One of the last independent modifiers in the US. We explosion-proof any brand of air conditioner for any classification — installed at every major refinery in the country.
*Engineered quotes can take a week or more
Explosion-proof air conditioning is one of the most specialized fields in industrial HVAC. There are only a handful of operations in the United States qualified to do it correctly. We are one of them.
Explosion-proof HVAC is not a sideline. It's all we do. Faster answers, accurate quoting, no learning curve on complex applications.
We have been modifying and supplying explosion-proof HVAC for over a decade. Our equipment is installed across the entire US refinery system.
Most quotes come back in 24–48 hours. We don't make you wait two weeks to find out if a project is feasible.
We modify Bard, Trane, Carrier, Lennox, Mitsubishi, and any other brand to meet your exact classification. We're independent — not pushing proprietary equipment.
For the harshest environments, we coat the entire unit with Sherwin-Williams Phenicon HS — an industrial tank liner rated for brine and crude oil. No other HVAC shop offers this.
One large consolidator has acquired most explosion-proof HVAC modifiers in the United States. We remain independent — which means faster decisions, direct access to our engineering team, and no corporate layers between you and your quote. When you call us, you talk to the people doing the work.

From Gulf Coast refineries to pharmaceutical clean rooms, we've worked across the full range of hazardous location environments.
Every explosion-proof air conditioner is specified to a Class, Division, and Group. Start here if you're not sure what you need.
Flammable gas or vapor present under normal conditions. Most demanding Class 1 specification.
Flammable gas or vapor present only under abnormal conditions. Standard for most refineries and chemical plants.
Combustible dust present in suspension under normal conditions. Grain elevators, certain pharma and mining operations.
Combustible dust accumulation only. Less stringent than Division 1 but still requires rated equipment.
Every unit is custom. These are typical starting points — call us for an exact quote.
Class 1, Div 2, Group C&D. Indoor head + outdoor condenser. The budget-friendly option.
Both sections within classified area. Most common refinery configuration.
