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. 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.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;
- Cordless home controlling systems (Android and IOS);
- Outdoor temperature sensors;
- Lemaxу turbo nozzles 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 - 230 volt) and gas pressure (6-25 mbar).
- Switch to condensed gas.
- Low noise.
-
2 years warranty.
