The characteristic of vacuum phase-transfer high efficient hot exchanger hot water boiler
1, safe and reliable: The pressure in the shell is always lower than the air pressure in operation.
So the shell absolutely can not explode due to bearing pressure.
2, save energy and protect environment: The heat-exchange surface is designed elabrately which make the heat efficiency up to 90%-95%. The heat preservation thermal-protective coating is superior which can effectiveluy reduce heat loss.
3, endurable: The boiler is working in the shell condition which is vacuum and have no oxigen and dirt, so the boiler can work for a much long time.
4, automatic controll burning: The boiler adopts automatic controll burner and supervisory system to reduce the workload of maintance and mangement, ande realizes the working process operated precisely.
5, all-in-one to deploy: We assembled most part of accessories before leaving the factory according to the all-in-one standard in order to make the installation conveniently and promptly
