The operating pressure of the vacuum boiler is less than one atmosphere, that is, 0.1MPa, and the design pressure is less than 0.07MPa. Therefore, the "vacuum" of a vacuum boiler is a relative pressure, not an absolute pressure.

Thanks to the pressure of the vacuum boiler below 0.07MPa, it does not belong to the scope of special equipment supervision and inspection in China, and it is simple and convenient to use without approval. The integrated operation and intelligent control during operation also do not require a special certified fireman, saving a lot of human capital.

Different from electrode boilers, vacuum boilers can be divided into gas-fired vacuum hot water boilers (vacuum hot water boilers), electric vacuum boilers (resistance boilers) and oil-fired vacuum hot water boilers. Suitable for all kinds of large complexes, office buildings, commercial buildings, hospitals and other places, can provide hot water and heating and air conditioning at the same time, is a heating boiler.

The thermal efficiency of vacuum boiler produced by our company is 94.6%, which is in a leading position and saves every point of operating cost for customers. Welcome to inquire about our environmental boiler products, 0575-82190417.
