Results Presentation

The final result is the realization of an experimental model for the screw compressor equipment powered by a piston engine fuelled with natural gas, named MOTOCOMPRESOR MCS 15.6. with the following product description.

PRODUCT DESCRIPTION

MOTOCOMPRESOR MCS 15.6.

DESCRIPTION AND USER AREA

This product realize the compression of the natural gas or extraction gas with an screw compressor powered by a thermic engine fuelled with natural gas that already exist on the functioning location ( gas compressing station, oil park etc.), entire group being electronically controlled by an automation installation. The use of the primary energy founded on the location lead to o substantial rise of energy efficiency, and also a decrease of the environmental pollution.

INCDT COMOTI Bucharest can realize such equipments at different parameters depending on users demands.
