Twin-Screw Airend
At the core is a revolutionary twin-screw main unit featuring diamond-coated tungsten carbide rotors, delivering 5× wear resistance and 99% volumetric efficiency under sustained ultra-high pressure. The 9:13 hyper-asymmetric tooth profile incorporates active thermal expansion compensation, maintaining optimal rotor clearance across a −40 °C to 120 °C temperature range for unmatched stability.
High-Efficiency Powertrain
The drive system integrates an axial-flux permanent magnet motor with a flux-concentrated Halbach array (IE5+++ efficiency), achieving 70% higher power density than conventional designs. It is paired with a zero-backlash planetary gearbox (99.5% transmission efficiency) to minimize energy loss through the drivetrain.
Intelligent VFD & Energy Savings
Equipped with a neural-network-driven variable frequency drive (VFD), the compressor adapts in real time to fluctuating loads, maintaining ±0.002 MPa pressure precision while achieving a class-leading 7.6 kW/(m³/min) efficiency ratio per ISO 1217:2024. This reduces energy consumption by up to 65% versus legacy high-pressure models.
Eight-Stage Oil Removal System
Air purity is ensured through an eight-stage oil removal system combining:
Cyclonic separation
Gradient-pore sintered diamond filters
Carbon nanotube adsorption
Final perovskite membrane layer
The result is residual oil content ≤3 ppm, exceeding ISO 8573-1:2010 Class 1.1.0-suitable for ultra-clean aerospace and nuclear-grade applications.
Thermal Management & Noise Reduction
A cryogenic hybrid cooling system integrates a microchannel liquid-cooled oil circuit with phase-change coolant and thermoelectric Peltier modules, enabling continuous operation in 85 °C ambient temperatures with <1% efficiency derate.
Noise is controlled through active vibration cancellation (AVC) technology and aerodynamic acoustic vanes, limiting operational noise to 73 ± 2 dB(A)-25% quieter than equivalent 55 kW ultra-high-pressure compressors.
Intelligent Control Platform
The control system features a 27-inch sunlight-readable HMI with edge AI processing, monitoring 70+ parameters in real time, including rotor torsion stress, oil film thickness, and harmonic distortion.
Tri-mode connectivity (5G / Starlink / Industrial Ethernet) supports:
Global remote diagnostics
Predictive maintenance via digital twin technology
Over-the-air system recalibration
Maintenance & Construction
Self-sealing quick-change filter cartridges and a fully automated oil management system extend service intervals to 5,000 hours-50% longer than industry norms.
Housed in a forged titanium-alloy frame with seismic-grade anti-vibration mounts, the compressor excels in mission-critical scenarios including:
Deep-earth geothermal drilling
High-pressure hydrogen compression
Aerospace turbine testing
PET bottle blowing and high-pressure industrial processes
