CLDR Series electric hot water boiler is a kind of high thermal efficiency and environmental protect boiler. The thermal efficiency reaches as high as 99%, and there is no NOx released to the air. The electrical control cabinet is separate from boiler body, which will not affect the boiler’s working life because of the aging of the electrical elements. The electric steam boiler adopts high quality electrical heated tube, work for about 20000 hours. It uses stainless steel electric heating tubes has high compression strength, the working life is 5~10 times longer than the common tubes.
The series electric heating hot water boiler is widely used for hospital, hotel, school, residence community, villadom, swimming pool, bath center, etc. Compare with the other traditional boiler, it is environmental protection, more convenient and noiselessness.
1. High Quality Assurance
1) Zhongding Boiler owns a professional design engineer team, before manufacturing, every boiler design drawing will be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) Nondestructive testing will be done to ensure the welding quality, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) Hydrostatic test will be done to ensure the leakproofness and strength of boiler pressure parts, generally, the testing pressure is 12.5 times of rated working pressure.
6) All the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international quality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
