GuardianX DP53 NEMA 4XAir-Cooled Panel-Mounted Air Conditioners

The GuardianX DP53 is a NEMA 4X-rated air-cooled panel-mounted air conditioner engineered for reliable climate control in demanding electrical enclosures, available in 208/230/220 and 480 Volt configurations. This fully gasketed, leakproof unit maintains NEMA Type 4X compliance for protection against dust, water spray, and corrosive environments, with a stainless steel shell option for applications involving harsh chemicals, moisture combinations, or salt spray exposure.

The system incorporates intelligent compressor protection through a Compressor Short Cycle Protector that prevents damage from frequent restarts caused by fluctuating heat loads, power interruptions, or solar gain. By limiting compressor starts per hour, this feature significantly extends compressor life--particularly valuable in installations where enclosure thermal demands vary seasonally or with equipment usage patterns. A closed-loop cooling design isolates the interior airflow system from ambient conditions, ensuring the sensitive component compartment remains cool and dehumidified without external air infiltration. The refrigeration circuit uses R410a refrigerant, a zero-ODP (ozone depleting potential) HFC that meets environmental regulations. Both condenser and evaporator coils feature epoxy coating that withstands 1000 hours of salt spray per ASTM B 117 test standards, while internal corrosion protection on NEMA 4X models adds an air-cured coating to refrigeration brazed joints for enhanced durability in corrosive environments.

Operational control is handled through a programmable thermostat for precise temperature management and a programmable temperature alarm that alerts operators to rising enclosure temperatures before damage occurs. The condenser blower controller optimizes cooling efficiency, while reusable multi-layer aluminum filters with non-drying adhesive coating trap particulate matter and can be washed and recoated for long service life. A six-foot three-wire power cord facilitates installation, with external junction boxes available on 480 Volt models for permanent wiring connections. The unit is UL/CUL Listed and CE Compliant, backed by refrigerant-free aluminum element construction for reliable performance in electronics cooling applications.
