      Description

      The facility is aimed at heating houses, cottages and administration and accommodation buildings, equipped with forced or gravity hot water heating.

      • Lemax steel heating units of the Forward series are represented by three models: 12,5, 16 and 20 kWt.
      • Run at firm fuel: brown coal, coal, coke. Wood can be used as additional fuel. High environmental friendliness when burning fuel.
      • The compact, shock-resistant heat exchanger, with its safety being ensured by use of heat-insulating materials.
      • High-quality 4 mm special steel by the Magnitogorsk Iron and Steel Works and heat-resistant fire-bar made of high quality grey cast iron contribute to the durability of the boiler, which easily endures temperature falls and rises.
      • The heat-resistant coating of the heat exchanger and its being covered by inhibiting composition of internal cavities of the boiler increase the resistance to corrosion.
      • The boiler features high efficiency provided due to an innovative design of the combustion chamber with horizontal elements of heat selection.
      • Top charging system does not only provide comfortable charging from the bucket, but also allows uniform distribution inside the fuel bowl. For front charging system (through the door) heating units, especially the multisectional ones with a long heat exchanger uniform fuel distribution inside the fuel bowl takes extra time and effort.
      • The round flue of 140 mm convenient for connection will deliver from the necessity of adapters selection.
      • It can be equipped with the non-volatile regulator of draft (air supply).
      • The connection between the wall sides of the water jacket has been increased due to the channel bars, thus enhancing the heat exchanger resistance to shattering and increases the durability of the heating unit.
      • 3 years of postproduction quality service.
