Carlyle 06TSA186 75HP Screw Refrigeration Compressor for Commercial AC Unit

The 06TSA186 screw refrigeration compressor is engineered for high-demand air-cooled chillers, process cooling, and commercial refrigeration systems. Operating with eco-friendly R134a refrigerant alongside a wide range of alternative refrigerants including R22, R404A, R407C, R507, R448A, and R449A, it delivers exceptional thermodynamic performance across high, medium, and low-temperature applications.

Powered by a 75 HP motor delivering a maximum displacement of 186 CFM (312 m³/h at 60Hz) or 155 CFM (258 m³/h at 50Hz), this unit utilizes patented high-efficiency screw rotor geometry to minimize gas slippage clearances. An integrated economizer circuit with a 1-3/8 in. interface further maximizes subcooling capacity and operational efficiency.

To match fluctuating thermal loads across industrial operations, the unit features a dual solenoid valve capacity control system that enables smooth, stepless capacity regulation from 100% down to 15%. Integrated volume ratio (Vi) optimization under partial load conditions prevents over-compression and under-compression losses, drastically reducing total power consumption during off-peak duty cycles.

Designed for continuous heavy-duty service without requiring an external oil pump, the compressor relies on high-load SKF or NSK rolling bearings combined with a reinforced thrust bearing structure for long service life. Safety features and internal protective devices include:

• Internal Check Valve: Prevents reverse rotor rotation and protects rotor profiles from wear caused by pressure backflow during shutdown.
• Safety Relief Valve: Safeguards internal housing against abnormal pressure surges.
• External Oil Filter: Simplifies routine maintenance and service inspections without disassembling the housing.
• Motor Protection Module: Equipped with NTC thermistors, phase loss, reverse rotation, and discharge temperature monitoring.

Every 06TSA186 screw refrigeration compressor undergoes 100% factory run testing and a 33-point quality process inspection prior to shipment. The high-strength motor supports Star-Delta and Direct-On-Line (DOL) starting modes across multiple global commercial voltage standards (200V-460V at 50Hz/60Hz).

• Standard Accessories: Terminal Box, Oil System Assembly, Motor Protection Module, Capacity Regulation Device, Stop Valves.
• Optional Accessories: Oil Separator, Mounting Flanges, Economizer Assembly, Oil Cooler, High-Temperature Expansion Valve, Kriwan Protection Module, and Paragon Control Board.
