This is a three stage compressor package custom designed to client specific requirements like having (2) bolt-on skids for pipework and valves placed under grating, scrubbers and discharge coalescer; that are to be bolt mounted on the main skid at site. Other special options was to supply a diaphragm pneumatic pump for filling the oil day tanks automatically and having besides the main unit control panel an Ex-e box with HMI for control installed on skid. We supplied three identical units.
