{"product_id":"kooltronic-dp52-480v","title":"Guardian DP52 480 Volt 3-PhaseNEMA 4 Air Conditioners","description":"\u003cp\u003eThe Guardian DP52 is a 480-volt, 3-phase NEMA 4 air conditioning unit engineered to provide reliable, closed-loop cooling and dehumidification for sensitive electrical enclosures and industrial equipment. Its heavy-duty steel shell features a baked powder finish in ANSI 61 gray, with custom color options available, ensuring durability and professional appearance in demanding industrial environments.\u003c\/p\u003e\n\n\u003cp\u003eThis unit incorporates several advanced protective systems designed to maximize equipment lifespan and operational efficiency. The built-in condensate evaporator eliminates the need for manual condensate drainage under normal operating conditions, with an overflow drain fitting and hose included for added safety. A compressor short cycle protector prevents damage from harmful frequent restarts, particularly valuable in installations subject to variable heat loads, solar gain, or power interruptions--extending compressor life by limiting the number of starts per hour. The closed-loop cooling design isolates the enclosure interior airflow from the ambient environment, preventing warm or humid outside air from compromising the dehumidified component compartment. The epoxy-coated condenser and evaporator coils provide robust corrosion resistance, withstanding 1000 hours of salt spray per ASTM B 117 standards, though severe corrosive environments may require additional protection options.\u003c\/p\u003e\n\n\u003cp\u003eThe Guardian DP52 operates on CFC-free refrigerant for environmental compliance and features a programmable thermostat and temperature alarm system that alert operators to temperature deviations before they become critical. Multi-layer aluminum filters with adhesive coating trap particulate matter and are reusable after washing and recoating. Additional safeguards include phase sequence and phase loss detection with under-voltage monitoring to protect against electrical irregularities, an external junction box for permanent wiring connections, and full UL\/CUL listing to meet applicable safety standards.\u003c\/p\u003e","brand":"Kooltronic","offers":[{"title":"K3NA4C7DP52L-60HZ","offer_id":47342304231660,"sku":"K3NA4C7DP52L-60HZ","price":0.0,"currency_code":"EUR","in_stock":false},{"title":"K3NA4C9DP52L-60HZ","offer_id":47342304264428,"sku":"K3NA4C9DP52L-60HZ","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/guardian-dp52-480-volt-3-phasenema-4-air-conditioners-797.jpg?v=1786296469","url":"https:\/\/www.industrialautomationco.com\/de-de\/products\/kooltronic-dp52-480v","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
