SEC-K v4 (NP) Ventilation Interlock and Gas Isolation System for Commercial Kitchens
The SEC-K is a ventilation interlock and gas proving system for commercial kitchens with multiple in-built features which can be used where and when required to help sites meet BS6173/2020 & IGEM UP19.

Multiple in-built features
The SEC-K is a ventilation interlock system for commercial kitchens with multiple in-built features which can be used where and when required to help sites meet BS 6173/2020 & IGEM UP19.
The recently updated V4 system can monitor for carbon monoxide (CO) and carbon dioxide (CO2) out of hours so even when the panel is switched off an alarm can be raised, or ventilation switched on. This provides additional safety monitoring particularly if solid fuel appliances are installed within the kitchen.
Reliability, Safety and Flexibility
Demand-controlled ventilation fail-safe gas valve and relay checking are just some of the new developments making Medem systems continue to be the most reliable, safest and flexible available today.
