Low cost gas mixers work pneumatically

Witt Gas Techniques has released low cost gas mixers that require no power supply as they are pneumatically operated, have no electrical connections and handle flows from 2 litre/min to 100m3/h.

Witt Gas Techniques' MG 25/35/45/95-2 FIX and MG 25/35/45/95-2 FLEX low cost gas mixers require no power supply The mixers are being pneumatically operated with no electrical connections and have flow capacities ranging from 2 litre/min up to maximum of 100m3/h

These gas mixers have been designed for use with all technical gases including carbon dioxide (CO2) and Nitrogen (N2) in a number of industrial applications.

The MG 25/35/45/95-2 FIX has factory pre-set tamper proof gas mixtures, whilst the gas mixture in the MG 25/35/45/95-2 FLEX is adjustable using a control knob and %-scale to provide infinitely variable gas mixture settings.

Typical applications would be the pressurisation of beverage dispensing systems, such as beer kegs as well as welding and food packaging (MAP) applications.

Features of these gas mixers include the following.

* New mixing technology patented by parent company Witt Gasetechnick, whereby no receiver is required producing both a space and cost saving, they also eliminate the need to stock costly, multiple pre-mixed gas.

* They have a high mixing accuracy better than +/-2% abs.

and are provided in a panel for wall mounting.

These mixers also have high process reliability in that they are independent of any pressure fluctuations in the gas supply.

They have a fail safe device, whereby they will shut down immediately on failure of the gas supply.

An optical alarm will alert the operator, an option is an audible alarm.
