8t gas fired vacuum boiler

In civil heating field, ZG vacuum hot water boiler has become the major force in hot water boiler market, for meeting the need of hot water, heat, and bath. ZG is always the key vacuum hot water boiler manufacturer, so we are dedicated to creating the key brand.
ZG is the largest industrial boiler supplier in China, meanwhile ZG is among the most world band GEF environment protection economical boiler manufacturing base, with the category A Boiler and Pressure Vessel License. ZG vacuum boiler including 8t gas fired vacuum hot water boiler, natural gas fired vacuum boiler, phase transition vacuum boiler. That, 8t gas fired vacuum hot water boiler is regarded as the awarded on the market.
8t gas fired vacuum hot water boiler tube hole drilling machine with three of the very most advanced precision machining technology, there's 2 internal groove processing, to make certain the exchange of copper tube vacuum performance, material blanking by advanced CNC (Computer Numerical Control) machine cutting, guarantees the precision in the process to gather, and make sure the welding quality completely from the welding quality process to ensure that no vacuum leak.
As well, the gas fired vacuum hot water boiler adopts unique overall temperature annealing process, to get rid of the welding gravity, and be sure no fatigue cracking brought on by heat-expansion and cold-contraction. heat bilges cold shrink.
