Overview

As raw materials, you can use coal, Anthracite, firewood, briquettes, peat, woodworking waste, briquetted husk, straw, waste paper - fuel supply is manual. It is possible to use fuel raw materials with high humidity (60% or more).
Purpose: it is used for central heating of individual housing and residential complexes, administrative, industrial and warehouse premises, especially wood processing enterprises, livestock complexes, pavilions, greenhouses, schools, shops, medical institutions.
Boilers have a number of advantages: efficiency up to 86-93%; the robust body of the combustion chamber made of steel with a thickness of 6 mm provides the service life of the equipment for 15 years or more; the system of dissecting the air flow throughout the entire volume of the furnace, the possibility of forming an "air cocoon" in the combustion chamber due to the regulation of air flows, which ensures complete combustion of fuel, allows you to achieve maximum heat transfer and significantly extend the combustion process; the possibility of combining direct-flow and pyrolysis combustion method; the possibility of cleaning air injectors and air channels in the process of their contamination; the system of adjusting air flows for any type of solid fuel and combustible waste; electronic control of forced air supply with the possibility of installing a climate thermostat and remote control functions; five years warranty on the heat exchanger; heat removal retention system with flue gases, the temperature of which in stable boiler mode is 90-110 °C; one-time fuel loading is from 7-36 hours; boilers are distinguished by high performance and reliability, supported by numerical differences; if necessary, boilers are equipped with an automated fuel supply system.
