Gas pressure proving, bench electrical and water isolation system

GPPS-Ti, a multiple service isolation system that allows individual control of bench gas, electricity and water supplies and has been designed primarily for use in school laboratories.

The three services can be individually turned on and off using the tactile buttons on the panel with overall secure isolation provided by the main key switch.

Equipped with a LCD, the system very easy to use. The LCD displays clear messages giving real information rather than just LED indications.

As with all our gas pressure proving systems it employs our patented technology to measure pressure differential across the solenoid valve when performing a downstream integrity check. This method stops nuisance tripping of the gas supply.

An auto-stop timer is incorporated to help prevent unauthorised use of the gas out of hours.

From within the panel the engineer has several “engineer functions” which can be used to aid in the setup of the system – such as displaying in real time both the inlet and outlet pressure at the gas valve (mbar) and the ability to power the valve at a button press, its with functions like these that for example a “valve let by indication” check be preformed with ease

    5 Year Warranty

    Medem’s industry leading five-year warranty is a demonstration of the company’s confidence in the quality and design of our products.

    This applies to the main panels and sender units, gas detectors carry a two year warranty.

    Where we commission an installed system the warranty is extended from five to ten years. At the time of commissioning photos and gas pressure readings are recorded along with other relevent details of the installation. A 24 hour help line number and serial number is attached with the panel and all details are then entered on to the Medem database.
