Atlas Copco was originally contacted for its proposals for a compressed air supply by process engineering consultants Otto Simon Ltd, who were assisting Ascot Environmental with the project. The Dargavel installation now comprises two network-linked GA37+ 8bar, full-feature, oil-injected rotary screw compressors with integrated air treatment and downstream filtration, together with an OSC600 oil/water condensate separator, an EWD 330 electronic condensate drain, a 3,000 litre air receiver, plus an ES4i integrated sequence controller.
