CWD Group products

Using the latest outdoor gasifier technology, we reduce CO2 emission and other dioxids which can  be released into the atmosphere during wood combustion.

Biowarmer series is offered for sawmill, wood furniture factories or carpentry industry. Offered boiler is new but refabrished with fully guarantee from factory.

Multi fuel heating boilers with manual loading LogiKa  are heating devices designed to burn most popular fuel on the market : wood , brown /stone coal, peat briquettes and pellets. The upper-lower combustion system allows to burn different types of fuel and low quality fuels.

Versatile standing solid fuel boilers VESPA CWD are compact and price attractive wood/coal/pellets units. Ultima III are down combustion boilers - it allows for fuel refilling every time during operation of boiler becouse combustion chamber is in down part of loading chamber. VESPA BOILERS are excelent units as side ( spare ) boilers by  oil or gas boilers. Boiler starts very fast, catch temperature quickly  and has big loading doors and extended loading chamber.

Sigma boilers are devices that use to burn wood logs in the process of gasification. Modern wood gasification boilers are up to 2 times more efficient than traditional methods of combustion and emission of harmful substances into the atmosphere is much lower.. When burning wood with a limited air supply Thermochemical processes occur that result in the production of wood gas. This gas is directed to the burner nozzle where it mixed with air to form a gas flame at the bottom of the boiler. Sigma wood gasification unit fully utilize a closed fuel energy which allows for the highest emission parameters

Kumulator Eko is the lower combustion  system boiler. This system provides slower and more precisely an economical burning. Exhaust gas boiler circulate by three hot gas flues, which can significantly extend their path and thus to increase heat transfer efficiency. For Kumulator Eko boilers is recommended chunk of wood. Humidity max. 15-20% , diameter 10-20 cm. Wood should be from deciduous trees like: Oak, Bebech, Acacia, Hornbeam, Ash. or softer wood like birch or poplar. As substitude can be use wood from coniferous trees. There is possibility to instal pellet burner in the combustion chamber door.
