Steel Gas Boilers of CLEVER Series

In accordance with European standard EN 10130: 2006, the American standard ASTM A 1011 and Russian GOST 16523-97 and GOST 9045-93. 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 20-50 kW.

Operating pressure up to 3 atm.

Improved safety systems against overheating of the heat exchanger, interruption of traction, soot formation, freezing of the boiler

Work in a heating system with forced and natural circulation of the coolant.

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

Continuous smooth power modulation that minimizes energy consumption.

Optional connection of remote interior comfort monitoring and control devices (Android and IOS) using the integrated ModBus protocol or relay-type contacts.

It is resistant to voltage drops (180 - 245 V) and gas pressure (6 - 25 mbar).

Low noise level.

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