Background
The Alexandersson family, and Mr Hans Alexandersson in particular, has been active in the polymer/pipe industry for many years. He started his first company (Rörknallen AB) already in 1982 and is perceived as one of the pioneers within the Swedish GSHP industry. Hence, the family has a very long track record in the sector and their products have brought significant advantages to GSHP systems in terms of increased borehole efficiency, environmental protection and costs.
