Hydrotechnik UK Develop a Test Rig for Market-Leading Thermostatic Component Manufacturer

A pioneering European thermostatic element and cartridge manufacturer required a user-controlled flow and pressure demonstration testing rig, to live test a new faucet at trade shows.

As they were searching the market for a reliable and reputable test rig manufacturer, they came across Hydrotechnik UK. After speaking to our team and visiting our facilities in Nottingham, they chose us to design and build their demonstration testing rig.

The manufacturer required a purpose-built demonstration unit, so the user could control flow and pressure using a mixer tap, before displaying the hot, cold and mixed water flow temperatures. The user will reach a stable temperature on the mixed setting and then proceed to cut the cold water flow, demonstrating that the supplied faucet is able to protect the user of the appliance from scalding, by way of the internals of the tap stopping the hot water flow.

Designing and building the test rig

The demonstration test rig has been designed and built at our Nottingham facility, with the correct components specified for the purpose of the rig. For frequent demonstrations to be carried out, two large water tanks were fitted, a 50-litre and a 32-litre capacity water tank. Additionally, a pump enabled water to be pumped from the tank to the drains at the end of each demonstration. For easy maneuverability between shows, we have installed flight-case-style handles.

Finally, the pumps are enclosed and dampening feet, flexible hoses, and composite material behind the chassis mounting plate has meant that vibration and noise have been kept to a minimum.


For simplicity of use, all the main components of the rig can be controlled from the breaker box. E.g., increasing the temperature of the water, starting/stopping the pump and controlling the displays. The main LED displays are placed at the top of the unit to maximise visibility.

Testing parameters

We have integrated highly accurate Hydrotechnik pressure, flow and temperature sensors, so that the operator has the right information to hand, when carrying out a product demonstration. We have taken extra care to make sure that the temperature sensor or ‘wand' is easily accessible from the side of the unit.

Carrying out pre-determined tests

After every hydraulic and hydrostatic test rig build, the customer visits us on-site. They can carry out tests to their specifications, guaranteeing each party is happy with the test rig.

Installation & training

The demonstration test rig has been proudly displayed at different trade shows across the globe, proving popular to potential buyers looking to purchase the faucet.

All of the test rig operators have been trained by our specialists, to ensure they are able to operate the rig safely.
