Phase change vacuum boiler's half bottom is Similar with ordinary boiler, 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 absolutory DNA 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.

Safe and reliable:Phase Change Vacuum Boiler 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 it can't be an explosion.

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.

High thermal efficiency:With three-pass structure, the second return pipe with threaded smoke pipe , heat transfer enhancement, the third return pipe using the smooth pipe, reduce flue gas flow resistance. Large heating surface, low temperature heat medium, large temperature difference, the exhaust gas temperature is low. The 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.

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.

Accurate control :According to outside load change, automatic adjusting operation, hot water temperature can be set freely between 20 - 90 ℃, set after the unit can automatically adjust the temperature, to ensure a constant temperature.

Highly Standard Configuration :Boiler combustion and control system components adopt imported high quality accessories,Brand of burner: Weishaupt (Germany),Baltur ,RIELLO (Italy).SEMIENS Touch Panel ,PLC .Reliable performance and low operation maintenance cost.For its high thermal efficiency, save the fuel;Fully automatic operation, do not need professional operation personnel, save labor cost;Without annual inspection, maintenance and management cost is low.

Easy to install:Units with built-in heat exchanger, system not need to be equipped with water treatment, heat exchangers and other external devices, simply connect the external piping can be used, greatly reducing installation requirements and fees.

Straight-tube heat exchangers, easy maintenance:Vacuum hot water unit of internal heat exchanger, straight tube bundle of heat exchange tube of stainless steel tube, even if the unit after a long run there is dirt inside the pipe, open water chamber head on both ends, for simple mechanical wash with brush.

Comply with environmental requirements:Complete combustion of fuel, low dust emissions;Secondary combustion, effectively inhibited NOX generation;Burning low noise, low back pressure in chamber.

1.Boiler Proper Introduction

With the best quality of Q235 panel and 20# tubular stock for boiler proper.The advantage is for it's big boiler furnace,which with large heating area ,small volume,compact structure and fast heat up Characters. And also with Negative pressure evaporation chamber,it can be more Steady and Reliability.Because of its huge vacuum evaporation chamber, all kinds of heat exchanger can be customization.Normally the horizontal boiler working with straight pipe , which with both elliptical ,easy to wash and maintain.

2.Manufacturing and structure of heat exchanger

Heat exchanger is made of stainless steel material, in pipe bundle type into negative pressure evaporation is connected with flange at both ends. advantages: It is not only convenient to remove and replace, but also easy to maintain clean and not easy to get corrosion .

3.Automatic Control

The control part selects the advanced automatic controller,which can automatic detects boiler water temperature, Hot water temperature and fault in burner and internal furnace . In addition ,the burning time can be set by the program.What's more, it can adjust automatically combustion process,correctly according to the change of load, to reduce start and stop times caused by the change of the load.This ensures boiler run normally, and reduce heat loss.

4.Combustion Equipment

On account of the special design of phase change vacuum boiler, varies importing and domestic fuel&gas burner can be installed though special installation board according the fuel and clients 'requirements.
