Screw Air End Italian TMC Air Compressor Air End SCA8DA. This original TMC air end comes with a long life warranty, ensuring stable running and providing enough flow rate. Made with cast iron, it is a reliable and customizable component for your screw air compressor.
Technical Parameters
| Model | Power（kW） | Pressure(bar) | Diemension(mm) | Weight(kg) |
| SCA8DA | 5.5~11 | 3~15 | 217*184.5*164 | 18 |
1.High dynamic load adaptive control
A.Variable Speed Synchronous Reluctance Motor Drive:
The SCA8DA integrates a high-efficiency synchronous reluctance motor, which, combined with its dual-axis control core, can precisely control the meshing clearance and synchronization accuracy of the male and female rotors in real time. Even during rapid load changes (such as 0-100% load variation), it maintains extremely high volumetric efficiency (typical value > 95%).
B.Active Torsional Vibration Suppression Algorithm:
Addressing the inherent torsional vibration characteristics of the screw compressor, its embedded active damping system monitors and counteracts torque pulsations in the drive train in real time, reducing vibration by more than 40% and significantly extending bearing and gear life.
2.Thermodynamic-Mechanical Integrated Management
A.Integrated Thermal Flow Field Control: The SCA8DA's symmetrical heat dissipation architecture directly manages the thermal load during the compression process. By precisely controlling the oil injection temperature, flow rate, and rotor cavity temperature difference (maintainable within ±1.5°C), it optimizes the compression ratio and elevates isentropic efficiency to an industry-leading level.
B.Real-time Leakage Gap Compensation: Using high-precision position sensors, the system dynamically compensates for leakage gaps caused by thermal expansion by fine-tuning the rotor axial position in both hot and cold states, ensuring minimal internal leakage under all operating conditions.
3.Intelligent Energy Efficiency and Health Management
A.Model-Based Predictive Airflow Regulation: The compressor does not rely on simple PID control, but instead uses a real-time digital twin model to dynamically optimize the coordinated actions of the rotational speed, unloading valve, and intake valve based on air demand predictions and pipeline pressure, achieving "precise on-demand air supply."
B.Full Lifecycle Condition Monitoring: Built-in sensors continuously monitor parameters such as rotor geometric tolerances, bearing vibration spectrum, and motor magnetic field uniformity. Through the OPC UA interface, it provides early fault warnings (e.g., rotor coating wear, bearing preload reduction), transforming planned maintenance into predictive maintenance.
1.Ultimate Energy Efficiency, Lowering Total Cost of Ownership (TCO)
Compared to traditional variable-frequency screw compressors, the SCA8DA achieves an additional 8-12% energy savings under typical operating conditions. Its efficiency curve is flat, maintaining optimal specific power across a 40%-100% load range.
Predictive maintenance reduces unexpected downtime by 90% and extends major overhaul intervals by 20-30%.
2.Exceptional Reliability and Environmental Adaptability
Active vibration control and thermal management ensure minimal performance degradation even in harsh conditions such as high temperatures (up to 50°C ambient temperature) and high dust environments.
Material and coating technologies (SCA8 special alloy and wear-resistant coating) provide superior corrosion and wear resistance, making it particularly suitable for demanding environments such as chemical plants and offshore platforms.
3.Quiet and Compact Design
Excellent vibration control minimizes structural noise sources, and combined with optimized airflow design for aerodynamic noise control, the overall sound pressure level is 3-5 dB(A) lower than comparable products.
High power density design reduces the compressor size by approximately 15% at the same displacement and pressure, facilitating equipment integration and installation.
High-end manufacturing: Automotive painting and precision instrument assembly lines require absolutely oil-free compressed air and extremely stable pressure (fluctuation < 0.1 bar).
Process industries (chemical/pharmaceutical): process air, material handling, instrument air supply. The environment is highly corrosive, requiring 24/7 continuous operation and extremely high reliability.
New energy and semiconductors: Lithium-ion battery factory drying rooms, semiconductor cleanrooms. These facilities have strict requirements regarding air quality (particulate matter, dew point), vibration, and noise.
Energy-intensive sectors (mining/textiles): High energy consumption and significant load fluctuations. Extremely sensitive to electricity costs, and equipment often operates outside of its design parameters.
