"BTwin" BTH2R

Radiant heating for medium to high industrial buildings with or without insulation. U-shaped emitter tube, high combustion and radiation efficiency. sustainable high efficiency heater

  • Heats an entire building, a zone or a workstation
  • Works in the same way as sun rays
  • Displaces no air or dust
  • Significantly reduces energy consumption: 20 to 50 % compared to conventional systems
  • Exceptional radiation efficiency: 73 %
  • Produces and emits heat directly without any transfer fluid
  • Reaches full output very quickly

profile of the BTH2R highly efficient radiant heater

The converter transforms convected heat into radiated heat. In this way, higher efficiency is obtained and consumption of energy is reduced.
