CO2 Subcritical Semihermetic Compressors

Product catalog summary

Introduction
The CDS range of CO2 compressors is engineered for sub-critical applications, emphasizing enhanced pressure containment during system standstills. This design innovation mitigates rapid pressure increases when systems are off, preventing safety valve blow-offs and refrigerant loss. The compressors safely contain pressure up to 36 bar, suitable for cascade and booster installations.

Technical Specifications
The compressors have a maximum operating pressure of 55 bar and a safety pressure of 36 bar. They include high and low-pressure safety valves, suction and discharge service valves, and are compatible with frequency control. A special lubricant for CO2 applications is used, and the electric box is IP65-rated.

Application Limits
Operating limits for each model can be determined using the Dorin selection software. The application envelopes are valid for superheat values below 10K.

Performance Data
The CDS range features increased Coefficient of Performance (COP) due to optimized fluid dynamics and high-efficiency 4-pole motors, designed to minimize vibrations and gas pulsations.

Accessories
Standard accessories include high and low-pressure safety valves, suction and discharge service valves, and an IP65-rated electric box.

Overall Dimensions
Models are available with displacements from 1.9 m3/h to 48.8 m3/h at 50 Hz, catering to various application needs.

Specifications and Standards
The performance data for refrigeration systems using R744 (CO2) is based on the European Standard EN12900. For operations at 60 Hz, performance data should be multiplied by 1.18. Mixing ester oils with different oils is discouraged.

Components and Accessories
Components include motor protection modules, optical oil level sensors, and pressure relief valves for LP and HP. Standard and optional accessories are distinguished.

Performance Data
Detailed performance data is provided for different models, including refrigerating capacity and power input across various evaporating temperatures from -50°C to -20°C.

Overall Dimensions
Dimensions for different models are categorized under series CDS 11, CDS 35, CDS 41, with measurements in millimeters for length, height, and width.

Installation and Connection Details
Details include oil sight, oil charge plug, LP and HP taps, oil drain plug, crankcase heater, oil return plug, and safety valves, essential for installation and maintenance.
