HT DasPell GL pellet boiler. The structure is made in the form of a Heiztechnik flame exchanger. The boiler is equipped with a burner with a sludge scraper. The combustion process is controlled by individually programmed weather-compensated automatics with HT-Logic III autocontrol, which ensures smooth and user-friendly operation.
The boiler is equipped with a modern pellet burner PellHard PLUS with internal auger fuel feeder and automatic sludge scraper, activated cyclically from the controller, V-type floor, Omega-type air curtain. The burner has an automatic igniter and a photoelement for flame control. Patent Office of the Republic of Poland: Ru.069889 Ru.069890, Ru.069891.
The boiler automatics, apart from the burner operation,makes it possible to operate an advanced heating system in weather mode using a mixing valve. By connecting additional HT-tronic MZ-2 modules you can control additional elements of the heating system. Remote control with a room thermostat ensures operation of the system for comfortable temperature of heated rooms. The controller controls the operation of the burner by modulating the power depending on the boiler temperature. Operation in HT-Logic III mode, which is individually programmed for each boiler, automatically selects operating parameters and modulates the burner power depending on the boiler temperature. The automation can be equipped with a large colour display and an internet module.
The boiler has a burner fitted only on the front. GreenLine series boilers meet the environmental protection and energy efficiency requirements of the 5th class (the highest) set out in the PN-EN 303-5:2012 standard, and are certified by the “Polskie Ciepło” programme. (*option)
