Why use a KS22 V6 Trio Safestart?

Obviously, if the gas supply to a commercial kitchen or laboratory is started with gas taps open, a gas leak will occur. Crucially, the KS22 V6 protects personnel and property from damage caused by gas leaks. In addition, this unique keypad operated control panel ensures that only authorized personnel are able to start the gas supply. For commercial kitchens, the ventilation system can be initiated and checked automatically by the KS22 V6 before it allows gas to flow to any connected appliances.

What does the KS22V6 do?

Firstly the KS22 V6 automatically checks the ventilation system is turned on before allowing gas test to commence. The Trio SafeStart then checks the downstream pipework for leaks – gas taps left open. Only when it is satisfied that there are no gas taps open the electrically operated gas valve is automatically opened. All of this makes the KS22 V6 and G161 a great system for ensuring BS6173:2009 and IGEM/UP/19 compliance.

Finally, when the gas is turned on an automatic safe shutdown will occur if:

  1. Emergency stop push button is pressed (Duomo KOB21)

  2. The Air proving device detects incorrect fan operation (Duomo FP45 Current monitor, ADP10 or ADP65 air pressure switch)
  3. Low gas pressure is detected.
  4. High levels of CO2 are detected by Duomo CO2MC or CO2 Alarm.
