Providing clean, dry heat, the XE1300 portable heater uses magnets and eddy currents as a heat-producing source. The currents produce no gaseous odors, emissions, or moisture, leaving the environment clean, dry, and comfortable. It easily converts from a portable heater to a surface heater for concrete curing and ground thawing. Standard propane and optional diesel models are available. MagTec Energy LLC. 877-624-4328.
