CDS SERIES CO2 COMPRESSORS FOR SUB-CRITICAL APPLICATIONS

Product catalog summary
Introduction
The CDS range of CO2 compressors is engineered for sub-critical applications, emphasizing enhanced pressure containment during extended system standstills. This feature is vital as CO2 refrigeration systems can experience rapid pressure increases when inactive, risking safety valve blow-offs and refrigerant loss. The CDS compressors are designed to safely contain pressure up to 36 bar, making them suitable for cascade and booster installations.

Technical Data
The compressors have a maximum operating pressure of 55 bar and a safe pressure of 36 bar. They are equipped with high-efficiency 4-pole motors and optimized internal vane shapes to enhance the coefficient of performance (COP). The reliability of these compressors is proven with thousands of units in operation.

Application Limits
Users should consult the Dorin selection software to determine the specific operating limits for each model. The application envelopes are valid for superheat values below 10K.

Accessories and Features
The compressors include high and low-pressure safety relief valves, suction and discharge service valves, and are compatible with frequency control. They feature low vibrations and gas pulsation, special lubricants for CO2 applications, and an IP65-rated electric box.

Performance Data
The CDS range offers displacements from 1.9 m3/h to 48.82 m3/h at 50 Hz, with various models providing different power and current specifications to cover a wide range of applications.

Overall Dimensions
Detailed dimensions for each compressor model are provided to ensure proper fit and installation in different systems.

Conclusion
The CDS range of compressors provides a robust solution for sub-critical CO2 applications, combining innovative design with proven reliability and efficiency.

INTRODUZIONE / INTRODUCTION / INTRODUCTION / EINFOHRUNG CDS RANGE The new CDS compressor range for subcritical applications benefit a specific product engineering intended to increase pressure containment criteria, especially when the system is subjected to prolonged standstill. As a matter of fact, CO2 refrigeration systems are subject to quick pressure raise in case for any reason the installation is turned off for a prolonged amount of time; depending on the system configuration, this may lead to a safety valve blow-off with consequent refrigerant charge loss and potential serious damage to...
