Both vacuum hot water boilers and vacuum boilers take advantage of the physical property that the boiling point of water decreases as the pressure decreases. Its working pressure is lower than one atmospheric pressure, <0.07MPa, so it does not belong to special equipment, and there is no need to report for approval and inspection when using.

The thermal efficiency of ZWNS vacuum boiler produced by our company is as high as 94.6%, ranking among the best, which can save huge operating costs for users. At the same time, the front smoke box and the furnace are equipped with a access port, which is convenient for daily maintenance.

As a heating boiler manufacturer, our vacuum boiler factory is a complete set of equipment, after arriving at the site can immediately take over the smoke pipe, natural gas pipeline, etc., saving a lot of construction time.

In addition to the company's existing electrode boilers (including submerged electrode boilers, high-pressure electrode boilers), steam boilers, low nitrogen boilers and other products, vacuum boilers also have a number of independent patents, with a strong technical guarantee. Our own after-sales service team can provide high-quality, professional and convenient after-sales service. In addition, there is a remote service cloud platform, which can be unattended to speed up our after-sales service speed and improve the quality of after-sales service.
