1. Water Well Drilling
The compressor is specifically designed for water well drilling projects ranging from agricultural irrigation wells to municipal water supply systems. It provides sufficient airflow and pressure for medium and deep well drilling operations.
2. DTH Drilling Operations
Ideal for crawler-mounted DTH drilling rigs used in mining, quarrying, foundation engineering, and blast-hole drilling. The high-pressure output ensures optimal hammer performance and faster penetration rates.
3. Quarry and Open-Pit Mining
Suitable for drilling blast holes in limestone, granite, basalt, marble, and aggregate quarries. The compressor supports efficient rock fragmentation and production blasting activities.
4. Geothermal and Exploration Drilling
The high-pressure compressed air system is capable of supporting geothermal drilling, geological exploration, and resource investigation projects in challenging geological formations.
5. Infrastructure and Foundation Engineering
Widely used for anchoring, micropiles, foundation reinforcement, slope stabilization, and other engineering drilling projects requiring reliable high-pressure air supply.
1. High-Pressure Performance for Deep Drilling Applications
With a powerful output of 21m³/min at 21 bar, the KYLC-21-21CY delivers the airflow and pressure required for deep water well drilling, DTH drilling, and large-diameter borehole applications. The high-pressure design significantly improves drilling speed and efficiency.
2. Advanced Two-Stage Compression Technology
The two-stage compression system provides higher efficiency, lower discharge temperatures, and improved fuel economy compared with conventional single-stage compressors. This results in greater reliability and lower operating costs during continuous drilling operations.
3. Multiple Engine Options for Global Markets
Customers can choose between Yuchai and Cummins diesel engines according to local service availability, emission requirements, and project preferences. Both options deliver excellent power output and dependable performance.
4. Designed for Extreme Working Conditions
Featuring Fleetguard filtration, heavy-duty cooling systems, and optional desert air filters, the compressor is engineered for operation in hot, dusty, and remote environments commonly found in Africa, South America, the Middle East, and Central Asia.
5. Factory Direct Supply with Customization Support
As a manufacturer-direct product, the KYLC-21-21CY offers competitive pricing, customized engine configurations, remote-control options, cold-start heating systems, and comprehensive OEM solutions for international distributors and contractors.
Q1: What drilling rigs can the KYLC-21-21CY support?
The compressor is compatible with a wide range of DTH drilling rigs, water well drilling rigs, anchor drilling rigs, and engineering drilling equipment requiring approximately 21 bar working pressure.
Q2: What depth of water well drilling is this compressor suitable for?
When paired with an appropriate water well drilling rig, the KYLC-21-21CY is commonly used for drilling depths ranging from 200 to 500 meters, depending on geological conditions and borehole diameter.
Q3: Which DTH hammer sizes can this compressor operate?
The 21m³/min airflow and 21 bar pressure are suitable for 4-inch, 5-inch, and many 6-inch DTH hammers used in mining and water well drilling applications.
Q4: Can I choose between Yuchai and Cummins engines?
Yes. Customers can select either Yuchai or Cummins engines based on project requirements, local service networks, and budget considerations.
Q5: What customization options are available?
We offer desert air filtration systems, diesel engine coolant heating systems, remote-control functions, customized branding, paint colors, and other OEM/ODM solutions.
