{"product_id":"kooltronic-dp38l-480v","title":"GuardianX DP38 480 Volt 3-PhaseNEMA 4X Air Conditioners","description":"\u003cp\u003eThe GuardianX DP38 is a 480-volt, 3-phase NEMA 4X air conditioning unit engineered to maintain precise environmental control within electrical enclosures while delivering exceptional protection against corrosion and operational hazards. Fully gasketed and rated to NEMA Type 4X specifications, this unit provides a leakproof seal that keeps hostile external elements from compromising sensitive internal components, making it ideal for chemical plants, wastewater treatment facilities, coastal installations, and other demanding industrial environments.\u003c\/p\u003e\n\n\u003cp\u003eThe closed-loop cooling design isolates the enclosure interior airflow system from ambient conditions, ensuring that only cool, dehumidified air reaches critical electronics while preventing contamination from external air or moisture. A built-in condensate evaporator eliminates the need for manual drainage under normal operating conditions, though an overflow drain fitting and hose are included for installations experiencing extreme humidity or enclosure leakage. The refrigeration system features CFC-free refrigerant and internal corrosion protection with air-cured brazed joint coatings that withstand 1000 hours of salt spray testing per ASTM B 117, supplemented by epoxy-coated condenser and evaporator coils for enhanced durability. A multi-layer corrugated aluminum filter maintains internal cleanliness and protects components from airborne contaminants.\u003c\/p\u003e\n\n\u003cp\u003eAdvanced controls ensure reliable, efficient operation across variable load conditions. The compressor short cycle protector prevents damage from frequent restarts caused by fluctuating heat loads or power interruptions, significantly extending compressor life--particularly important in installations with solar gain or anticipated future equipment additions. A solid-state condenser impeller speed controller modulates fan speed based on coil temperature, reducing noise, minimizing compressor cycling, and preventing freeze-up. The unit includes a programmable thermostat for precise temperature management, a programmable temperature alarm for proactive maintenance alerts, and phase sequence and phase loss detection with under-voltage monitoring for safe three-phase operation. An external junction box accommodates permanent wiring connections, while UL\/CUL listing confirms compliance with recognized safety standards.\u003c\/p\u003e","brand":"Kooltronic","offers":[{"title":"K3NA4C5DP38LV-60HZ","offer_id":47342303510764,"sku":"K3NA4C5DP38LV-60HZ","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/guardianx-dp38-480-volt-3-phasenema-4x-air-conditioners-k3na4c5dp38lv-60hz-253.jpg?v=1786296423","url":"https:\/\/www.industrialautomationco.com\/products\/kooltronic-dp38l-480v","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
