Product catalog summary
Compressor Specifications
This section outlines the specifications of semi-hermetic screw compressors used in industrial and commercial refrigeration. The compressors are divided into series (SW1, SW2) and motor sizes (H for full size, L for small size), with nominal motor power ranging from 3000 to 25000 Hp. Displacement and weight vary based on these categories.
Key Features
Recent advancements focus on efficiency, noiselessness, compactness, and ease of installation and maintenance. RefComp has developed semi-hermetic screw compressors with external oil separators optimized for refrigeration applications.
Performance Data
Performance metrics include nominal motor power, displacement at 50/60 Hz, weight, and dimensions of discharge and suction lines. Starting and running currents are specified for different models, with capacity control options at 100%, 75%, and 50%.
Versatility and Efficiency
The compressors are available in two versions: SW2L for low evaporating temperatures and SW1H/SW2H for medium/high temperatures. Efficiency can be improved with an ECOnomizer circuit, particularly for medium and high compression ratios.
Additional Components
RefComp provides additional components such as oil separators, oil coolers, and economizers to enhance compressor performance.
Operational Limits
Operational limits are defined for full load at 50 Hz, with a maximum discharge temperature of 110°C and a suction gas superheat of 10K.
Refrigerant Performance
Performance data for refrigerants R404A/R507 and R22 are included, detailing cooling capacity, input power, and coefficient of performance (COP) with and without the ECOnomizer.
Conclusion
The document provides comprehensive technical specifications and performance data for RefComp's semi-hermetic screw compressors, emphasizing their adaptability, efficiency, and suitability for various refrigeration applications.
