Overview

Vacuum hot water boiler, which creates a closed vacuum environment inside by pre vacuuming, and then fills the body with hot coal water

Product Details

A vacuum hot water boiler creates a closed vacuum environment inside by pre vacuuming, and then fills the body with hot coal water. The heat medium water generates negative pressure steam through heating, and the heat generated by the condensation of negative pressure steam heats the cold water inside the heat exchange tube, continuously providing hot water to the user. During the operation of the boiler, the boiler water is only enclosed in the vacuum chamber, without entering, exiting, increasing, or decreasing, and heat is transferred between the heat transfer tubes and the heat exchanger. Boilers are widely popular in the market due to their convenient installation, maintenance, environmental protection, and energy-saving features.

Like other ordinary boilers, the lower part of a vacuum hot water boiler is composed of a combustion chamber and heat transfer tubes. The difference is that the upper part of a vacuum hot water boiler is a vacuum steam chamber, in which a U-shaped or straight tube heat exchanger is inserted. It operates under negative pressure and is absolutely safe. At the same time, it can also be used for multiple purposes, providing customers with hot water of different temperatures and purposes at the same time, meeting their various needs and reducing their investment in boiler costs.

Performance characteristics:

The unique pulse water level detection circuit structure ensures reliable performance.

The heat exchanger is made of excellent 304 stainless steel, which is corrosion-resistant.

Boilers have multiple uses, and one boiler can be equipped with multiple heat exchangers to supply hot water of different temperatures and purposes.

The vacuum hot water boiler has a compact structure, small volume, and saves floor space.

Hot coal water circulates in a closed space with minimal loss.

The control part uses advanced controllers that can automatically detect the temperature of the boiler water and the outlet water.

The vacuum hot water boiler adopts a three return structure and a unique wet back combustion chamber structure, which abandons traditional refractory insulation materials and reducesThe temperature in the front smoke chamber of the unit has been lowered.

Hot coal water is high-purity water that has undergone special treatments such as softening, deoxygenation, and desalination. Therefore, the interior of vacuum hot water boilers does not scale or corrode, increasing their service life.
