LGZJ/KSZJ High Pressure Mining Air Compressors for Water Well & Geothermal Drilling

LGZJ/LGCC/KSZJ Series High Pressure Diesel Screw Air Compressor – The Ultimate Power Source for Deep Drilling Operations

The LGZJ, LGCC, and KSZJ series high pressure diesel screw air compressors represent the pinnacle of Kaishan's compression technology, specifically engineered for the most demanding drilling applications worldwide. Whether powering water well drilling rigs, geothermal well projects, or oil and gas exploration, these compressors deliver the high-pressure air required for deep formations and challenging conditions.

Engineered for Drilling Excellence

With pressure ratings up to 3.5MPa (35 bar) and flow rates from 18 to 43 m³/min, these compressors provide the power needed for:

• Deep water well drilling – maintaining high pressure for DTH hammers at depths exceeding 500m

• Geothermal well projects – reliable continuous operation in high-temperature environments

• Oil & gas exploration – consistent air supply for air drilling and aerated mud systems

SKY Patented Screw Air End – Designed for 40Bar

Each compressor features the globally patented SKY rotor profile, engineered for 40bar maximum pressure capability. The innovative two-stage compression design incorporates flexible lift valves that optimize efficiency across the entire operating range. Heavy-duty construction with SKF bearings ensures the highest reliability and longest service life during continuous drilling operations.

Dual Mode Operation for Maximum Versatility

Understanding that drilling conditions change, our compressors feature innovative dual-mode design. Operators can quickly switch between operating modes to match specific well requirements. For example, models can deliver 33m³/min @ 25bar for large-diameter holes or switch to 26m³/min @ 35bar for deep, high-pressure drilling – all from a single machine.

Heavy Duty Diesel Power for Remote Locations

Powered by world-class Yuchai or Cummins heavy-duty diesel engines meeting global emission standards, these compressors deliver optimal combustion throughout the operating range. This provides:

• Higher reliability for remote drilling sites

• Stronger power output for deep formations

• Superior fuel economy for extended operations

• Easy maintenance with globally available parts

Advanced Computer Control with Remote Monitoring

The full-color display shows real-time operating parameters critical for drilling operations: air pressure, engine speed, oil pressure, exhaust temperature, coolant temperature, and fuel level. Self-diagnostic functions with alarm and automatic shutdown ensure safe unattended operation. Optional remote network monitoring allows drilling supervisors to monitor compressor status from their office or even from home.

Efficient Cooling for Any Climate – From Desert to Arctic

Developed by Kaishan's North American R&D Center, the advanced cooling system features independent oil, water, and air coolers with large diameter fans. This ensures optimal operating temperatures in the most extreme environments where drilling takes place – from Middle Eastern deserts to Siberian winter conditions. Rated for -30°C to +45°C ambient temperatures.

Triple Filtration for Harsh Drilling Environments

• Air Filtration System: Patented centrifugal pre-filter removes over 90% of dust and contaminants, extending filter life by 5x – critical for desert and dusty drilling sites. Cyclonic main filter captures remaining particles, with safety element allowing maintenance without stopping operations.

• Oil Separation System: Maintains compressed air oil content below 3ppm, ensuring clean air delivery to sensitive DTH hammers and drilling tools, extending their service life.

• 10 Micron Oil Filter: Ensures minimal wear on moving components with multiple fuel filtration protecting the injection system.

Optional Cold Start System for Arctic Operations

For drilling operations in cold climates, high-altitude regions, or winter drilling campaigns, the optional cold start system circulates heated coolant and fuel to ensure reliable diesel engine starting even in extreme cold down to -40°C.

Optional Aftercooler and Water Separator

For applications requiring dry air, the optional aftercooler and water separator ensure discharge air temperature remains within 15°C of ambient, making these compressors ideal for use with boosters or for operations where low-temperature air is required.
