Proven performance in the most challenging environments

 

  • UL Listed for Class 1, Division 2, Groups A, B, C and D
  • Certified in accordance with ISA 12.12.01 and NFPA 70 (National Electric Code), ANSI/UL 484 Room Air Conditioners
  • KSA Registered and tested in accordance with SASO 2681

For more than three decades, global industry and high-tech leaders have trusted Hazardgard to provide commercial-grade cooling under the harshest conditions. You’ll find durable, reliable Hazardgard room air conditioners on oil rigs and military bases, in manufacturing companies and processing plants – anywhere hazardous materials are used. Hazardgard is specifically designed to cool spaces where volatile, flammable liquids and gases are used, within enclosed systems or containers, or under extreme temperatures..

Temperature Classification

Electrical equipment, like hazardous location air conditioners, that may be exposed to specific, hazardous gases or vapors in the area where it will be used, cannot reach temperatures that exceed 80% of the auto-ignition temperature of those gases or vapors. Hazardgard has a T4 rating, meaning its surface temperature should not exceed 135°C or 275°F. (Note: 50/60Hz model listed as T4A for surface temperatures to 120° C/248° F).
