Horizontal steam boilers of the WDR series have a separate
construction of boiler and switch cabinet to prevent the ageing of
electrical components when heating and impairing the service life.
With high -quality electric heating pipes in Germany and abroad,
the normal service life can be 20.000 hours. All electrical
components have CE and CCC certification to ensure product safety
and durability. The heat efficiency of the boiler is close to 99%.
It runs smoothly, clean and does not emit nitrogen oxides. O
Atmosphere and meets environmental requirements.
Product Features
1. Clean and convenient:
The installation of more ash compensation holes on the boiler can
effectively and promptly clean the ashes, avoid operating obstacles
and the decline in thermal efficiency due to the accumulation of
boiler ash, and ensure the stability of the boiler load.
2. High security:
Power water is controlled by the computer and supplied
automatically. Equipped with water deficiency, protection of
overload and other devices, safe and reliable.
3. Life and duration:
Excellent professional design, advanced production technology and
rigorous boiler quality control are the guarantee of every quality
of the boiler. The normal service life of the boiler is more than
twenty years.
4. Environmental protection and low noise:
The original exhaust gas emission of the boiler is low and the tail
of the boiler is equipped with an efficient dust collector and a
low noise fan. The emission of flue gas meets national
environmental protection requirements.
5. Manufacturing specifications:
Each part of the boiler is produced in accordance with national and
international standards (ISO).All production connections strictly
follow advanced production technology to ensure product quality
reliability.
6. Good service:
Technical services, installation guide, regular and irregular
visits to users, at any time to provide users with quality and
perfect services, so that users can be safe and comfortable to
purchase.
