BLUE Delta

Manual fuel feed boiler of the BLUE Delta series has been developed using our best technological solutions. A number of improvements and innovative solutions have been introduced, thanks to which boiler meets the requirements of the 5th class and restrictive requirements for EKOPROJEKT (ecodesign) certificate. Our latest solution is use of a revolutionary fuel, which is "Blue Coal".

Proven Construction

Construction of BLUE Delta is based on structure tested in our backfilling boilers over the last few years. This simplest and at the same time improved with new technological achievements furnace is very effective and ecological. It is perfect for heating small and medium buildings. The boiler is manufactured using certified, high quality boiler steel and double-joint technology, which guarantees long-term tightness and greater resistance to corrosion.

Economics in costs and combustion

Boiler is simple in its construction, which guarantees simple and trouble-free operation. It can be easily operated by any user who has previously been exposed to similar technology. To clean the grate of resulting ash, we installed a handy lever on the side of boiler. BLUE Delta is also equipped with an extended flue gas circulation, using both horizontal and vertical water shelves. As a result, you consume less fuel when using blue coal properly.
