Because the vapor is - water heat exchanger, the entire heat exchanger coil is surrounded by a negative pressure saturated steam, in the operating state the humid air, heat transfer efficiency is much higher than the water - water heat exchanger. Therefore, a smaller volume of the vacuum boiler, higher efficiency, less room for better reflects the superiority of properties. And because the heat also makes soft drinks shorter warm-up time, saving operating costs.

Box Group in their own development, bearing in mind the social responsibility, personally, set an example, to carry forward traditional Chinese virtues. We hope that through this way, to get more attention of the community. We work together to build a healthy growth of childhood for the children, to give them a future full of faith!

(2) fuel (gas ) vacuum phase change boilers, such as vacuum phase change boilers, adopt imported burners, which have high combustion efficiency, low noise and exhaust gas emissions. Internal use of stainless steel exchanger, on the one hand to ensure high heat transfer efficiency, on the other hand, to ensure clean water quality. At the same time, the smoke tube is equipped with spiral spoiler to improve the heat transfer efficiency and reduce the operation cost. In addition, it adopts a square structure, boiler and heat exchanger designed as one, making its structure compact and small shape beauty. Through the above classification of vacuum phase change boilers, and the description of the different types of The characteristics, so that everyone to its relevant knowledge to achieve a number of.

Second, the overall structural design of the vacuum hot water boiler is more scientific and rational, has a smaller overall footprint advantages in the boiler room building can greatly reduce floor space, a furnace body heat exchange can effectively shorten the warm-up period and reduce energy waste.
