TrimLine Series KXNP33Air-to-Air Panel-Mounted Heat Exchangers

The TrimLine Series KXNP33 is a panel-mounted air-to-air heat exchanger designed to deliver closed-loop, near-ambient cooling for sensitive electronic enclosures and industrial control equipment. By circulating air between an internal space and the external environment, this unit maintains optimal operating temperatures without introducing contaminants, making it ideal for demanding applications where equipment reliability is critical.

The heat exchanger features a convoluted aluminum element that maximizes surface area for efficient thermal transfer while maintaining a compact profile suitable for panel mounting. The epoxy-coated aluminum construction exceeds 1000-hour salt spray testing requirements, ensuring superior corrosion resistance in harsh industrial environments and coastal applications. A heavy-duty steel shell provides robust structural support and protects internal components from mechanical damage during installation and operation.

All units include a multi-layer corrugated aluminum filter constructed within a one-piece aluminum frame to prevent contamination of internal parts as air enters the system. The removable element access panel allows for straightforward maintenance and filter replacement, with replacement filters readily available through kooltronic.com/spareparts. The KXNP33 carries UL/CUL listing and maintains NEMA 12 rating at the mounting interface, meeting the electrical enclosure standards required for industrial and commercial installations.
