Boiler Retra-3М PLUS, 40kW

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). 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 5 mm provides a service life of 15 years or more; the system of dissecting the air flow throughout the entire volume of the furnace, which ensures complete combustion of fuel; the system of adjusting the air flow for any type of solid fuel and combustible waste; electronic control of the forced air supply with the possibility of installing a climate thermostat and remote control functions; five years warranty on the heat exchanger; the ability to clean the grate and move the fuel during Operation (mechanical touching); the system of holding the removal of heat with flue gases, the temperature of which in the stable mode of the boiler is 90-110°C; a single fuel load is from 7-36 hours; if necessary, the Boilers are equipped with an automated fuel supply system or a brush Hopper. Control system: the design of the boiler provides for its operation together with an electronic control panel and blowing fans. The control system is based on an electronic regulator, which is designed to provide a set temperature of the coolant at the outlet of a solid fuel boiler. The principle of operation of the device is to control the fuel combustion process and the circulation of the coolant by regulating the speed of the fans that pump air into the boiler furnace, and supplying power to the circulation pump.
