TrimLine Series NP28 SwitchableAir-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP28 is a switchable, air-cooled panel-mounted air conditioner designed to maintain optimal temperature control in electrical enclosures while minimizing operational complexity and maintenance demands. This unit integrates a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, significantly reducing maintenance overhead. An overflow condensate drain fitting and hose are included as standard protection against condensate backup in high-humidity environments or installations with open or leaky enclosures.

The NP28 operates on CFC-free R134a refrigerant, supporting environmentally responsible cooling without compromising performance. An EMI/RFI suppressor is integrated to minimize transient line spikes during on-off cycling, protecting sensitive electronic equipment from electrical interference. The unit features an electronic thermostatic control system with low-temperature sensing that prevents over-cooling while delivering energy-efficient operation tailored to actual cooling demands.

All air intake is protected by a multi-layer corrugated aluminum filter secured in a sturdy one-piece aluminum frame, keeping internal components clean and extending equipment service life. The NP28 maintains NEMA 12 enclosure ratings per UL50, with full gasket sealing throughout for leak-proof installation in demanding industrial environments. The unit is UL/CUL Listed, and replacement filters are readily available through kooltronic.com/spareparts for convenient ordering and planned maintenance scheduling.
