KNHE20 Water-to-AirPanel-Mounted Heat Exchangers

The KNHE20 is a panel-mounted water-to-air heat exchanger that delivers reliable closed-loop cooling for sensitive electronic components in industrial enclosures. By isolating the interior airflow system from ambient conditions, it ensures that cool, dehumidified air reaches critical components while preventing outside air, moisture, and contaminants from compromising performance or reliability.

Constructed with a stainless steel shell, the KNHE20 is engineered to withstand corrosive and hostile environments where chemical and moisture combinations would degrade standard materials. The unit maintains its NEMA 4/4X rating through a fully gasketed design that creates a tight, leakproof installation, meeting UL50 standards for water- and dust-resistant enclosure protection. This robust construction is especially valuable in industrial settings where environmental challenges would otherwise accelerate corrosion and equipment degradation.

The KNHE20 is UL/CUL Listed, confirming its compliance with stringent safety and performance standards for industrial cooling applications. Its combination of closed-loop isolation, corrosion-resistant materials, and sealed construction makes it an ideal choice for mission-critical installations requiring maximum protection and uptime.
