Guardian DP15 NEMA 12, 3R & 4Air-Cooled Panel-Mounted Air Conditioners

The Guardian DP15 is a panel-mounted air conditioning unit engineered to maintain precise temperature control within NEMA 12, 3R, and 4 electrical enclosures, delivering dependable cooling performance for sensitive industrial and electronic equipment. All units are fully gasketed and sealed in compliance with NEMA Type 4 enclosure ratings, ensuring tight, leakproof installation that protects internal components from environmental contaminants and moisture ingress.

This system features a closed-loop cooling design that isolates the enclosure interior airflow from ambient conditions, preventing outside air from compromising the cool, dehumidified environment essential for sensitive electronics. The built-in condensate evaporator eliminates the need for manual drainage under normal operating conditions, with overflow drain provisions and hose included for added protection in humid environments. The unit employs CFC-free R134a refrigerant and includes a compressor short cycle protector that extends compressor life by preventing frequent restarts caused by low heat loads, power interruptions, or fluctuating operational conditions--a critical safeguard for installations subject to solar gain or variable equipment usage. A multi-layer aluminum grid filter maintains internal cleanliness, with replacement filters readily available through Kooltronic's online spare parts catalog.

Construction features a heavy-duty steel shell with baked powder finish in ANSI 61 gray, complemented by epoxy-coated condenser and evaporator coils capable of withstanding 1000 hours of salt spray per ASTM B 117 testing for enhanced durability in challenging environments. Custom color finishes are available to match facility standards. The Guardian DP15 includes a programmable thermostat for precise temperature management and a programmable temperature alarm for proactive monitoring. A six-foot, 3-wire power cord is included, and the unit carries full UL/CUL listing with CE compliance, ensuring regulatory acceptance across North American and European markets.
