Safe Heating and Cooling Equipment For usage in hazardous regions, the HL28LV Series from Kooltronic has been classified as both Class I Division I and Class I Division II. With NEMA 4/4x certification. The Kooltronic Hazardous Site Series Air Conditioners provide the durability and safety that hazardous location applications demand because of their strong engineering, industrial-grade construction, and UL Listing.
US Patent and Trademark Office awarded HL28LV Series with a patent (U.S. Patent No. 9,157,670 B2). A significant step forward in terms of both safety and dependability has been achieved by enclosing all electrical components in a pressurized chamber. Use of the electrical enclosure’s existing purge system and the use of general-purpose components reduces both upfront and maintenance expenses.
Single-phase and three-phase power output up to 3,000 BTU/H are available in the HL28LV Series. Programmable thermostat and compressor short cycling guard are among the typical features. Compared to typical hazardous sites, these units are more affordable and easier to maintain. These corrosive- and hazardous-gas-resistant stainless steel components are ideal for a variety of industrial applications.
