Dual-mode screw compressors are highly efficient and energy-efficient compressed air equipment. Their core advantage lies in their ability to intelligently switch between two different operating modes (such as high/low pressure and varying load conditions) based on actual needs, achieving precise air supply and significant energy savings. Utilizing an advanced screw airend and intelligent control system, they automatically optimize operating parameters under varying operating conditions, ensuring stable and efficient output. Advantages include: outstanding energy savings, with stepless regulation and dual-mode switching to avoid wasted idle time; high reliability, with a robust structural design ensuring long-term continuous operation; and strong adaptability, making them particularly suitable for applications with fluctuating gas loads, such as manufacturing, chemical, and mining industries, significantly reducing operating costs.
Features of Double-condition screw compressor machine
① Equipped with Cummins and Yuchai high-quality brand diesel engines;
② Heavy-duty engine head design, excellent performance, and upgraded energy efficiency;
③ Integrated normally open and normally closed two-in-one function to solve the low-temperature starting difficulties and piston seal failure problems of conventional intake valves;
④ Equipped with Fleetguard air filtration system, double filter elements ensure that the compressor inhales cleaner air;
⑤ High temperature resistant design, suitable for severe high temperature weather;
⑥ Fully automatic control and protection system.

FAQ
Q: What is the maximum drilling/coring depth?
A: Currently 800m, but can be customized for higher requirements.
Q: What power source does the drilling rig use (diesel, electric, or hybrid)? What is the energy consumption?
A: Primarily diesel, but other power sources are also available, mainly depending on customer needs.
Q: What brands are used for core components (such as engines and hydraulic systems)? Can they be customized?
A: All parts use internationally renowned brands, such as Yuchai and Cummins engines. These parts can be customized according to customer needs.
Q: Are there any special drill bits recommended for different rock formations?
A: Yes, we will understand your working environment before recommending drill bits and then provide the optimal solution.
Q: What is the deposit percentage?
A:30% T/T as deposit, full balance before delivery
Q: Can you assist with customs clearance documents (such as certificate of origin, commercial invoice, packing list)?
A: Yes
Q: Do you provide operation training, installation instructions, or maintenance manuals (in English)?
A: Yes
Q: Can you customize solutions according to our specific project requirements (such as special bore diameters or depths)?
A: Yes.
Q: What is the operating pressure (PSI/Bar) and discharge volume (CFM) range of the air compressor?
