Steel Gas Boilers of the Premium Series 70kW - 100kW

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.

Description

Description

The model range is from 70 to 100 kW.

Maximum efficiency due to an increase in the heat exchange area and the use of an innovative design of turbulators for maximum delay of exhaust gases.

Operating pressure - up to 2 atm.

Two independently operating safety automatics 820 NOVA SIT.

Improved safety systems against overheating of the heat exchanger, interruption of traction, soot formation, boilerblowing.

An overpressure valve is installed in the heating circuit for 3 atm, which allows to compensate for errors during the installation of the heating system.

Ease of maintenance of the boiler due to the use of an easily removable top panel.

Аdvantages with automatic 820 NOVA:

The temperature regulator is located on the front panel of the boiler.

Working in conjunction with the Lemax monitoring and control device for remote monitoring and control of the gas boiler and heating system indicators through a mobile application.

Possibility of connecting a room thermostat to regulate the indoor temperature with high precision.

A soft start system that provides acoustic comfort at the time of boiler start-up.
