Introduction

Vacuum hot water boiler operates under negative pressure and has multiple protection functions. It is safe and reliable and never explodes. The SU304 stainless steel tube heat exchanger has high heat transfer efficiency, low heat loss and low exhaust gas temperature.

Boiler Characteristics:

1. Safety: There is no danger of expansion, explosion or rupture during negative pressure operation;

2. Long service life: the heat medium water heat exchange system is used, there is no scaling and corrosion phenomenon, the boiler maintenance and after-sales problems are reduced, and the service life of the boiler is greatly increased;

3. Exemption from inspection products: Negative pressure operation products, the relevant state departments are exempt from inspection and supervision;

4. Small size: can be placed in the basement and roof, which is more conducive to the boiler room configuration, modular parallel connection, heating on demand;

5. Environmental protection: The measured minimum emission of NOX is 20mg/m3, which is in line with the most stringent environmental protection standards of the country;

6. Energy saving: The measured air consumption of the 0.7MW hot water boiler in one hour is <60m3, which is far lower than the industry data;

7. Numerous users: Over 5,000 projects have been reached, which can be field trips!

Main accessories of Gas/Oil fired boiler:

Features

1.Our Boiler design adopt heat transfer, flow resistance technology ,heat exchanger use high efficiency heat transfer material,it enlarged the heat-exchange unit heating surface and improved the heat transfer efficiency.

2.Safety and steady.Vacuum hot water boiler working under negative pressure

3.The medium hot water won't reudce or increase,won't go in or go out. The medium hot water is without oxygen corrosion,won't scale,it will prolong life-span 2-3 times.

4.Adopt patent technology.Boiler can supply different heat accoring to thermal requirements when outdoor temperature change.It willsupply comfortable temperature and at same time save energy ..
