Technical description

Main functions

The WPC is a pressure generator for performing proof pressure and alternating pressure tests on large capacity water heater pressure vessels (EN 12897).

These tests can be performed under water circulation, with temperature management.

The products tested with this bench :

pressure vessels (e.g. water heaters)
pumps and pump bodies
pipes
valves and valve bodies

Operating mode

The products to be tested are connected to the generator via hoses, which are placed next to the test bench. The generator is connected to a water supply (city water) and to the drain.

Once the products are connected, the generator manages :

the filling of the products
the generation of the test pressure according to a programmable profile
water circulation
maintaining the temperature of the test water thanks to an integrated heater.

The pressure generator is compact and mounted on wheels, which allows it to be easily moved close to the product to be tested.

The generator is controlled by a PC equipped with test software that allows easy generation of test programs, storage of these programs, real-time display of measurements, saving of results files and editing of reports.
