GuardianX DP15 NEMA 4XAir-Cooled Panel-Mounted Air Conditioners

The GuardianX DP15 is a NEMA 4X-rated, air-cooled panel-mounted air conditioner engineered to maintain precise temperature control within sensitive electrical enclosures while providing superior protection against corrosive and hostile environments. This fully gasketed unit achieves and maintains NEMA Type 4X compliance, ensuring a leakproof installation that prevents ambient air infiltration and contamination of critical component compartments. The stainless steel shell offers exceptional durability in corrosive settings such as chemical processing facilities and coastal installations, while internal corrosion protection consisting of an air-cured coating applied to refrigeration system brazed joints provides additional safeguarding against salt spray and moisture-related degradation.

The DP15 incorporates a closed-loop cooling design that completely isolates the enclosure interior airflow from ambient air and water systems, ensuring that cool, dehumidified air reaches sensitive components without exposure to external contaminants. A built-in condensate evaporator eliminates the need for manual drainage under normal operating conditions, significantly reducing maintenance requirements, though overflow condensate drain fittings and hose are provided for installations in extremely humid environments. The system uses CFC-free R134a refrigerant, supporting environmental compliance while delivering reliable heat removal. Epoxy-coated condenser and evaporator coils, rated to withstand 1000 hours of salt spray per ASTM B 117 testing, provide long-term corrosion resistance in demanding applications.

The DP15 features a compressor short cycle protector that extends motor life by preventing rapid restart cycles that can occur during low heat loads, power interruptions, or fluctuating enclosure temperatures, making this feature especially valuable in installations subject to solar gain or future equipment additions. Programmable thermostat and temperature alarm functions enable precise climate control and early warning of thermal deviations, allowing operators to take corrective action before problems develop. A multi-layer corrugated aluminum filter with a sturdy one-piece frame keeps internal components clean, with convenient replacement parts available online. The unit comes with a minimum six-foot three-wire power cord and is UL/CUL Listed and CE Compliant, meeting international safety and regulatory standards.
