Kermi about liNear

Design service is very important for Kermi.  This is why the cooperation with liNear has existed since the mid 90s. Developments in the field of radiator and panel heating dimensioning were implemented together.

Kermi was one of the first manufacturers to offer CAD symbol libraries and has been a liNear marketing cooperation partner for many years.
