Description
DEFRO GAMMA is a boiler mounted in central heating installations. This boiler has a 5 emission class according to the PN EN 303-5:2012 standard and an ECODESIGN Certificate. Having this certificate and a 5 emission class allows you to apply for a subsidy for its purchase and installation. During the production process, a pellet burner was used which has a self-cleaning function and an automatic fuel ignition system as standard. A spacious fuel tank allows operation without refueling with pellets for several days, which is facilitated by the use of ceramic catalysts that stabilize the combustion process. The heat exchanger was made of high-grade boiler steel. The shape of the exchanger ensures high efficiency and ease of cleaning. Thanks to its innovative structure, it is equipped with the ability to shift the fuel tank to the other side. It also has an ADAPTIVE CONTROL controller, which allows you to adjust the boiler operation based on the air flow through the heat exchanger. It also operates 4 central heating pumps, hot water, valve, control of one mixing valve, view and change of main controller parameters online.
