Vitoflex 300-RF with its patented rotating combustion chamber design, features the industry’s most advanced combustion technology. An in-feed auger continuously moves the wood fuel onto a moving grate where gasification takes place. The combustible gases blend with precisely controlled secondary air, resulting in a complete combustion with ultra low emissions.  Output range:

RF 150, 154 to 512 MBH (45 to 150 kW)

RF 220, 205 to 751 MBH (60 to 220 kW)

RF 300, 273 to 1024 MBH (80 to 300 kW)

RF 400, 341 to 1365 MBH (100 to 400 kW)

RF 540, 478 to 1843 MBH (140 to 540 kW)

Vitoflex 300-UF with an attached external grate and a moving annealing grate to achieve optimal combustion results. A feed auger continuously moves the wood fuel onto the burner trough where gasification takes place. The combustible gases blend with precisely controlled secondary air, resulting in a complete combustion and the thermal energy is released into the boiler’s triple-pass heat exchanger. Output range:

UF 390, 334 to 1331 MBH (98 to 390 kW)

UF 530, 450 to 1808 MBH (132 to 530 kW)

UF 720, 614 to 2457 MBH (180 to 720 kW)

UF 950, 812 to 3242 MBH (238 to 950 kW)

UF 1250, 1065 to 4265 MBH (312 to 1250 kW)
