This new generation of oil/gas transfer system is designed and built to handle media of either in liquid state or gaseous form, suitable to be used in oilfields whereas both high gas concentration and high compression ratio prevail and call for dynamic and complex transfer process. With its high internal compressing power, high throughput, high compression ratio, powerful oil/gas transfer capability and highly effective energy saving characteristics, 3DP70 has become the latest state of art transfer system for both inland and off shore oil/gas producing operations around the world.
