Product Details

KSCY Mobile Diesel Screw Air Compressor Product Overview The KSCY Mobile Diesel Screw Air Compressor is a high-performance, portable industrial air compression solution designed for heavy-duty applications in remote and challenging environments. Powered by a robust diesel engine and utilizing advanced screw compression technology, this mobile unit delivers reliable, continuous airflow for demanding tasks such as mining, construction, oil and gas exploration, and infrastructure development. Its rugged construction and integrated mobility ensure seamless operation on any job site. Technical Features Efficient Screw Compression: Precision-engineered screw elements provide a high compression ratio with minimal energy loss, ensuring consistent air output at pressures up to 20 bar (290 psi) and flow rates ranging from 10 to 30 m³/min, depending on the model. Durable Diesel Engine: Equipped with a fuel-efficient, Tier 3/Stage V compliant diesel engine (e.g., Cummins or Deutz) that delivers maximum power while meeting stringent emission standards. Advanced Control System: An intelligent microprocessor controller monitors key parameters like temperature, pressure, and engine speed, allowing for automatic load/unload and safe shutdown in case of faults. Robust Mobility: Built on a heavy-duty chassis with pneumatic tires, towing hitch, and adjustable stabilizers, the KSCY can be easily transported and positioned on uneven terrain. Integrated Filtration: Multi-stage air filtration system (including oil separator and air/oil cooler) ensures clean, dry compressed air for sensitive tools and equipment. Noise Reduction: Sound-attenuated canopy reduces operational noise to below 75 dB(A), making it suitable for urban or noise-sensitive work sites. Application Scenarios The KSCY Mobile Diesel Screw Air Compressor is ideal for: Construction & Infrastructure: Powering pneumatic tools like jackhammers, drills, and concrete breakers on highways, bridges, and building sites. Mining & Quarrying: Providing compressed air for drilling, blasting, and material handling in open-pit and underground mines. Oil & Gas Exploration: Supplying air for wellhead operations, pipeline testing, and remote site equipment. Disaster Response & Emergency Services: Quick deployment for rescue operations, temporary power generation, or air supply in remote locations. Agriculture & Irrigation: Operating pneumatic irrigation systems and grain handling equipment in rural areas. Key Advantages Portability: Compact design and integrated wheels allow for rapid relocation without heavy lifting equipment. Reliability: Heavy-duty components and robust engineering ensure long service life even in extreme temperatures (-20°C to +50°C) and dusty environments. Cost-Effective Operation: Fuel-efficient diesel engine and low maintenance screw compression reduce total cost of ownership. User-Friendly: Intuitive control panel, easy access to service points, and optional remote monitoring via IoT enable hassle-free operation. Versatility: Compatible with a wide range of pneumatic tools and systems, with optional customization for specific pressure or flow requirements. Compliance: Meets international safety and environmental standards, including CE, ASME, and ISO 9001 certifications.
