Profile Series DP21Air-Cooled Panel-Mounted Air Conditioners

The Profile Series DP21 Air-Cooled Panel-Mounted Air Conditioner is a versatile, compact cooling solution engineered for internal or external enclosure mounting, delivering precise temperature control and dependable performance in industrial electrical environments. With its exceptionally narrow depth, the DP21 represents Kooltronic's thinnest line of indoor/outdoor air conditioners, enabling installations in space-constrained applications where traditional units cannot fit. The unit operates on CFC-free R134a refrigerant, meeting environmental standards while providing efficient cooling capacity.

Constructed with a heavy-duty steel shell finished with baked powder coating in ANSI 61 gray--with custom color options available upon request--the DP21 provides robust protection against standard industrial environments. The fully gasketed design maintains NEMA 12 and 3R ratings per UL50 for tight, leakproof operation. An epoxy-coated condenser coil delivers corrosion resistance rated to 1000 hours of salt spray per ASTM B 117, making it suitable for moderately corrosive settings. A built-in condensate evaporator eliminates the need for manual condensate drainage under normal operating conditions, with overflow drain fittings and hose included for additional safeguard.

The DP21's closed-loop cooling architecture isolates the enclosure interior from ambient airflow, preventing warm or humid outside air from compromising sensitive component compartments. A compressor short cycle protector extends equipment life by preventing harmful restart cycles during power interruptions or low heat load conditions, particularly valuable where solar gain or fluctuating internal loads are anticipated. The programmable thermostat and temperature alarm provide precise, versatile control with early warning alerts. This model is UL/CUL Listed and normally stocked for rapid deployment.
