Blauberg SIL-1750 Gas Proving & Interlock System
For Real Flame Commercial Kitchens | BS 6173 Compliant Gas Safety Control
The Blauberg SIL-1750 is a high-performance gas proving and ventilation interlock system designed specifically for commercial kitchens using real flame appliances, such as open gas burners, grills, charbroilers, and wok stations.
Fully compliant with British Standard BS 6173, the SIL-1750 ensures that gas is only supplied when both ventilation and gas pressure conditions are safe. It actively performs gas pressure proving at startup, shutting down the gas valve if any leaks or faults are detected, protecting life, property, and compliance integrity in flame-based cooking environments.
This advanced controller is ideal for schools, restaurants, and food-service sites where real flame appliances demand a higher level of gas safety and risk mitigation.
Key Features:
- Complies with BS 6173:2009 for real flame commercial gas appliances.
- Integrated gas pressure proving with adjustable fill and prove times.
- Compatible with CO, CO₂ and temperature sensors for enhanced monitoring.
- Interlocks with both supply and extract fans using PD or current switches.
- Volt-free outputs for BMS and fire alarm integration.
- Emergency shut-off button (local and remote-ready).
- 0–10V analog outputs for fan speed control.
- LED status for proving, pressure, fire, gas on/off, sensor alarms and fan faults.
- Suitable for gas interlock and gas detection combined systems.
How It Works
At startup, the SIL-1750 checks gas line integrity using a pressure sensor fitted downstream of the gas solenoid valve. If the system detects a leak or if incoming pressure is below the minimum threshold, the gas valve remains closed and the system enters fault mode.
Once proving is successful, the gas supply is enabled only if fans are operating and all other connected safety sensors (CO, CO₂, temperature) report safe conditions. Any fan failure or alarm condition during operation will automatically shut off gas and signal an alert.
Optimised for Real Flame Environments:
- Open flame gas burners.
- Commercial grills and chargrills.
- Wok stations and tandoori ovens.
- Solid fuel or mixed appliance kitchens.
Its combination of gas proving, ventilation interlock and sensor integration makes it one of the most robust safety controllers on the market.
Safety and Integration Features:
- Connects to fire alarm panels to shut off gas during evacuation.
- Accepts signal from emergency shut-off buttons (manual or remote).
- Interfaces with Building Management Systems (BMS).
- Monitors CO/CO₂ levels and reacts to poor air quality or elevated temperatures.
- Regulates fan speed automatically in response to alarm triggers.
Ideal Applications
- Commercial kitchens with real flame appliances.
- School and university canteens.
- Restaurants, hotels, and kitchens.
- Catering environments with open burners and solid fuel stoves.
- Sites requiring gas pressure proving and full system interlocking.
