Gāzes katls SPK 300

SPK Large water content condensing unit, entirely in stainless steel AISI 316 L, complete of pre-mix modulating gas burner, for natural gas or LPG, with NOx emissions in class 6 Output range: from 150 to 1000 kW • Maximum working pressure: 6 bar • High efficiency thanks to the special patented progressive pipes of its vertical tube bundle, tilted of 3°, in stainless steel AISI 316 L, completely rolled, with special multi-fin inserts in Al/Si/Mg. • Thermal element in vertical shape with low water side pressure losses. It doesn’t need any recirculation pump (circulation equal to boiler zero extinguished • Vertical burner with integrated check valve, placed above the combustion chamber, (modulation ratio > 1:4), with flame surface in non-resonant radiating “metallic mesh”, with thermal protection shield • Ignition and flame control through two opposite electrodes for high safety, BMM, NTC sensor for temp. control and safety thermostat • Combustion chamber inspectability guaranteed by a pneumatic opening device. • Retractable platform standard supplied (SPK 400 to 600) and optional for other models • HSCP controller is integrated in the panel board • Possibility to electronically manage up to 8 boilers (in cascade) • MULTIFUNCTION CARD for zones management SHC (“Slavic Heating Controller”), for the exploiting circuits (1 std. supplied) complete of external temperature sensor + 3 control sensors: it is possible to control up to a maximum of 4 SHC cards. • BCM (inclusive in the supply) with many additional functions. • Two different standards of communication, available in alternative • Local e-BUS interface / remote Interface
