effective in compressing gases and in some way the heart of the refinery are considered and with danesh basian company has produced a reciprocating compressor with unique features. this compressor has an advantage that it has a reciprocating compressor that compresses gas to gas , of course hydrocarbon gas, process gas twice and ten times . it makes one of the competitive advantages of this oil-free compressor is that the presence of oil in the chamber actually makes the compressor work, and it is produced according to the 118 standard with today's knowledge . volume of milk and environmental materials the concept of collection actually prevents the processing of gases and the collection of gas that today is burned in metal. the compressor is one of the members of the refinery team. the vital role in the design of this compressor is beyond reverse engineering. the compressor is not reverse engineering and we did a conceptual design. we have done a redesign, we have improved the quality of all the parts, and compared to foreign samples, its score is lower than the foreign sample, then in this c
