HEMAB 

Sweden，Härnösand

It was installed in the base of a local energy company in 2011 and has been heating the city's district. These collectors are mainly used for urban heating in the cold winter. And in summer with high heat production, it provides up to 5% of urban hot water supply.
The long-term operation of these collectors at the base has also allowed our products to be continuously evaluated in a long-term, real outdoor environment and verified their characteristics.
