Product Overview
LNP180-70/GQ-HR 180K liquid nitrogen pump skid is integrated skid-mounted high-flow nitrogen stimulation equipment, specially matched with 40K/60K/80K/100K skid coiled tubing units for onshore oil & gas well service. Powered by genuine CAT C15 540HP industrial diesel engine, this unit adopts engine exhaust waste heat recovery vaporization system, eliminating extra combustion heating devices and greatly cutting operation fuel cost. The whole skid integrates USA CS&P cryogenic booster pump, triplex high-pressure LN2 plunger pump, DURST transfer box, LINDE full closed hydraulic system, stainless PLC control cabinet, 400L self-contained fuel tank and SPIR STAR high-pressure manifold. Max nitrogen output reaches 180,000 SCFH (5097Sm³/h) with adjustable flow from 21,000 SCFH, rated working pressure up to 10,000PSI (69MPa). Discharge nitrogen temperature stably maintained at 15℃~21℃. Full set equipment pre-assembled on heavy-duty steel skid with rainproof frame, suitable for -29℃ ~ +45℃, altitude ≤1000m oilfield environments, widely applied in nitrogen foam fracturing, well cleanout, displacement, snubbing and underbalanced drilling operations. Complies with ISO9001 oilfield equipment manufacturing standards.

7 Core Product Advantages
Genuine CAT C15 Heavy-Duty Power Unit
Original CAT C15 six-cylinder 540HP diesel engine with triple radiator (water/fuel/hydraulic oil integrated cooling), stable full-load operation under +45℃ high temperature. Matched DURST three-way split transfer box evenly distributes power to multiple hydraulic groups, providing sufficient power for long-hour large-flow nitrogen pumping construction. Global CAT parts supply network supports overseas after-sales maintenance.Zero Extra Fuel Waste Heat Vaporization System
Adopts engine exhaust heat recovery design, recycles flue gas heat to heat water-bath vaporizer, no auxiliary fuel burner required. Nitrogen outlet temperature locked 15~21℃ constant, avoids ultra-low temperature pipeline frost cracking risk, drastically reduces daily operation fuel consumption and customer service cost.Wide Adjustable Flow Range (21K~180K SCFH)
High-efficiency triplex plunger pump with stepless speed regulation from 60~1200RPM. Covers small-volume well testing (21K SCFH) and large-scale fracturing injection (180K SCFH). 90% pump volumetric efficiency lowers energy loss during continuous pumping.Imported Cryogenic & Hydraulic Core Components
USA CS&P low-temperature centrifugal booster pump stably feeds liquid nitrogen to high-pressure plunger pump; LINDE closed hydraulic system realizes stepless flow control; SPIR STAR ultra-high pressure stainless manifold with 20,000PSI safety margin, zero leakage under long-term 10,000PSI working pressure. All key international brands guarantee stable long-term running.Full PLC Intelligent Monitoring Control Cabinet
Stainless steel airtight control cabinet integrates full-function PLC system, real-time display & record data: engine RPM/oil temp, booster pump speed, nitrogen flow/temp/pressure, plunger pump outlet pressure (0~10,000PSI), hydraulic oil temperature. Auto overpressure/overheat/low-pressure alarm protection prevents equipment damage; supports data export for construction record tracking.Integral Self-Contained Skid Design
All power, pumping, vaporization, manifold and control modules pre-installed on one heavy steel skid with rain protection frame. Equipped 400L self-contained fuel tank, reserved integral lifting lugs for truck/container separate transportation. Hydraulic quick connectors shorten site rig-up time without complicated pipeline layout.All-Climate Harsh Environment Adaptation
Full skid sandblasting heavy anti-corrosion coating; hydraulic system equipped low-temperature heater for -29℃ northern oilfield startup. Adapt desert, mountain, coastal high-humidity onshore well sites, fully meets oilfield HSE safety operation standards.Main Application Scenarios
