{"product_id":"kooltronic-dp52-480-legacy","title":"Guardian DP52 480 Volt 3-PhaseNEMA 4 Legacy Air Conditioners","description":"\u003cp\u003eThe Guardian DP52 is a robust 480-volt, 3-phase NEMA 4 legacy air conditioning unit engineered to maintain precise environmental control in demanding industrial and commercial electrical enclosures. Its heavy-duty steel shell features a baked powder finish in ANSI 61 gray, with custom color options available to meet specific facility requirements, while the UL\/CUL listing ensures compliance with stringent safety and performance standards.\u003c\/p\u003e\n\n\u003cp\u003eThis unit incorporates advanced cooling technologies designed to minimize maintenance and extend operational life. The built-in condensate evaporator eliminates the need for manual condensate drainage under normal operating conditions, and an overflow drain fitting with hose is included for situations involving extremely high humidity. The closed-loop cooling system isolates the enclosure interior airflow from ambient conditions, preventing warm air from invading the dehumidified component compartment and ensuring consistent cooling performance. The system uses CFC-free R134a refrigerant, meeting environmental regulations while delivering reliable heat rejection. A compressor short cycle protector prevents damage from frequent restarts caused by fluctuating heat loads, power interruptions, or low-capacity utilization, thereby extending compressor life--particularly valuable in installations subject to solar gain or anticipated future equipment additions.\u003c\/p\u003e\n\n\u003cp\u003eThe Guardian DP52 features epoxy-coated condenser and evaporator coils rated to withstand 1000 hours of salt spray per ASTM B 117, providing enhanced corrosion resistance in challenging environments. A phase sequence and phase loss detector with under-voltage monitoring protects three-phase electrical systems from imbalance conditions. Programmable thermostat and temperature alarm functions enable precise climate management and early warning alerts. Multi-layer aluminum grid filters with non-drying adhesive coating trap particulates and are reuseable; replacement filters are available as needed. An external junction box accommodates permanent wiring connections, and the unit operates with full NEMA 4 rating maintained per UL50.\u003c\/p\u003e","brand":"Kooltronic","offers":[{"title":"K3NA4C7DP52L-60HZ-DP52-480-LEGACY","offer_id":47342309736684,"sku":"K3NA4C7DP52L-60HZ-DP52-480-LEGACY","price":0.0,"currency_code":"USD","in_stock":false},{"title":"K3NA4C7DP52LV","offer_id":47342309769452,"sku":"K3NA4C7DP52LV","price":0.0,"currency_code":"USD","in_stock":false},{"title":"K3NA4C9DP52L-60HZ-DP52-480-LEGACY","offer_id":47342309802220,"sku":"K3NA4C9DP52L-60HZ-DP52-480-LEGACY","price":0.0,"currency_code":"USD","in_stock":false},{"title":"K3NA4C9DP52LV","offer_id":47342309834988,"sku":"K3NA4C9DP52LV","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/guardian-dp52-480-volt-3-phasenema-4-legacy-air-conditioners-975.jpg?v=1786296997","url":"https:\/\/www.industrialautomationco.com\/products\/kooltronic-dp52-480-legacy","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
