In accordance with European standard EN 10130: 2006, the American standard ASTM A 1011 and Russian GOST 16523-97 and GOST 9045-93 we use stainless steel 2mm thick grade DC01in production of «Lemax» boilers series «Clever». The heat exchanger has a cylindrical shape, which allows the boiler to work in closed systems with the operating pressure of 2 atm. Due anticorrosive coating enamel «CERTA» (exposure temperature 750 ° C) and treatment with inhibitory composition, the heat exchanger is protected from aggressive factors, solutions of salts and mineral oils.

  • Wide model range: 20, 30, 40, and 55 kW.
  • Equipped with original components of gas burner units and SIT gas valve, as well as POLIDORO injection microflame burner.
  • Used in the heating system with forced and natural coolant circulation.
  • Efficient operation with minimal ratio of the boiler water capacity to the heat exchanger’s weight and area.
  • Continuous smooth power modulation.
  • Possible connection of:
    • Indirect heating tanks;
    • Thermostats (chronothermostats) to control the boiler’s temperature relating the indoor temperature;
    • Remote home controlling systems (Android and IOS);
    • Outdoor temperature sensors;
    • External fan «Lemax» for forced rejection of exhaust gases;
    • DHW and heating system pumps.
  • Systems of protection against overheating, draft interruption and freezing.
  • Resistant to voltage variations (180 - 245 volt) and gas pressure (6-25 mbar).
  • LPG operation.
  • Low noise.
  • 2 years warranty.
