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 «Premium». The heat exchanger has a cylindrical shape, which allows the boiler to work in closed systems with the operating pressure of 1 atm maximum (for «Premium»-7,5 - «Premium»-10) and of 3 atm maximum (for «Premium»-12,5 - «Premium»-60). 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.

  • Extended power range from 7,5 to 60 kW.
  • The boiler does not require connection to the electric mains.
  • Equipped with original components of gas-burning device and gas valve produced by Italian concern «SIT», as well as with «POLIDORO» injection micro-flame burners.
  • Protection against overheating, traction interruption, soot formation, and blowing of the boiler.
  • Easy boiler cleaning through the use of a removable top panel.
  • Enhanced security protection system (overheating sensor mounted on heat exchanger).
  • Maximum efficiency due to:
    • increased heat-transfer area;
    • changes of baffle construction for a maximum delay of exhaust gases.
  • Increase of the primary and secondary air flows.
  • DHW domestic hot water.
  • LPG operation.
  • 3 years warranty.
