- Product range: 7.5 to 30 kW.
- The boiler does not require power supply.
- Operating pressure: 12.5 to 30 kW: up to 3 atm; 7.5 to 10 kW: up to 1 atm.
- Equipped with original gas-burner components and automatic safety controls as well as with the micro-flame injector burner.
- The heat exchanger is made of high-quality 2 mm thick steel compliant with the European standard EN 10130:2006, the American standard ASTM A 1011, and the Russian standards GOST 16523-97 and GOST 9045-93.
- Maximum efficiency thanks to an increased heat-exchanging area and utilisation of the innovative structure of the turbulence rings for maximum retention of effluent gases.
- Corrosion-proof enamel coating (operating temperature up to 950°C) and inhibitive composition coating protect the heat exchanger from aggressive factors and saline solutions.
- Has a system of protection from draught loss, sooting, and blowout.
- Stable operation with insufficiently insulated chimneys.
- Affordable price while maintaining efficiency parameters thanks to the unification of equipment elements, standardisation of units, and robot automation of the manufacturing processes.
- Simple maintenance of the boiler thanks to an easily removable top panel.
