Product catalog summary
Overview: The document provides comprehensive technical specifications and features of the CSH-Series semi-hermetic compact screw compressors, specifically models 65, 75, 85, and 95. These compressors are designed for use with refrigerants R134a, R407C, and R22, emphasizing their energy efficiency, compact design, and application flexibility.
Special Highlights:
  • Energy Efficiency: The compressors feature a high-efficiency profile with infinite or closely stepped capacity control and optimal economiser operation.
  • Universal Application: They are compatible with multiple refrigerants and available with or without an economiser.
  • Compact Design: The compressors have the shortest fitting length in their class, with integrated shut-off valves and connections.
  • Flexibility: Dual capacity control allows switching between 4-stage and infinite capacity control without compressor modification.
  • Optimised for R134a: Enhanced motor power and extended capacity and application range for economiser use.
Technical Features:
  • High-Efficiency Profile: Advanced geometry and high stiffness with a patented manufacturing process for precision.
  • Double-Walled Rotor Housing: Provides stability and sound attenuation even at high pressures.
  • Long-Life Bearings: Robust axial tandem bearings with pressure unloading.
  • Large Volume Motor: High efficiency with integrated PTC sensors and optional star-delta design.
  • Dual Capacity Control: Offers infinite or 4-step slider control with Vi compensation.
Performance Data: Based on European Standard EN 12900 and 50 Hz operation, the document details performance metrics for different refrigerants, emphasizing dew point conditions and the impact of zeotropic blends like R407C on performance parameters.
Additional Features:
  • Economiser Operation: Unique sliding suction position for efficient operation at full and part load conditions.
  • Intelligent Electronics: Includes thermal motor temperature monitoring and phase sequence monitoring.
  • Optimised Oil Management: Features a three-stage oil separator and fine filter for enhanced efficiency.
  • Comprehensive Equipment: Includes capacity control, start unloading, and various valves and sensors for optimal operation.
Conclusion: The CSH-Series compressors set a global standard for innovation and efficiency in refrigeration technology, offering versatile and efficient solutions for various applications.
Specifications and Standards: The document discusses the adoption of European Standard EN 12900 for screw compressors in the CSH series, focusing on performance data and conditions such as liquid subcooling and economiser operation. It highlights that standard conditions do not consider liquid subcooling, resulting in lower rated cooling capacity and efficiency (COP) compared to data with 5 or 8.3 K subcooling.
Economiser Operation: Economiser operation inherently includes liquid subcooling, with the liquid temperature defined as 5 K above the saturated temperature at the economiser inlet, according to EN 12900.
Individual Operating Points: The BITZER Software is available for detailed compressor selection, allowing for individual data input. It provides output data including performance parameters, application limits, technical data, and dimensional drawings. Specific data sheets can be generated for further use.
ASERCOM Certification: The document details the ASERCOM certification process for compressor performance data, ensuring high standards through expert plausibility checks and regular tests at independent institutes. Only compressors meeting strict requirements carry the "ASERCOM certified product" label.
Application Limits: Thermal limits for capacity control and additional cooling depend on the compressor type. The maximum condensing temperature may be restricted for certain types, and extended application limits are possible depending on system layout, requiring coordination with BITZER.
Performance Data: Performance data is based on 10 K suction superheat without liquid subcooling. The document provides detailed tables of cooling capacity and power consumption for various compressor types and operating conditions.
Additional Cooling Requirements: For part-load operation, application limits can be lifted with liquid injection by 5 K in condensing temperature, up to full-load limits. External oil cooling is required for certain operations.
Overview: This document also provides technical details about the BITZER Software CD-ROM and connection positions for a specific product. It includes information on where to download the software and details about various connection points on the equipment.
Software Access: The BITZER Software can be downloaded from the following websites: www.bitzer.it, www.bitzer-corp.com, and affiliate websites of BITZER. Upon request, 3D models in VRML, STEP, or IGES formats are available.
Connection Positions: The document lists various connection points on the equipment, each with a specific function, including high and low pressure connections, oil sight glass, oil service valve, oil drain plug, oil charge connection, oil level switch, oil heater, oil pressure connection, external oil cooler connection, oil temperature sensor, economiser or liquid injection connection, thread for pipe support, and grounding screw for housing.

Performance data are based on the European Standard EN 12900 and 50 Hz operation. I dati di resa si basano sulla norma Europea EN 12900 e sul funzionamento a 50 Hz. Die Verdampfungs- und Verflüssigungstemperaturen beziehen sich darin auf ''Taupunktwerte'' (Sattdampf-Bedingungen). Bei zeotropen Gemischen, wie R407C, verändern sich dadurch die Bezugsparameter (Drucklagen, Flüssigkeitstemperaturen) gegenüber bisher üblicherweise auf ''Mitteltemperaturen'' bezogene Daten. Als...
