Steel Gas Boilers of the CLEVER L Series

Lemax high powerful steel floor gas boilers of the CLEVER L series are THE FIRST powerful heating water boilers with an atmospheric burner of a wide range of power modulation (50/60 / 70kW -150 / 180 / 200kW) of Russian origin. Floor-mounting equipment was designed for use in heating systems operating with forced circulation, it demonstrates high efficiency with a minimum ratio of coolant to the area and mass of the heat exchanger.

Description

Description

The model range is 100 kW, 150 kW, 180 kW, 200 kW.

Operating pressure up to 6 atm.

Smooth power modulation in a ratio of 1:3, which ensures minimal load on the components of the heating system and minimizes gas consumption.

Low power consumption.

The improved systems of safety against freezing, overheating of the heat exchanger, reverse draft in the chimney, excess pressure of the coolant in the heating circuit.

Efficient operation with a minimum ratio of the volume of water in the boiler to the weight and area of the heat exchanger.

Resistance to voltage drops (180 - 245 V) and gas pressure (6-25 Mbar).

Connectivity: tank for indirect heating, sensor outdoor temperature, the circulation pump of the boiler and tank for indirect heating, thermostat for regulating the temperature of the coolant depending on the condition of the premises, the system remote control and comprehensive monitoring of the components of the heating system in Rs485 Protocol, External Fan of Lemax series models Comfort-150 and Comfort-180 (for CLEVER L150 and CLEVER L180).

Serviceability of the boiler through the use of removable lining.
