Uplus & Lplus radiant tube heater ranges:

The unique design of the HYPERTUBE Uplus and Lplus range of heaters combines optimum comfort and gas savings. SBM radiant tubes can be connected in a stack configuration for the combustion air and the discharge of combustion products.

Infrared radiation through radiant tubes brings comfort directly to the users, generating energy savings. The HYPERTUBE Uplus and Lplus ranges operate on natural gas (G20 and G25) or propane (G31).
