Product catalog summary
Compressor Specifications
Semi-hermetic refrigerant compressors are optimized for R134a and other refrigerants such as R22, R407C, R404A, and R507. They are divided into XS and S series, with motor powers ranging from 40 to 300 Hp.
Electrical Accessories
Available in 220V AC, 110V AC, and 24V AC, with UL-approved options for 220V and 110V.
Capacity Control
Hydraulic slide valves provide capacity control in step or stepless modes, with 2, 3, or 4 steps, and an infinity option for some models.
Built-in Volumetric Ratio (Vi)
Vi values range from 2.2 to 4.4, with fixed and adjustable options to suit different applications.
Design and Efficiency
Designed for energy efficiency, quiet operation, compactness, and ease of installation and maintenance, featuring high-efficiency oil separators and optimized screw profiles.
Technical Data
Includes specifications on currents, displacement, weight, oil charge, and line dimensions for XS and S models.
Protection Devices
Standard protection includes INT 69 VS, with optional RefComp RCX available.
Applications
Suitable for air conditioning and refrigeration, with models for water and air condensing units and heat pumps.
Specifications
Details for 134-S and SRC-S series, with standard volumetric ratios of Vi=2.6 for SRC-S and Vi=3.2 for 134-S. Features include part-winding or Y/∆ motor, integrated valves, oil separator, and electronic protection device.
Procedures
Capacity control varies by model, with SRC-XS and 134-XS-040 offering three steps, and 134-XS-050 and 134-XS-060 offering two steps. The 134-S and SRC-S models offer four steps or stepless control.
Standards
Electrical accessories are designed for 230V-1-50/60 Hz, with special voltages available on request. The RefComp RCX module is compatible with 230/115V-1-50/60 Hz.
Recommendations
Additional accessories like special motors and oil flow switches can be requested. Specify desired capacity control during ordering.
Key Data
Compressors can be customized with different volumetric ratios and accessories, with detailed configuration options provided.
