A new series of semi-hermetic compact screws SP-174-2
A new series of semi-hermetic compact screws SP-174-2
The document introduces a new series of semi-hermetic compact screw compressors, specifically models CSH6581, CSH6591, CSH95101, and CSH95111. These compressors are widely used in air conditioning and heat pump applications.
Specifications
The series has been expanded with four additional compressors, offering 21 displacement steps ranging from 137 m3/h to 1120 m3/h for 50 Hz operation. The compressors are characterized by energy efficiency, flexibility, compact dimensions, and optimized oil management.
Energy Efficiency
- High-efficiency profile
- Infinite or closely stepped capacity control
- Optimum economiser operation
Flexibility
- Dual capacity control: switchable between 4-stage and infinite capacity control without retrofitting
- Suction and discharge gas connections rotatable in 90° increments
Oil Management
- Four-stage oil separator
- Fine filter with 10 µm mesh size
- Pressure relieved bearing chamber for minimal refrigerant concentration in oil
Performance Data
The document provides performance data for 50 Hz operation based on 10 K suction superheat without liquid subcooling. It includes cooling capacity and power consumption for various compressor types and operating conditions.
Technical Data
Technical specifications include motor version, displacement, weight, capacity control, motor connection, maximum operating current, power consumption, starting current, and oil charge. The compressors offer infinite or 4-step capacity control (100%, 75%, 50%, 25%).
Connection Positions
The document details connection positions for high and low pressure, oil sight glass, oil service valve, oil charge connection, oil level switch, oil heater, oil pressure connection, external oil cooler connections, oil temperature sensor, economiser or liquid injection connection, and grounding screw.
Conclusion
The new series of compressors offers enhanced performance and flexibility for various applications in the refrigeration and air conditioning sector.
