  • Interlock with ventilation using either Fan Current Sensors or Air PD Switches
  • Optional Gas Proving function
  • Control ventilation automatically based on real-time gas consumption and CO2 levels in the kitchen
  • Optical and duct heat sensors to maintain optimum ventilation rate as per DW172
  • Ventilation rates reduced when gas usage and CO2 is low to reduce energy consumption
  • Minimised heat loss via extraction by reducing the fan speeds when gas usage and CO2 are minimal
  • Pulsed output gas meter can be linked with other building systems to monitor the kitchen
  • Reduces ventilation noise levels at times of low kitchen activity
  • Clear full colour TFT display for the user info and easy calibration
  • Takes responsibility for sufficient ventilation control away from kitchen staff

Smoking barbecue causes Carbon Monoxide poisoning at Gordon Ramsay Restaurant

By Industry News, Latest News, S&S Northern

Two people, believed to be staff members, at the chef’s London House brasserie had to be assessed for suspected carbon monoxide poisoning and adjoining flats were evacuated after a carbon monoxide alarm was activated.

Two fire engines and an ambulance were called to the scene, in Battersea, South-West London. Dr Deborah Turbitt from Public Health England warned of the dangers posed by burning charcoal.
‘It is extremely dangerous to have a lit or smoldering barbecue indoors or in an enclosed space. This is because barbecues emit carbon monoxide, a poisonous gas that you can’t taste, smell or see.’

This potentially life threatening incident could have been prevented by using one of our Carbon Monoxide Detectors, which will provide an audible and visual alarm if the levels rise to a dangerous level. Our Carbon Monoxide detectors will also close the gas solenoid valve preventing further use of gas in the building until the levels reach a safe level, therefore avoiding any additional safety hazards. When using our CT1750 with a Carbon Monoxide or CO2 detector, this has the facility  to automatically increase the speed of the fans if dangerous levels are detected, even if the panel is switched to the off position. For a full range of our gas safety systems please contact S&S Northern direct or visit our website
