An Oilfield Nitrogen pumping unit is highly sophisticated device which performs several simultaneous functions in order to convert liquid to a gas. Nitrogen unit is fed with liquid nitrogen at a temperature of -196⁰C. It then pumps the liquid nitrogen at this temperature to pressure up to 15,000 psi before it supplies heat to transform the liquid • Power up to 600 HP • DNV 2.7-1 frame • Zone II certified • Flow Rates up to 6000 scfm • Pumping pressure up to 15,000 psi
