Gas-fired vacuum phase change boiler

Van de Lee gas vacuum phase change vertical boiler

The thermal efficiency is 15% higher than that of similar products, and the service life is longer than that of similar products.

The vacuum phase change boiler is always running under negative pressure. It has no risk of explosion. The heat exchange part is independent, the pressure 1.6MPa pressure is stable, and the operation is stable.


Van de Lee gas vacuum phase change horizontal boiler

The thermal efficiency is 15% higher than that of similar products, and the service life is longer than that of similar products.

The self developed heat source cluster rotary integration energy storage and multi zone multi chamber heat transfer technology have greatly improved the thermal efficiency, and the exhaust gas temperature is about 100 degrees Celsius, which is 15% higher than that of the same kind of fuel gas boiler.


Van de Lee condensing vacuum phase change gas-fired boiler

Compared with the same product, the two side outlet temperature increased by 5 - 8 degrees, and the thermal efficiency of the same product increased by 20%.

The condensing boiler uses the two heat exchange technology to effectively absorb latent heat from the high temperature flue gas, and the exhaust gas temperature is between 30-80 degrees (the system's backwater temperature determines the exhaust gas temperature). The exhaust gas of the boiler can be made of PVC pipe or galvanized pipe, and the thermal efficiency can reach 105%.
