The FRIALEN Geo Y can be fused with pipes made of PE 100, PE 100 Plus Geo CR respectively PE 100-RC of SDR stages 11 to 17.6.

SKZ Mark A 500 (SKZ HR 3.26)

Area of application

The FRIALEN Y-pieces are used for the connection of FRIALEN borehole heat exchanger pipes to be able to operate two or more circuits via a shut-off element or to quickly and efficiently cre­ate a direct connection to the heat pump. FRIALEN Y-pieces have a smooth, hydraulically optimised internal contour for optimal flow conditions.

Assembly instructions

The connection of the pipes with FRIALEN Y-pieces made by FRIALEN electro­fusion is leak-proof and lon­gitudinally strong.

The PE spigot end of the YS-pieces as well as the borehole heat exchangers- and connection pipes, made of PE 100 or PE 100 plus Geo CR respectively PE 100-RC, get prepared (removing oxide layer/cleaning), according to the general assembly instructions (see “Assembly Instructions” for “FRIALEN-Safety Fittings for house connections and distribution pipes up to d 225”) and can be used for example with a FRIALEN elbow 90°.

Many good reasons for using the FRIALEN Y-pieces:

  • 8 mm coupler extension of the Y-piece for more safety when installing coiled pipe because of long guiding- and holding zones
  • less space required thanks to compact design
  • reduces installation time thanks to integrated fusion couplers giving simultaneously processing safety
  • leak-proof, lon­gitudinally strong connection
  • exposed, fixed heating coil for direct heat transfer to the pipe
  • maximum stability through great wall thickness
  • fusion indicators for visual fusion control
  • barcode for fully automatic fusion with HDPE pipes from SDR stages 11 to 17.6, taking into consideration the ambient temperature (temperature compensation)
  • flexible use enabled due the variation of either Y-piece (3 x coupler) or YS-piece (2 x coupler,1 x spigot end)
  • additional barcode for tracing back the component part (Traceability-Coding)
  • durable batch marking
  • individual foil wrap to prevent dirtying at building site
  • touch proof electric contacts
  • small annular gap for build-up of optimum joining pressure in the fusion zone
