Hot and Cold Water Recycling Tester (Pipe Test).

The system is used to evaluate the function of hot and cold water-pipes; (PP, PE-X, PVC-C, PB) under a certain pressure for 5000 cycles.

A test assembly of pipes and fittings is subjected to temperature cycling by the passage of water under pressure using hot and cold water alternately for a specified number of cycles.

While being subjected to temperature cycling parts of the assembly of pipes and fittings are maintained under tensile stress and/or flexural strain by the use of static clamps.

During and after the test the assembly is monitored for signs of leakage.

The tester complies with the following standards: ISO 10508, EN 12293, ISO 15874, ISO15875, ISO 15876 and ISO15877.


  • Unique Pressure Control System. A full-digital pressure control system effectively prevents the water pressure from fluctuating with the increase of both temperature and time. No water hammer phenomenon appears during the alternation between cold and hot water.
  • Unique Liquid Controlling System. Alternation time between cold and hot water is less than 1 min.
  • Energy Saving Design. The control system starts the hot and cold water return valve automatically according to the water temperature. If the hot/clod cycling system starts, the hot/cold water will return to the hot/cold water reservoir, thus saving energy.
  • Safety Design. The unit has a reliable safeguard and liquid level measuring device to ensure that the tester will be turned off if the test fails or if the piping system bursts. Transparency of tank body combines safety and easy of observation.
  • Environmental Performance. An acoustic treatment device reduces noise significantly.
