Flexalink takes the most challenging elements of network installations – branches and connections – out of the field and onto a 100% clean and controlled factory environment where they’re carefully prepared, tested and customized to your needs. Flexalink prefabricated house connections are your guarantee for optimal and durable system performance at minimal installation time, risk and hassle.

Reliable network performance with Flexalink

Co-created in 2010 with several district heating companies, Flexalink connection technology has proved to be a real game-changer. Ideal for both heating, cooling and potable water grids, these prefabricated house connections reduce the connections needed on site by 70% compared to traditional installations. This ensures maximum system reliability as any risks of leakage and downtime as a result of faulty connections are minimized.

Record-time installation at minimal cost

Flexalink prefabricated house connections saves substantial installation time and cost compared to traditional on-site welding of branches. The ease of handling and installation – especially when dealing with crawl spaces or existing infrastructure – allows effective control of costly labor and time schedules, and overhead costs. Instead of months, the implementation of district heating networks becomes a matter of days without contract variations.

Ideal for newbuild, renovation and retrofit!

Flexalink prefabricated house connections are ideal for new networks, renovation as well as retrofit to existing infrastructure. It can be used in combination with all Flexalen 600 and Flexalen SL ranges, and fully customized upon request.
