TrimLine Series NP33Air-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP33 is an air-cooled, panel-mounted air conditioning unit designed to maintain precise temperature control within industrial and electronic equipment enclosures while protecting sensitive components from contamination and humidity. This system features a closed-loop cooling design that completely isolates the enclosure's internal airflow from ambient conditions, preventing warm or humid air from invading the protected compartment and compromising equipment performance.

The unit incorporates a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, reducing maintenance requirements and installation complexity. An overflow condensate drain fitting and hose are provided as backup protection for extreme humidity situations or in applications with open or leaky enclosures. Cooling is delivered using environmentally responsible CFC-free R134a refrigerant, meeting modern environmental standards. An electronic thermostat with low temperature control prevents over-cooling while optimizing energy efficiency, ensuring cost-effective operation across varying seasonal demands.

The NP33 features a high-quality multi-layer corrugated aluminum filter in a one-piece aluminum frame, protecting internal components from dust and airborne contaminants that can degrade reliability. Replacement filters are readily available for reordering through kooltronic.com/spareparts. The unit maintains NEMA 12 Enclosure Rating compliance per UL50, with fully gasketed construction providing tight, leak-proof installation for demanding industrial environments. The TrimLine Series NP33 is UL/CUL Listed, meeting rigorous safety and performance standards for equipment protection in controlled environment applications.
