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.

Whitepapers

  Future proofing the DHC network PDF 612 KB Preview Download Mail

During the District Heating and Cooling Symposium 2010 in Tallinn Thermaflex presented 5 papers addressing the benefits of flexible pipe systems and tailored prefabricated solutions over the entire network lifetime, exemplified by the pre-insulated piping system Flexalen 600. Since that time Thermaflex achieved a global acceptance of the introduced solutions as they have been successfully implemented in numerous District Heating and Cooling network applications all over the world. This formed the basis for further developments since 2010. Production facilities have been up-scaled to meet an increasing demand and quality level. The cooperation of R&D with key stakeholders focused on responding to their challenges with new and improved solutions.

  Verification of heat loss measurements PDF 328 KB Preview Download Mail

Heat loss tests are performed on different samples of the Thermaflex Flexalen 600 series and one ST-PUR-PE sample with the Thermaflex heat loss equipment and at two recognized test facilities, both using different test methods. The results of the institute using the same, guarded end method comply with the Thermaflex heat loss equipment’s results. The results of the institute using the calculated end method differ considerably from the Thermaflex results. In this paper a comparison of these methods and results and a verification of the Thermaflex heat loss equipment is given.
