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.
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).
The above chart illustrates that 200°C is the maximum surface temperature for any electrical equipment with a temperature classification of T3 or higher.
|Gas||Temperature (C)||Temperature (F)|
Some surfaces, like that of a high-pressure steam pipe, can have a greater auto-ignition temperature than certain mixtures of fuel and air.
As seen on the chart below, the auto-ignition temperature of dust is typically greater than the auto-ignition temperature of vapors and gases. Such examples include:
|Substance||Temperature (C)||Temperature (F)|
Robust engineering, commercial-grade components and extensive field testing show that Hazardgard provides the durability and safety required in hazardous locations. See the complete features list for details on what makes Hazardgard the best choice in tough operating environments.
Hazardgard is ideal for:
Electrofin meets the following:
Hazardgard can be installed in a window or thru-the-wall, provided the wall depth meets specifications. See the specifications by model for details.
