Product Details

Vacuum hot water boiler, which forms a sealed vacuum environment internally through pre-evacuation, followed by filling the boiler body with hot water. The heat medium water generates negative pressure steam through heating, and the heat from the condensation of the negative pressure steam heats the cold water inside the heat exchange tubes, thereby continuously providing hot water to the users. During the boiler's operation, the boiler water is only sealed within the vacuum chamber, with no entry, exit, increase, or decrease, and heat is transferred between the heat exchange tubes and the heat exchangers. Due to its ease of installation, maintenance, and environmental-friendly features, the boiler is widely popular in the market.

Vacuum hot water boilers, like conventional boilers, are composed of a combustion chamber and heat transfer tubes at the bottom. The innovative feature is that the top of the vacuum hot water boiler houses a vacuum steam chamber, equipped with a U-shaped or straight tube heat exchanger. It operates under vacuum conditions, ensuring efficient safety. Additionally, it can serve multiple purposes, providing hot water of different temperatures and uses simultaneously to meet various customer needs, thereby reducing the customer's investment in boiler costs.

Performance Advantages

Unique pulse water level detection circuit structure.

The heat exchangers are made of stainless steel, corrosion-resistant.

Boilers have versatile applications; one boiler can be equipped with multiple heat exchangers, providing hot water of different temperatures and purposes.

The vacuum hot water boiler features a compact structure and small size, saving on floor space.

Hot coal water circulates within a sealed space, with minimal loss.

The control section features an advanced controller, capable of automatically detecting both the furnace water temperature and the outlet water temperature.

The vacuum hot water boiler utilizes a three-pass structure and a unique wet-back regenerative chamber design, eliminating traditional refractory insulation materials, thus reducing the temperature of the smoke chamber in front of the unit.

Hot coal water is a high-purity water that has undergone special treatments such as softening, deoxygenation, and desalination. As a result, the internal surface of the vacuum hot water boiler does not scale or corrode, thereby extending its service life.
