BoilerGuard - Plant Room Safety System

BoilerGuard - Plant Room Safety System

The BoilerGuard system is designed to meet the requirements of IGEM/ UP 2 Edition 3, IGEM/UP/11 Edition 2 and provides the complete safety solution for any plant/boiler room whether Gas or Fuel Oil is used. The BoilerGuard can work alongside a BMS or act as the main safety circuit.

This system can act as the central controller for the gas supply whist monitoring ancillary devices such as gas sensors and thermal fuses. It can also be interfaced with a BMS and interlocked with the power supply to the plant to delay start up until the gas supply is live.

With a number of useful features including being able to automatically restore the gas supply after a power failure, the BoilerGuard provides complete peace of mind and simplifies a quite often complicated safety circuit.

Basic Operation

When switched on via the key switch the BoilerGuard will check all interfaces prior to energising the gas solenoid to ensure no gas is released into a potentially unsafe environment.

The Boiler/Plant can be easily interlocked using the 230V 5A rated contact. This will not close until the gas is live, stopping appliances starting up prior to the restoration of gas
