Profile Series DP53 External MountAir-Cooled Panel-Mounted Air Conditioners

The Profile Series DP53 is an external mount, air-cooled panel-mounted air conditioner engineered to maintain precise temperature and humidity control within sensitive electronics enclosures while operating in demanding industrial environments. Its closed-loop cooling design isolates the interior airflow system from ambient conditions, preventing warm, humid outside air from contaminating the protected component compartment and ensuring consistent, dehumidified cooling performance.

The unit features a heavy-duty steel shell with a durable textured baked powder finish and maintains NEMA 12 and 3R ratings through full gasket sealing for tight, leakproof installation. The epoxy-coated condenser coil provides robust corrosion resistance, withstanding 1000 hours of salt spray testing per ASTM B 117, though severe operational environments such as wastewater treatment facilities may require consultation with the factory regarding extended warranty coverage and additional corrosion protection options. All units employ either CFC-free R134a or low-ODP R22 refrigerant depending on model configuration, with the model number designation clarifying refrigerant type.

The DP53 incorporates an electronic low-temperature control thermostat for energy-efficient operation that prevents over-cooling, a condenser blower controller for optimized fan performance, and an EMI/RFI suppressor that minimizes transient line spikes during on-off cycling. The multi-layer corrugated aluminum filter with one-piece aluminum frame keeps internal components clean and is easily replaceable through Kooltronic's online spare parts portal. This unit is UL/CUL Listed and delivers reliable performance in space-constrained installations requiring external mounting.
