TrimLine Series NP33Air-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP33 Air-Cooled Panel-Mounted Air Conditioners deliver reliable thermal management for sensitive electronics and control equipment housed in industrial enclosures. Each unit features a heavy-duty steel shell with a baked powder finish in ANSI 61 gray, providing exceptional corrosion resistance and durability in demanding environments. Custom color options are available to match facility aesthetics or identification standards.

The closed-loop cooling system isolates the enclosure interior airflow from external ambient air, preventing contamination of sensitive components while maintaining precise dehumidification within the protected compartment. A built-in condensate evaporator eliminates the need for manual condensate drainage under normal operating conditions, reducing maintenance requirements and simplifying installation. An overflow condensate drain fitting and hose are included for applications in high-humidity environments or installations with open or leaky enclosures. The multi-layer corrugated aluminum filter captures particulates and debris before air enters sensitive areas, with replacement filters readily available through Kooltronic's online spare parts catalog.

Advanced controls and environmental protections ensure long-term reliability and peace of mind. A compressor short cycle protector prevents damage from frequent restarts caused by fluctuating heat loads, power interruptions, or oversized capacity units, extending compressor life and lowering operational costs. The programmable thermostat enables accurate temperature control across diverse applications, while a programmable temperature alarm alerts operators when conditions require intervention. The optional low ambient kit maintains proper operating pressures when temperatures fall below 50 degrees Fahrenheit, with effectiveness down to 0 degrees Fahrenheit through integrated compressor heating and pressure modulation. All units operate on CFC-free R134a refrigerant, maintain NEMA 12 gasket sealing for leak-proof installation in compliance with UL50 standards, and carry full UL/CUL listing for code compliance.
