Description

General Information
We produce and distribute thermal solar collectors using the latest technologies and applying substantial quality systems. And we are the one of a few companies in China currently,which can adapt integral encapsulation without water leakage and with a robust construction. This offers us the possibility to obtain better quality in producing our collectors guaranteeing the best relationship between quality and price in the market.

The DEVOTION solar collectors will generate hot water quickly and efficiently. Under normal residential use, it will operate between 60ºC and 70ºC. However, the temperature can exceed this and under certain circumstances may be as high as 95ºC. This can occur during prolonged periods of direct sunlight and particularly in summer or long periods of reduced water usage. Extreme care should be taken in this case.
