TKU3-W is an integrated set that consists of a three pass solid fuel boiler, wood pellet burner (attached to the boiler) and a 120kg pellet storage.

It is completely adapted to burn wood pellets and it fullfils the requirements of the European machinery directive MD 2006/42 as well as the norm for solid fuel boilers EN 303/5.

Additional parts include: safety thermostate for circulation pump, thermometer, manual cleaning system of the boiler bottom („ash scrapper“), ash tray and cleaning kit.

Wood pellet burner BIOTERMEC 50.

Pellet burner consists of a burner body (which is to be mounted on the lower boiler door) and a screw-feeding system (which is put in the pellet stock beside the boiler). Flexible plastic tube is used to connect the two parts.

The control panel of the burner is on the front side of the burner body. Burner works automatically and can be programmed for each day in a week separately.

Unlike other products on the (Serbian) market, BIOTERMEC pellet burner has two feeders (controlled by two different motors). One is the main feeder that transports pellets to the burner body from the pellet storage. The other lies inside the burner and facilitates pellet feedind process to the boiler. It also acts as a protection from backfire.
