Improved Performance Starts Here

Since 1942, Hotstart has been the world leader in the design and manufacture of thermal management systems. The initial need of keeping school buses warm in winter resulted in engine heating products that continue to be used by major OEMs globally. With over 75 years of experience, the company continues to provide high quality, reliable preheating systems to customers needing easy engine starts, immediate full power and reductions in maintenance, fuel consumption and harmful emissions. 

As the energy landscape evolves, we are drawing on our expertise to develop innovative heating and cooling solutions. Power generation, storage and delivery methods are changing quickly and require new approaches to achieve sustainability and energy-efficiency goals. Targeted, liquid-based thermal management in place of traditional air conditioning is ideal for battery energy storage, fuel cells and electrified industrial vehicles.  

“We have 200 extremely talented, gifted, fun people that work together well as a team. They care about each other, they care about their work and they care about their customers. Great things happen when we all row together in the same direction.”

—Terry Judge, CEO 


“My grandfather, Stanley Power, started up the company in 1942—75 years ago. The company has been amazingly successful because of the people that we have. Everything else falls into place. Customers get taken care of—the right things happen.”

—Rick Robinson, Retired CEO
