Frascold open type screw compressors

Product catalog summary
Overview: The Frascold ATS open type screw compressors are engineered for reliability, flexibility, and efficiency in various applications such as refrigeration, air conditioning, and heat pumps. The range includes 16 models compatible with refrigerants like ammonia, hydrocarbons, and low GWP options, suitable for marine/industrial refrigeration, process cooling, heat pumps, air conditioning, and ATEX zones.
Specifications: Two main configurations are available: ATSH for low compression ratios and medium evaporating temperatures, and ATSL for high compression ratios and low evaporating temperatures. These compressors feature high precision bearings, innovative bearing configurations, and asymmetrical screw profiles for optimized performance.
Performance: The compressors deliver high cooling capacity with or without an economizer, low noise levels, and no vibrations. They are designed for easy installation and accessibility, featuring a compact design and direct motor coupling.
Maintenance and Longevity: Designed for long operational life, these compressors use special bearings to reduce noise and increase load resistance, requiring minimal maintenance due to their safe operational mechanics.
Technical Data: Detailed performance data is provided for various models, including cooling capacity and power consumption at different evaporating and condensing temperatures, with references to specific conditions like suction superheat and liquid subcooling.
Optional Accessories: A range of optional accessories is available, such as coupling joints, discharge and suction valves, oil separators, and oil filters, enhancing the compressors' functionality and adaptability for specific applications.
Model Designation: The model designation provides information on the compressor family series, standard supply, and optional accessories, offering a clear understanding of the product offerings.
Performance Data: Tables show cooling capacity (Qo) and power consumption (Pe) across various temperatures for different compressor models, segmented by refrigerant type and frequency (50Hz), providing insights into efficiency and operational limits.
Working Limits: The document specifies working limits for ATSH1 and ATSL1 models, including evaporating and condensing temperatures, superheat, and subcooling conditions, emphasizing the need for additional cooling in certain scenarios and suggesting the use of selection software for precise requirements.
Dimensional Drawings: Detailed drawings for each compressor model indicate connections for oil return valves, discharge temperature sensors, capacity control valves, and other critical components, with dimensions provided for installation and integration purposes.
Company Information: Frascold SpA is highlighted as a company with over 75 years of experience in manufacturing compressors for refrigeration and air conditioning, focusing on energy-saving solutions and adhering to quality and construction directives.
