Merlin 3000S Gas Interlock Panel

Merlin 3000S Gas Interlock Control Panel

The Merlin 3000S system has 2 built in 0-10VDC outputs. This is designed to vary the speed of the ventilation system(s) based on either, real-time gas usage via a turbine gas meter, Carbon Dioxide (CO2) levels in the area, smoke/steam detection in the canopy using optical sensor or heat detector in the extract ductwork.

For best and most accurate results, all should be used together but any combination of the 4 sensors can be used. As the CO2 or gas usage increase in the commercial kitchen, the Merlin 3000S will increase the speed of the ventilation system to provide the perfect cooking environment.

Conversely, when only minimal gas is being used and the CO2 levels are low, the Merlin 3000S will reduce the speed of the ventilation systems, saving energy and money. The optical sensor will increase the ventilation should it detect excess smoke or steam in the canopy along with the duct mounted heat sensor to monitor excess heat in the duct.

The Merlin 3000S also carries out its duty as a traditional ventilation interlock and gas pressure proving system alongside the ventilation on demand capabilities. This allows for one ingle small control panel in the kitchen, freeing up valuable real estate on the kitchen walls.

Full compliance with:

• BS6173:2009
• IGEM/UP19
• DW17
• CIBSE TM50
• HSE Catering Sheet 26

Feaures

• Interlock with ventilation using wither Fan Current Sensors or Air PD Switches
• Optional Gas Proving function
• Controls ventilation automatically based on real-time gas consumption and CO2 levels in the kitchen
• Uses optical and duct heat sensors to maintain optimum ventilation rate as per DW172
• Reduces ventilation rate when gas usage and CO2 is low to reduce energy consumption
• Minimises heat loss via extraction by reducing the fan speeds when gas usage and CO2 is 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 user info and easy calibration
• Takes responsibility for sufficient ventilation control away from kitchen staff
• Maintains 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
• Fully suitable for kitchens with solid fuel appliances
• Can be linked to remote knock-off buttons, fire alarm and BMS
• Covered by the S&S Northern 3 year warranty
