Description

Description

The model range is from 7,5 to 50 kW.

Operating pressure: from 12,5 to 50 kW - up to 3 atm., from 7,5 to 10 kW - up to 1 atm.

Advanced safety systems against overheating of the heat exchanger, interruption of traction, soot formation, and blowing out of the boiler.

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

Independent heat exchanger of the hot water circuit minimizes the cost of annual maintenance, provides temperature stability in the DHW circuit and has a longer service life compared to a bi-thermal heat exchanger.

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 Lemax 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.

Possibility of connecting to a vertical or horizontal chimney.

Convenience of cleaning the boiler without disconnecting from the chimney due to the use of removable lining covers and a weight stabilizer.

Extended range of boiler operating voltage ensures stable operation in power grids with high and low voltage (186 - 245 v).

The heat exchange area was increased by 20% and the number of smoke channels was increased by 2,5 times to ensure the maximum possible efficiency at the lowest cost.

Possibility of connecting any relay room thermostat, with which you can have a comfortable temperature in the room regardless of changes the outside conditions.
