Core advantages
Based on the following three advantages:
🔧 Oil-free clean technology
Precision vane mechanism (Dry Techâ„¢).
100% oil-free exhaust without oil contamination (Certified ISO 8573-1 Class 0).
150-180°C compression chamber for pathogen inactivation (Medical-grade safety).
🔇Extended lifespan & Silent operation
Self-lubricating carbon vanes:
≥8,000-hour service interval (2× conventional oil pumps).
Sound-insulated enclosure: ≤60 dB(A) (ISO 2151 compliant).
🚀 Intelligent control system
Touchscreen HMI: Multi-stage power adaptation, fault pre-alert, energy monitoring.
4G remote O&M & Modbus TCP (Industry 4.0 ready).
Applications
- Medical vacuum: Pathogen interception filter and thermal sterilization(EN ISO 13485:2016).
- Food packaging: Full stainless-steel flow path and zero hydrocarbon emission.
- Semiconductor handling: ESD-safe design and pulse-jet dust cleaning.
- Lab drying: PID vacuum control (±1kPa accuracy, DIN 28401 Class III).
Multi-unit system architecture
Redundant parallel operation
- Modular scalability: Up to 10 units in parallel (40% footprint reduction). Front/rear maintenance accessibility.
- Eliminating single-point failure: Any subunit configurable as master controller (Automatic master unit failover during subsystem faults).
- Dynamic load optimization: Real-time vacuum demand tracking via Modbus network. Achieving optimal load tracking and maintain optimal vacuum with minimal power consumption.
Operational principle
Three-phase oil-free compression:
Intake: Eccentric rotor expands chamber volume (60kPa optimal range).
Isolation & compression: Vanes isolate gas, adiabatic compression initiates.
High-temp exhaust: Gas discharged at 150°C+ via check valve (99.2% inactivation per ISO 18593).
