Recognized as the boiler which boiler explosion never occurs, vacuum hot water boiler for sale in ZG Boiler can be multiple used and it can supply different temperature hot water for various purpose. Vacuum hot water boiler's half bottom is similar with ordinary boiler which combined with combustion chamber and heat transfer tubes. The inner part is the media hot water, and rest empty part is air, with an U tube works as heat exchanger. In the vacuum condition, as it runs in the condition of negative pressure, it absolutely ensures the safety. The media of hot water with no increase, reduce, in or out, it transfers the power with U tube and heat exchange. It’s completely deoxygenated pure water, with no corrosion or fouling, with a long life-span of more than 20 years. In conclusion, with this characteristic, It’s a tendency to replace of the traditional boiler and shell type boiler.

Vacuum Hot Water Boiler Features

1. Safe and Reliable

Because of its medium circulation system pressure below the atmospheric pressure, Unit running internal absolute pressure is 0.02 ~ 0.08 MPa, Units in the vacuum state, so that vacuum hot water boiler can't be an explosion.

2. Long Service Life

Scaling does not occur inside the boiler to increase the life of the boiler, the boiler life is generally 1.5 to 2 times. Heat exchanger made of stainless steel tube manufacturing part, resistant to corrosion, the design life of more than 20 years.

3. High Thermal Efficiency

Adopt three return pass structure and unique structure of the wet back to combustion chamber structure, to abandon the traditional fire-resistant insulation materials, significantly reducing the unit before the smoke room temperature, plus the machine uses high-quality aluminum silicate insulation, making the unit down to limit heat loss, overall thermal efficiency of up to 92 % or more. Never furnace fouling, can run for many years to maintain high efficiency.

4. Multiple Use

A boiler (Hot water unit)can configure multiple heat exchanger, different temperature, different uses of hot water , such as central air conditioning, sanitary hot water, process water, etc.
