Industrial heaters are used to covert energy from a fuel or energy source to thermal energy in a system, process stream or closed environment. The process by which thermal energy is transformed from an energy source to a system can be described as heat transfer.
Air heaters are devices used to heat air. They include forced air products as well as all types of radiant and space heaters. Forced air products moderate and control air temperature by circulating air past a heat source with a fan or blower.
One important application of industrial heating is heating heavy liquids, including crude oil derivatives and crude oil itself. Electric heaters are used to reduce the viscosity of these fluids. Reducing viscosity can increase the mobility of the fluid.
