GPPS-evo

The GPPS-evo is a laboratory gas pressure proving system with the ability to monitor up to four gas sensors.

The gas pressure proving is by Medem’s patented method of dynamically measuring the pressure differential across the solenoid valve when performing a downstream integrity check. This method stops nuisance tripping of the gas supply. The addition of the LCD makes this system very easy to use providing clear messages giving real information rather than just LED indications.

Flexibility
The GPPS-evo is designed to perform a downstream integrity check of pipework and appliances which could be left open to atmosphere, such as a laboratory.

In-line with the updated legislation of BB101 and IGEM/UP11/Edition 3 the system can also monitor the CO2 level when fitted with a Medem detector displaying the PPM.

CO2 is considered a primary indicator of air quality, with the latest legislation setting maximum limits for levels within educational facilities.

Carbon Monoxide, Natural Gas and Oxygen depletion detectors can also be monitored.

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

There are several ‘engineer functions’ which can be used to aid in the set-up of the system.

A let by and a dynamic pressure loss reading can be viewed by the engineer using the push buttons on the circuit board or facia ‘Power’ button. The dynamic gas pressure readouts displayed on the LCD indicating the pressure on both sides of the valve.

The carbon dioxide PPM levels can be seen by pressing the ‘Alert’ button on the panel fascia.

All our products come with a 5-year warranty
Medem’s industry leading five-year warranty is a demonstration of the company’s confidence in the quality and design of its products.
This applies to the main panels and sender units, gas detectors carry a 2-year warranty.

Why not let us install your system and receive a 10-year Warranty?
Where we’ve commissioned 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 relevant details of the installation. A 24-hour helpline number and the serial number is attached with the panel and all details are then entered on to the Medem database.

Alarm Types

Fixed low and high alarm peak levels, high alarm activation will latch and isolate the connected gas valve.

Peak Alarms

Methane/Natural Gas (CH4) & Propane (C3H8)
• 5% low alarm
• 10% high alarm

Carbon Monoxide (CO)
• 20PPM Low Alarm
• 30PPM High Alarm

Carbon Dioxide (CO2)
• 2800PPM Low Alarm

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 panel; 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 relevant details of the installation. A 24-hour helpline number and the serial number is attached with the panel and all details are then entered on to the Medem database.

Service

The panel and sensors must be re-commissioned and tested every 12 months as a minimum but with consideration of every 6 months dependant on gas type and environment.

Medem offers cost-effective yearly service plan options which include detector exchange to assist in service budgeting.
