The US Military uses DC Thermal heaters to provide extra warmth in their Hum V’s while they are on missions in extreme cold. DC Thermal has also provided Los Angeles Metro with heaters for their subway systems. Birds Eye Foods use our heaters in cold storage 24 hours a day, 365 days a year. Gatorade also uses DC Thermal heaters on their fork trucks in cold storage. These are extreme conditions and environments, most heaters wouldn’t last a few days when subjected to this type of treatment. If you have a need for heat on any cabin or DC voltage vehicle, DC Thermal can accommodate you.
