TrimLine Series NP/NPT47Air-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP/NPT47 air-cooled panel-mounted air conditioners deliver efficient, closed-loop cooling specifically designed to protect sensitive electronic components in industrial enclosures. These units employ a closed-loop cooling architecture that completely isolates the enclosure interior airflow system from ambient conditions, preventing warm or contaminated air from invading the protected component compartment and ensuring consistent dehumidified cooling performance.

The NP and NPT series differ in their refrigerant technology. The NP Series utilizes CFC-free R134a refrigerant, while the NPT Series employs R410a, an HFC refrigerant with zero ozone depleting potential, providing environmentally responsible operation. Both lines feature a built-in condensate evaporator that eliminates the need for condensate drainage under normal operating conditions, though overflow drain fittings and hoses are included for installations in extremely high humidity environments or where enclosures may have air leaks. An electronic thermostatic low-temperature control thermostat prevents over-cooling while optimizing energy efficiency, and a high-pressure limiter switch provides critical system protection. Multi-layer corrugated aluminum filters with sturdy one-piece aluminum frames are included to keep internal components clean; replacement filters are readily available through kooltronic.com/spareparts.

The NPT47 models maintain both NEMA 12 and 3R ratings per UL50 and are UL/CUL Listed, while NP47 models maintain NEMA 12 ratings with UL/CUL Listed or Recognized status depending on configuration. Recognized models can be upgraded to Listed certification at additional cost. All units include a condenser impeller controller for reliable thermal management in demanding industrial applications.
