Chromalox Industrial Unit Heaters include both fixed and portable designs and incorporate a powerful fan to help circulate the warm air produced by the heating elements.  Adding a fan creates air movement that allows for a design that is more compact than an equivalent convection heater since rapidly moving air removes the heat from the element surface quickly. Our heaters are designed to withstand dusty, dirty environments, and to hold up against typical abuse seen in industrial environments.
