Introducing the Merlin 3000S

By Industry News, Latest News, S&S Northern

The wait is over and we are pleased to reveal our brand new product, the Merlin 3000S. The Merlin 3000S is an energy saving system designed specifically for commercial kitchens. The system acts as an interlock between ventilation and the gas solenoid valve, while also varying the speed of the ventilation via 0-10VDC outputs.

Advantages of the Merlin 3000S include:

  • Full compliance with: BS6173:2009 / IGEM/UP19 / DW172 / CIBSE TM50
  • Control ventilation automatically based on real-time gas consumption and CO2 levels in the kitchen
  • 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
  • Maintains the air balance between supply and extract ventilation creating a negative pressure in the kitchen to control cooking odours
  • Will accept Methane, LPG and CO detectors
  • Can be linked to remote knock-off buttons, fire alarm and BMS
  • Covered by the S&S Northern 3 year warranty

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.

ATL Commercial Kitchens Ltd has developed a fully operational demonstration commercial kitchen which showcases energy saving kitchen products to customers.

One of the product the company is showcasing is S&S Northern’s new Merlin CT3000E which monitors the electrical consumption being used from equipment under the canopy alongside CO2 levels within the commercial kitchen. When the Merlin 3000E receives a signal via the electricity or CO2, it adjusts the fan speed accordingly. This results in a huge cost saving for commercial kitchens as fans do not then need to be run at full speed all the time whilst still maintaining a safe and comfortable environment for the kitchen staff.

ATL, based in Hull, specialises in commercial catering and building services.  The company helps professional kitchen staff to choose the right equipment for their kitchen.  Their services include planning, design, installation and completion.

Ashley Stephenson and Lee Dempsey at ATL Commercial KitchensAshley Stephenson Director of ATL says, “We have developed the demonstration kitchen in order to showcase our manufacturer’s equipment and the possibilities within ventilation controls and energy efficiency. Many people do not realise that the commercial kitchen environment can be one of the major contributors to wasted energy within a commercial building.  This is really clearly explained within the Chartered Institute of Building Services Engineers (CIBSE), document TM150 2009”.

Lee Dempsey, Sales Manager at S&S Northern says, “We were delighted to partner up with ATL and showcase our newest energy saving product to ATL’s customers.  

We are sure customers will be impressed with what it offers as we know that the payback period for the Merlin CT3000E is just two years.”

Merlin CT3000EThe Merlin CT3000E is a Ventilation Interlock and Electric isolation panel with build-in analogue output signal to regulate the speed of the fans accordingly to the electrical power consumption.  The system comprises a control panel and AC current sensor(s). The Merlin CT3000E can receive connections from remote emergency shut-off buttons and gas detector. It also can be integrated with a BMS and fire alarm.
