Introduction
The document introduces the EK Series of hermetic compressors by Embraco, designed for use with CO2 (R 744) refrigerant. This series aims to provide an HFC-free refrigeration solution, promoting environmental sustainability.

Product Specifications
The EK Series compressors are designed for light commercial refrigeration, offering a new platform concept with single-stage operation in both Low Back Pressure (LBP) and Medium/High Back Pressure (M/HBP) segments. Key features include low sound levels, efficiency-driven design, broad capacity range, and suitability for variable capacity control (VCC) in premium applications.

Nomenclature
The compressor model nomenclature includes codes for refrigerant type, cooling capacity, application code, and efficiency level. For example, "EK S 6 210 CD" indicates a CO2 refrigerant with a cooling capacity of approximately 1000 kcal/h at 50Hz.

Technical Data
Test conditions for the compressors are specified, including evaporating temperature, discharge pressure, and return gas temperature. The document lists various models with their respective voltage, frequency, displacement, and estimated release dates.

CO2 Technology
Embraco emphasizes the use of CO2 as a natural refrigerant with the lowest Global Warming Potential (GWP). The technology is environmentally friendly and requires minimal changes to existing system designs. Applications include refrigeration, heat pumps, and dryers.
