Vacuum Hot Water Boiler Product Advantages
Vacuum Hot Water Boiler Product Advantages
1. Safe and Reliable: The vacuum phase-change boiler operates with a pressure in its fluid circulation system that is below atmospheric pressure, with an internal absolute pressure ranging from 0.02 to 0.08 MPa during operation, which places the unit in a vacuum state. Consequently, there is no risk of explosion.
2. Multi-purpose Usage: A single boiler (also known as a hot water unit) can be equipped with multiple heat exchangers to supply water at different temperatures and for various purposes such as central air conditioning, domestic hot water, and process hot water.
3. High Thermal Efficiency: With a three-pass structure, the second pass features helical flue tubes for enhanced heat transfer, while the third pass uses smooth flue tubes to effectively reduce flue gas flow resistance. The boiler has a large heating surface area, low heat medium temperature, and a significant temperature difference for heat transfer, resulting in low exhaust gas temperatures. Its unique wet-back combustion chamber design eliminates traditional refractory insulation materials, significantly reducing the front smoke chamber temperature. Coupled with high-quality silicon-aluminum insulation throughout the unit, it minimizes heat loss and achieves an overall thermal efficiency of over 92%. The absence of scaling ensures the boiler maintains high-efficiency performance over the long term.
4. Long Service Life: The non-scaling nature within the boiler enhances its service life, making it last 1.5 to 2 times longer than typical boilers. The heat exchanger section is manufactured using stainless steel pipes, which are highly corrosion-resistant, with a designed service life exceeding 20 years.
