Description

Wall-hung Boiler Heat Exchanger - B1、B2、B3

1. Independent R&D, design and manufacture;

2. In strict accordance with the European standard EN-AC43000, silicon-aluminum alloy materials are used;

3. The thermal conductivity of silicon-aluminum alloy is high (8 to 12 times that of stainless steel), and the cast product has strong corrosion resistance and long service life;

4. Using excellent casting technology, one-time molding, modular combination, compact structure, high density, high strength, and more convenient maintenance, disassembly and replacement;

5. Unique waterway design, fully water-cooled structure, small resistance, fast heat conduction, and stronger heat absorption;

6. The combustion chamber is fully water-cooled, with parallel water channels and low water flow resistance. The flue system heat exchange and condensation integration rib column combination greatly increases the heat conduction area;

7. The reverse heat exchange between flue gas and water medium has better condensation effect and lower exhaust temperature. Compared with the current traditional heat exchanger, it can save energy by more than 30%;

8. The power ranges from 20KW to 2800KW, and various models meet different needs of users.
