Ensures cellar’s safe from CO2

The Selvapiana winery in Tuscany is
using Crowcon’s CellarSafe and
Xgard fixed CO2 gas detectors to
protect workers in the winery’s cellars.

CO2 is a by-product of the
fermentation process and, because it
is heavier than air, it can spill out of
fermenting tanks and sink to the
winery floor, where it forms deadly,
invisible pockets. Workers cleaning
grape skins out of fermenting tanks
are also in danger, as any remaining
CO2 can deplete oxygen in the tanks.

Two CellarSafe CO2 detectors and
one Xgard CO2 detector are installed
in the winery’s cellars. The CellarSafe
units provide two levels of
protection: Firstly, if CO2
concentrations exceed a threshold,
extractor fans are triggered;
secondly, an 82dB alarm is triggered
to warn workers to vacate the cellar.

The detector is linked to a control
unit that constantly displays ambient
CO2 levels on a computer screen in
the control room.
