The GasVac® Cool system is specifically designed for environments where traditional gas sensors are impractical due to installation challenges or where there is a presence of various gases, both lighter and heavier than air. This system is ideal for applications such as:

Machineary Rooms:

Areas with complex equipment ayouts where gas detection is crucial but challenging.

Industrial cold storage

Large Storage facilities requiring realiable gas monitoring due to temparature variations and potential gas leaks

Walk-in freezers and cold rooms:

Locations where low temperature could affect conventional gas sensor performance

Chiller rooms

Environments where different gas types may need continuos monitoring for safety and efficiency

The GasVac® Cool system is delivered pre-programmed and pre-calibrated, facilitating immediate operation. It only requires a power connection and the attachment of a single sample line or an optional patented micropore intake module network to begin functioning. Furthermore, GasVac units are compatible with the GDS Combi addressable monitoring system, which provides advanced monitoring features, enhancing safety and operational oversight in complex environments. The full range of GDS conventional addressable safe/hazardous area gas sensors may be added directly to the Cool unit.
