Semi-hermetic Compact Screws - CSW Series SP-172-3
Semi-hermetic Compact Screws - CSW Series SP-172-3
The CSW series of semi-hermetic compact screw compressors are optimized for R134a liquid chillers, suitable for water-cooled, process cooling, and air-cooled systems in moderate climates. They offer improved efficiency for full and part load operations, with ESEER/IPLV values exceeding international standards.
Application Limits
These compressors operate efficiently within specific temperature and pressure ranges, suitable for various cooling applications.
Performance Data
Performance data comply with the European Standard EN 12900 for 50 Hz operation. The BITZER Software is recommended for precise compressor selection and performance data generation.
Technical Data
Features include a high-efficiency profile, advanced geometry, and a double-walled rotor housing for stability and sound attenuation.
Dimensional Drawings
Detailed drawings are provided for installation and integration into systems.
Special Highlights
Energy-efficient, compact, and flexible compressors with dual capacity control options, robust bearings, specially adapted motors, and intelligent electronics.
Accessories and Options
Optional accessories include shut-off valves, economiser ports, oil level switches, and anti-vibration mountings.
Detailed specifications and performance data focus on operation at 50 Hz according to EN 12900. Cooling capacity and COP are lower compared to data with subcooling.
Compressor Selection and Software
The BITZER Software allows for individual data input and provides output data including performance parameters and technical data.
Application Limits and Thermal Constraints
Application limits and thermal constraints are outlined, with performance data for R22 and R407C available upon request.
Performance Data and Operating Conditions
Data is provided for various compressor types, detailing cooling capacity and power consumption at different temperatures. Polyol-ester oil BSE170 is required for R134a operation.
Economiser Operation
Includes performance data for economiser operation involving liquid subcooling.
Specifications for compressor models include type, refrigerant type, displacement volume, weight, capacity control, motor connection, and power consumption.
Procedures and Recommendations
Outlines procedures for selecting contactors, cables, and fuses, emphasizing the use of oil heaters during long standstill periods.
Standards and Norms
Guidelines for selecting motor contactors according to operational category AC3.
Accessories and Oil Charge
Details on oil heaters and capacity control, specifying oil types for different refrigerants.
Dimensional Drawings
Includes drawings for various models, available in DXF and STP formats.
Additional Information
Mentions optional components like discharge and suction shut-off valves, and provides weight details for these components.
