Integrity Series KNHX59 NEMA 4/4XAir-to-Air Panel-Mounted Heat Exchangers

The Integrity Series KNHX59 is a NEMA 4/4X-rated air-to-air panel-mounted heat exchanger designed to deliver closed-loop, near-ambient cooling for electronics enclosures in demanding industrial environments. This unit maintains its NEMA 4 and 4X ratings through fully gasketed construction that ensures tight, leakproof installation in compliance with UL50 standards, making it ideal for facilities where moisture ingress and environmental contamination must be strictly controlled.

The KNHX59 features a stainless steel shell that provides exceptional corrosion resistance, particularly valuable in applications exposed to chemical fumes, high humidity, or other hostile conditions where standard materials would degrade. The epoxy-coated aluminum heat exchange element combines durability with efficient thermal transfer, while the integrated multi-layer corrugated aluminum filter grid captures particulates and contaminants before they can damage sensitive electronics. The filter is securely mounted in a one-piece aluminum frame for reliable performance, and replacement filters are readily available through Kooltronic's online spare parts catalog.

The Integrity Series KNHX59 carries full UL/CUL listing, providing certification confidence for regulated industries and OEM applications. Its robust construction and sealed design make it well-suited for washdown environments, coastal facilities, manufacturing plants with airborne contaminants, and any application where equipment protection and reliability are paramount.
