Used 2012 Nitrogen Unit
The Stewart & Stevenson WNT-181601 combines a 180 SCFH nitrogen vaporization and pumping system with a 600 HP fluid pumping system in a trailer-mounted package. The Stewart & Stevenson non-fired nitrogen system uses the engine (glycol/water) coolant system to pass heat from the engine and hydraulic system to the liquid nitrogen using a high-pressure heat exchanger. The fluid pumping system uses a diesel engine to drive a high-pressure piston pump through a transmission.
