GuardianX DP43 NEMA 4XAir-Cooled Panel-Mounted Air Conditioners

The GuardianX DP43 is a NEMA 4X-rated, panel-mounted air conditioning unit engineered to provide reliable thermal management and environmental protection for sensitive electrical enclosures in demanding industrial settings. Fully gasketed for leakproof installation and compliant with UL/CUL and CE standards, this unit delivers closed-loop cooling that isolates the enclosure interior from ambient air and moisture, ensuring that sensitive components remain in a cool, dehumidified environment protected from contamination.

The unit features a built-in condensate evaporator that eliminates the need for manual drainage under normal operating conditions, with an overflow drain fitting and hose included for extra protection. CFC-free R134a refrigerant supports environmental sustainability while maintaining cooling efficiency. An epoxy-coated condenser and evaporator assembly resists corrosion through 1000 hours of salt spray testing per ASTM B 117, with internal corrosion protection on the refrigeration system's brazed joints providing additional safeguards in harsh environments. For applications in severe corrosive conditions, a stainless steel shell option is available. A multi-layer corrugated aluminum filter prevents contaminants from entering the system, with replacement filters readily available through Kooltronic's online spare parts catalog.

The DP43 incorporates intelligent control features that extend compressor life and reduce operational wear. A compressor short-cycle protector prevents premature restarts after shutdown or power interruption, extending component longevity in applications with fluctuating loads or solar exposure. A solid-state condenser impeller speed controller modulates fan speed based on coil temperature, reducing noise, fan cycling, and compressor cycling while preventing freeze-up. All models include a programmable thermostat for precise temperature management and a programmable temperature alarm for proactive monitoring. The unit ships with a six-foot three-wire power cord and is normally stocked for rapid deployment.
