For more than 30 years, industrial professionals have trusted Hazardgard® to deliver safe and reliable cooling in the most extreme conditions. Hazardgard® is specifically designed to cool laboratories, control rooms, living quarters, storage areas and other enclosures situated in hazardous locations; where specific volatile flammable liquids or gases are handled or used within enclosed containers or systems.
Hermetically sealed reciprocating compressor is cooled during the refrigeration cycle, which allows the unit to tolerate higher outdoor temperatures up to 130ºF/55ºC. Equipped with hot gas bypass for cooling operation at low ambient temperatures, down to 45ºF/7ºC without freezing.
Robust engineering, commercial grade components and extensive field testing provide the durability and safety required in hazardous locations.
Unit surface temperatures will not rise above 275°F/135°C. Hazardgard® can tolerate higher outdoor temperatures up to 130°F/55°C. Unit will operate at low ambient conditions without freezing at outdoor ambient temperatures as low as 45°F/7°C.
ElectroFin® 5-stage, immersion ecoat process, or Diamonblue Advanced Corrosion Protection® on 100% of metallic surfaces on the outdoor coil provides outstanding corrosion resistance protection and extends the life of the unit, especially in coastal or corrosive environments. MODEL SH24N30A ONLY.
Hazardgard®’s reliable design is backed by robust engineering. Used across the globe, Hazardgard® is a tested and reliable product and not a quick-fix, job shop alteration.
