{"product_id":"kooltronic-hl60","title":"Hazardous Location Series HL60LVClass 1 Division 1 and 2 Air Conditioners","description":"\u003cp\u003eThe Hazardous Location Series HL60LV is a Class 1 Division 1 and 2 air conditioning unit purpose-built for explosive and hazardous environments, delivering reliable thermal management for sensitive electrical enclosures in industrial settings where safety compliance is non-negotiable. All models are UL Listed per Standard 484 for Special Purpose Air Conditioners and UL Recognized per NFPA 496: 2013 for Purged and Pressurized Enclosures, ensuring compliance with NEC Class I Division 1 and Division 2 hazardous location requirements (Groups A, B, C, and D) when paired with appropriate Type X or Type Z purge systems on the electrical enclosure. The unit carries a T-4 temperature classification rated to 275F\/135C and is CE Compliant for international applications.\u003c\/p\u003e\n\n\u003cp\u003eThe HL60LV employs a closed-loop cooling design that completely isolates the enclosure interior airflow system from ambient or external water flow, preventing any contamination of the sensitive component compartment with outside air. A built-in compressor short cycle protector safeguards the refrigeration system from damage caused by frequent start-stop cycling, which is critical in installations subject to solar gain, fluctuating heat loads, or power interruptions that could otherwise shorten compressor life. The unit features a programmable thermostat and programmable temperature alarm, enabling precise temperature control and early alert capabilities for proactive maintenance. Multi-layer corrugated aluminum filters with one-piece aluminum frames prevent debris accumulation, with replacement filters readily available through the manufacturer's spare parts portal.\u003c\/p\u003e\n\n\u003cp\u003eConstructed to maintain NEMA Type 12, 3R, and 4\/4X enclosure ratings under demanding conditions, the HL60LV incorporates shock and vibration resistance rated for 4 hours per plane at 1G acceleration in multiple planes. The unit features painted condenser and evaporator coils, interior and exterior purge connections, and a pressure compensation terminal block for auxiliary pressure supply. For corrosive environments, internal corrosion protection coating on brazed joints withstands 1000 hours of salt spray testing per ASTM B 117, with optional stainless steel shell construction available for enhanced protection in chemical and moisture-laden atmospheres. The system uses R410a refrigerant, an HFC with zero ozone depleting potential, meeting modern environmental standards.\u003c\/p\u003e","brand":"Kooltronic","offers":[{"title":"K3A6C24HL60LV-60HZ","offer_id":47342289060076,"sku":"K3A6C24HL60LV-60HZ","price":0.0,"currency_code":"EUR","in_stock":false},{"title":"K3A6C24HL60LV-50HZ","offer_id":47342289092844,"sku":"K3A6C24HL60LV-50HZ","price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/hazardous-location-series-hl60lvclass-1-division-and-2-air-conditioners-807.jpg?v=1786295616","url":"https:\/\/www.industrialautomationco.com\/de-de\/products\/kooltronic-hl60","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
