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 3mm 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 2 atm. Due anticorrosive coating enamel (exposure temperature 950 ° C) and treatment with inhibitory composition, the heat exchanger is protected from aggressive factors, solutions of salts and mineral oils.
- Two independently operating 820 NOVA SIT gas valves.
- Temperature regulators placed on the front panel select optimum heating conditions.
- Boiler requires no electrical power.
- A system of protection against overheating, draft interruption and soot formation.
- 3 atm. pressure isolation valve.
- Maximum efficiency provided by:
- extension of the heat exchange surface area;
- swirler device design change to delay exhaust gases to the maximum.
- The increase of primary and secondary air flow.
- You can connect a room thermostat to adjust boiler temperature to the room temperature.
- 3 years warranty.
