The TMC SCA20DR is a robust, high-capacity rotary screw compressor air-end engineered in Italy for demanding industrial applications. The model designation "SCA20DR" indicates a specific series and size within TMC's portfolio, typically representing a larger displacement unit designed for high-volume air output. As the core mechanical heart of a screw compressor, it is synonymous with continuous-duty performance and operational economy.
Technical Parameters
| Model | Power（kW） | Pressure(bar) | Diemension(mm) | Weight(kg) |
| SCA20DR | 110 | 3~15 | 617*459*350 | 263 |
High-Displacement Design:
The "SCA20" series is engineered for substantial air delivery. The SCA20DR is typically capable of providing flow rates in the range of 30 to 45 m³/min (approximately 1,050 to 1,600 CFM) at standard industrial pressures (7-13 bar).
It incorporates TMC's proprietary asymmetric rotor profile, scaled and optimized for this larger displacement to maximize volumetric efficiency and compression smoothness.
Heavy-Duty Construction for Continuous Operation:
The rotors are precision-machined from high-grade, high-tensile forged alloy steel to withstand the significant mechanical stresses of continuous high-output operation.
It features a reinforced housing and utilizes large-diameter, high-precision angular contact bearings designed to manage substantial axial and radial loads, ensuring permanent rotor alignment and stability over decades of service.
Advanced Lubrication & Cooling Architecture:
The design incorporates optimized, large-section internal oil injection channels and passages to ensure effective cooling, lubrication, and sealing of the large compression chamber, which is critical for managing heat and maintaining efficiency at high outputs.
Class-Leading Energy Efficiency at High Flow:
The optimized rotor profile and precision engineering result in exceptionally low specific energy consumption (kW/m³/min) for its class. This translates into major operational cost savings, which are most significant in large-scale, 24/7 applications.
Unmatched Reliability and Extended Lifespan:
Built for 100,000+ hours of continuous operation before a potential major overhaul. The over-engineered bearing system and premium materials provide exceptional durability, minimizing unplanned downtime in critical operations.
Operational Stability and Low Maintenance:
Delivers extremely stable air pressure and flow with minimal pulsation, which is essential for large, connected systems and sensitive processes. Its robust design leads to long service intervals and predictable maintenance, reducing the total cost of ownership (TCO).
Robust Performance in Challenging Environments:
Engineered to maintain high efficiency and reliability even under high ambient temperatures and variable load conditions common in large industrial plants.
Heavy Manufacturing & Automotive Plants: Powering extensive networks of pneumatic tools, automation cells, robotic welding lines, paint systems (with treatment), and large press lines.
Metals & Foundries: Supplying air for furnace controls, large-scale sandblasting, material handling, and casting equipment.
Chemical & Petrochemical Processing: Providing large volumes of reliable instrument and plant air for valve actuation, process agitation, pneumatic conveying, and safety systems in refineries and chemical plants.
Large-Scale Food & Beverage Production: Serving as the central air supply for major bottling lines, canning operations, packaging halls, and processing equipment (using oil-free variants or with high-grade filtration).
Power Generation & Utilities: Supplying critical instrument air for control systems in gas turbine or coal-fired power stations, as well as for general service air in large maintenance facilities.
Mining & Minerals Processing: Powering pneumatic tools, controls, and separation equipment in demanding environments.
