Description

DEFRO GAMMA is a boiler installed in central heating systems. This boiler has class 5 emission according to standard PN EN 303-5:2012 and an ECODESIGN Certificate (ecodesign). Possession of this certificate and class 5 emission allows you to apply for subsidies 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 contributed to by the use of ceramic catalysts that stabilize the combustion process. The heat exchanger was made from 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 move the fuel tank to the other side. It also has an ADAPTIVE CONTROL controller, which allows regulation of the boiler's operation based on air flow through the exchanger. It also operates 4 heating pumps, hot water, valve, control of one mixing valve, monitoring and changing the parameters of the main controller online.
