Laboratory Gas Proving
There are four different systems available for
laboratories. The GPPS-L is a gas pressure
proving system designed to ensure that all gas
taps are closed before gas is made available.
The GPPS-LE can isolate the bench electricity
sockets and the GPPS-Ti isolates both the bench
electrics and the water supply.
Carbon Dioxide detection is also available on the
GPPS-L-CO2 model.
Requirement details are available in the Institute
of Gas Engineers publication IGE/UP11.

Classroom Carbon
Dioxide Monitoring

The SACO2 panel has been designed to monitor
the Carbon Dioxide level in classrooms in
accordance with Building Bulletin 101.
The panel can be used just as a monitor to advise
when the Carbon Dioxide level is high.
The system can also control mechanical
ventilation in order that the rate of air change can
be controlled depending on the occupancy level
of the room to cut heat loss in winter.

Kitchen Ventilation

The VGPS-K is designed for use in the kitchen to
ensure that any mechanical ventilation is
operating whilst the gas appliances are being
used. The system also ensures that there are no
gas leaks on the gas fuelled cooking appliances.
The system is also available as the
VGPS-K-CO2. This system monitors the Carbon
Dioxide level in the kitchen and ensures that the
ventilation rate is adequate at all times.
Refer to BS6173/2009
HSE catering sheet 23 R1 & IGE UP/1A.
