High Pressure LN₂ — liquid nitrogen delivered at pressure for demanding processes
High pressure LN₂ describes liquid nitrogen that is pumped or pressurised so that it can be delivered as a dense, cold stream or vaporised into high-pressure gas. REAL GAZ supplies the liquid and advises on the equipment needed to use it safely.
Typical systems combine a cryogenic storage tank, a reciprocating or centrifugal cryo-pump and a vaporiser that converts liquid to gas at the required pressure.

Design and operation reference EN 13458, ISO 21013 for pressure-relief devices on cryogenic service, PED 2014/68/EU and ISO 21029, suitable for oilfield, testing and manufacturing applications.
Safety is built into every pumped system. Transfer lines should be insulated and fitted with relief valves between closed valves so that trapped liquid cannot burst a pipe on warming. Personnel should be trained in the risks of rapid expansion, since liquid nitrogen turns into about 690 times its volume as gas. Typical working pressures run from a few bar for transfer to several hundred bar after vaporisation, depending on the pump and the end use. Customers that run mobile pumping units should discuss road access, parking position and grounding of the tanker with us before the first job, so that the set-up is quick and orderly.
🏭 Where High-Pressure LN₂ Is Used
- ⚙️ Well and pipeline services — pumped nitrogen is used to displace fluids, test pipelines and support well-intervention operations at high pressure;
- 🔬 Pressure cylinder filling — liquid is pumped and vaporised to fill banks of 200 and 300 bar cylinders much faster than compressors allow;
- 🏥 Hydrostatic and burst tests — vaporised high-pressure nitrogen provides a clean, dry medium for qualifying vessels and components;
- 🚀 Cryogenic cleaning — nitrogen jets at pressure remove coatings, flash and residues from moulded and cast parts without chemicals.
