMA 4 and 4X enclosure ratings (UL50 certified), providing tight, leakproof installation that protects internal components from water intrusion and environmental contamination.

Kooltronic's multi-layer corrugated aluminum filter system is standard on all units, featuring a sturdy one-piece aluminum frame that captures particulates and keeps internal components clean during operation. Replacement filters are readily available through kooltronic.com/spareparts for convenient maintenance planning. The KNHX32 is UL/CUL Listed, providing full compliance certification for regulated applications and industries where third-party validation is mandatory.
