TrimLine Series NP33 SwitchableAir-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP33 is a switchable panel-mounted air conditioner engineered to deliver reliable, energy-efficient cooling for industrial electrical enclosures and control panels. This unit features CFC-free R134a refrigerant, an environmentally responsible choice that meets modern regulatory standards without compromising cooling performance.

A built-in condensate evaporator eliminates the need for manual condensate drainage under normal operating conditions, significantly reducing maintenance overhead and installation complexity. An overflow condensate drain fitting and hose are included as a safeguard in high-humidity environments or applications with open or leaky enclosures. The reversible condenser outlet blower accommodates flexible installation configurations, while an EMI/RFI suppressor minimizes transient line spikes during on-off cycling, protecting sensitive electronic equipment from electrical noise.

Construction quality is reinforced through multi-layer corrugated aluminum filters held securely in one-piece aluminum frames, designed to keep internal components clean and free of contaminants. An electronic thermostat with low-temperature control prevents over-cooling while optimizing energy efficiency and equipment runtime. The unit maintains full NEMA 12 compliance (UL50) through comprehensive gasketing for tight, leak-proof installation. The NP33 carries full UL/CUL listing, ensuring compliance with major safety standards. Replacement filters are available for order online at kooltronic.com/spareparts to support long-term equipment maintenance.
