TrimLine Series NP28Air-Cooled Panel-Mounted Air Conditioners

The TrimLine Series NP28 is an air-cooled panel-mounted air conditioner designed to maintain precise temperature and humidity control within sensitive electronics enclosures while protecting internal components from contamination. This unit employs a closed-loop cooling system that completely isolates the enclosure interior airflow from ambient conditions, ensuring that cool, dehumidified air circulates only through the sensitive component compartment with no risk of ambient air infiltration.

The NP28 features a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, streamlining installation and reducing ongoing maintenance requirements. In applications with extremely high humidity or open enclosures, an overflow condensate drain fitting and hose are included as a safeguard. The unit utilizes CFC-free R134a refrigerant, supporting environmental compliance while delivering reliable thermal management. An electronic thermostatic low temperature control prevents over-cooling and optimizes energy efficiency by maintaining setpoint temperatures precisely.

Construction includes a robust multi-layer corrugated aluminum filter secured in a one-piece aluminum frame to capture airborne contaminants and protect internal electronics from dust and debris. All components are fully gasketed for leak-proof installation, meeting NEMA 12 Enclosure Ratings per UL50 standards. The unit carries UL/CUL listing for safety and performance verification. Replacement filters are readily available through Kooltronic's online spare parts portal at kooltronic.com/spareparts, ensuring long-term serviceability and continued protection of critical equipment.
