Description

Description

The model range is from 7,5 to 40 kW.

Boilers of the Classic series are suitable for replacing Lemax boilers of the KSG-d series without changing the connecting dimensions of the heating system.

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: from 12,5 to 40 kW - up to 3 atm, from 7,5 to 10 kW - up to 1 atm.

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

Affordable price with the preservation of efficiency parameters due to the unification of equipment elements, standardization of components and robotization of production processes.

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

The model range is from 50 to 60 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 3 atm.

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

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

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.

Work in conjunction with the External Fan of the Comfort SE series for forced exhaust gas removal in the absence of a stationary chimney.

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