Haffmans OGM Ultrapure
When CO2 is recovered from the fermentation process, the gas is liquefied so that non-condensable gases – O2 and N2 – can be removed. During N2 generation the residual quantity of O2 is continuously monitored to assure that the N2 produced has a consistent high purity. During both of these processes the in-line O2 Gehaltemeter, type OGM, measures the O2 content of ultrapure gases and provides a key parameter for an efficient and economical operation of CO2 recovery.
The OGM uses optical technology that is not sensitive to organic substances and
humidity to measure O2. It provides greatly improved response times compared to
traditional O2 measuring devices and doesn’t require frequent calibration which
reduces downtime and labor cost.
The user-friendly control unit can be supplied in either field or panel mounted
versions and a maximum of two O2 probes can be connected to each control unit.
