A high-pressure, skid/trailer/truck-mounted liquid nitrogen pumping unit for oilfield stimulation, fracturing, well clean‐outs, or other downhole operations, with vaporizer and full control system.
| Spec / Feature | Typical Value / Options |
|---|---|
| Discharge Pressure | Up to ~10,000–15,000 psi in many models. |
| Flow / Displacement Capacities | Values like 90K, 180K, 360K, 660K, 740K, 1000K (units often SCFH or equivalent) depending on model. |
| Mounting Style | Skid-mounted, truck-mounted, or trailer-mounted. Mobility optional. |
| Vaporizer / Cold-end System | Includes direct-fired or heat recovery vaporizer to convert liquid nitrogen to gas when needed. |
| Control System | Pressure & temperature monitors; possibly remote / wireless monitoring; safety features like overpressure protection. |
| Operating Ambient Temps | Some units designed to operate in harsh environment (-45 °C to +55 °C etc.) for both cold/high temperature. |
| Power Source | Diesel engine, electric motor; driver type depends on model. |
| Materials & Construction | Cryogenic-compatible materials, safety certified parts, robust frames. |
Ensure insulation and materials are suitable for cryogenic temps; avoid leaks.
Required vaporizer / cold-end heat input to avoid too low temperature or freezing in lines.
Keep discharge lines clean; maintain pump, valves & seals designed for liquid nitrogen applications.
Ensure safety protocols for handling LN2: protective gear, training, ventilation.
Monitor pressure/temp carefully—overpressure or rapid temperature changes can damage components.
Warranty period: typically 12 months from delivery or commissioning for defects in materials & workmanship.
Return window: 7-14 days if unit is unused, in original condition, complete with all major components.
Defects/claims must include photos/specs, proof of purchase.
Shipping/transport damage to be reported immediately (supplier responsibility if shipped FOB/CIF etc).
Exclusions: misuse, improper handling, exceeding rated pressures/temps, corrosion from unapproved fluids, unauthorized modifications.
