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 which means that it’s 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).

Electrical Equipment Label Temperature (C) Temperature (F)
T1 450°C 842°F
T2 300°C 572°F
T2A 280°C 536°F
T2B 260°C 500°F
T2C 230°C 446°F
T2D 251°C 483.8°F
T3 200°C 392°F
T3A 180°C 356°F
T3B 165°C 329°F
T3C 160°C 320°F
T4 135°C 275°F
T4A 120°C 248°F
T5 100°C 212°F
T6 85°C 185°F

The above chart illustrates that 200°C is the maximum surface temperature for any electrical equipment with a temperature classification of T3 or higher.
