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.

Anti-corrosive Diamonblue Technology comes standard Diamonblue™ anticorrosive coating for metals is an advanced corrosion protection treatment that protects the outdoor coil and extends unit life, especially in harsh coastal environments.

ElectroFin® 5-stage, immersion ecoat process on 100% of metallic surfaces on the outdoor coil provides outstanding corrosion resistance protection in coastal or corrosive environments.
