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. (BR)(BR)(/P)(BR)(B)Temperature Classification(/B)(BR)(P)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(degree)C or 275(degree)F. (Note: 50/60Hz model listed as T4A for surface temperatures to 120(degree) C/248(degree) F).(/P) (P)MODELS SH15M30A, SH20M30A, SH20M50A(/P)(UL)(LI)DiamonBlue(TM) Advanced Corrosion Protection on the outdoor coil protects the coil against deterioration and extends the life of the unit especially in coastal or corrosive environments (/LI)(/UL)(P)ElectroFin(R) 5-stage, immersion ecoat process on 100% of metallic surfaces on the outdoor coil provides outstanding corrosion resistance protection in coastal or corrosive environments.
