{"product_id":"kooltronic-dp43l","title":"Guardian DP43 NEMA 12, 3R \u0026 4Air-Cooled Panel-Mounted Air Conditioners","description":"\u003cp\u003eThe Guardian DP43 is a heavy-duty, panel-mounted air conditioning unit designed to maintain precise temperature control within NEMA 12, 3R, and 4 rated electrical enclosures. Its baked powder-coat finish in ANSI 61 gray provides robust protection against industrial environments, with custom color options available to match facility aesthetics or specifications.\u003c\/p\u003e\n\n\u003cp\u003eThis unit employs a closed-loop cooling system that isolates the enclosure interior airflow from ambient conditions, preventing unconditioned air from infiltrating the protected component compartment and ensuring consistent dehumidification of sensitive electronics. The built-in condensate evaporator eliminates routine drainage requirements under normal operating conditions, while an overflow drain fitting and hose are included for installations in high-humidity environments. CFC-free R134a refrigerant delivers efficient cooling while meeting environmental regulations. The epoxy-coated condenser and evaporator coils provide extended service life in corrosive environments, withstanding 1000 hours of salt spray per ASTM B 117 standards, making the unit suitable for challenging operational settings such as coastal installations or industrial facilities. A multi-layer corrugated aluminum filter protects internal components from contamination, with replacement filters readily available online.\u003c\/p\u003e\n\n\u003cp\u003eThe Guardian DP43 incorporates advanced protection and control features that extend equipment life and reduce operational costs. A compressor short-cycle protector prevents damage from frequent restarts caused by fluctuating heat loads or power interruptions, significantly extending compressor longevity--particularly valuable in installations with variable internal loads or solar exposure. A solid-state condenser impeller speed controller automatically adjusts fan speed based on coil temperature, reducing noise, minimizing compressor cycling, and preventing freeze-up conditions. Programmable thermostat and temperature alarm functions provide precise temperature management and early warning of thermal issues. The unit is supplied with a six-foot three-wire power cord, is fully gasketed to maintain NEMA ratings, and carries UL\/CUL listing and CE compliance certifications for global deployment.\u003c\/p\u003e","brand":"Kooltronic","offers":[{"title":"KNA4C7DP43L","offer_id":47342305018092,"sku":"KNA4C7DP43L","price":0.0,"currency_code":"USD","in_stock":false},{"title":"K2NA4C7DP43L","offer_id":47342305050860,"sku":"K2NA4C7DP43L","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/guardian-dp43-nema-12-3r-4air-cooled-panel-mounted-air-conditioners-462.jpg?v=1786296558","url":"https:\/\/www.industrialautomationco.com\/products\/kooltronic-dp43l","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
