Carrier 06TSR223 High-Capacity Screw Type Refrigeration Compressor for Freezing

Engineered specifically for demanding low-temperature operations—such as quick-freezing tunnels, large blast freezers, and industrial cold storage distribution centers—the 06TSR223 screw type refrigeration compressor delivers massive displacement up to 483 CFM (809 m³/h at 60Hz) and 403 CFM (670 m³/h at 50Hz). Driven by a heavy-duty 90 HP motor, this semi-hermetic twin-screw unit utilizes patented rotor geometry designed to maintain high volumetric efficiency even under extreme compression ratios. Optimized for low-temperature refrigerants including R404A, R507, and R22, its integrated 1-3/8 in. economizer port significantly boosts subcooling capacity to deliver maximum cooling effect per kilowatt.

Rather than running at fixed steps, the 06TSR223 features a smooth 25% to 100% stepless capacity modulation system controlled via dual solenoid valves. This continuous responsiveness allows the compressor to adjust instantly to real-time thermal loading during batch loading or pull-down cycles. By optimizing the internal volume ratio (Vi) at partial loads, the unit prevents over-compression penalties, maintaining stable evaporating pressures while drastically cutting facility energy bills.

Built to minimize costly downtime in continuous process freezing operations, the 06TSR223 screw type refrigeration compressor eliminates complex external oil pumps by utilizing internal pressure differential lubrication. High-precision SKF/NSK rolling bearings and specialized axial thrust bearings easily absorb heavy mechanical loads. Key maintenance and safety highlights include:

• External Oil Filter: Mounted externally for quick inspection and tool-free replacement during routine service intervals.
• Built-In Reverse Rotation Protection: An integrated internal check valve stops backflow gas from reversing the rotors during shutoff.
• Comprehensive Thermal Protection: Winding-embedded NTC thermistors continuously monitor motor temperatures against thermal overload.

• Standard Included Components: Terminal Junction Box, Solenoid Capacity Control Valves, Motor Protection Module, Suction & Discharge Service Valves, Oil Line Assembly.
• Optional Add-On Modules: Oil Separator, Liquid/Gas Economizer Kit, External Oil Cooler, Counter Flanges, Kriwan Electronic Diagnostics Module, Paragon Controller.

With an impressive displacement of 809 m³/h at 60Hz, a single 06TSR223 provides the high volumetric capacity required for rapid heat extraction in deep-freeze applications. Consolidating capacity into a high-output unit simplifies rack piping, reduces electrical panel footprint, and streamlines overall maintenance schedules.

The compressor uses high-efficiency internal pressure differential channel design to circulate lubricant continuously to the bearings. Eliminating mechanical oil pumps removes a common point of mechanical failure, ensuring immediate oil supply to SKF/NSK bearing assemblies during system startup.

Yes, the 06TSR223 fully supports R22 as well as HFC replacements like R404A and R507. Its standard flange interface dimensions and wide voltage tolerance facilitate straightforward drop-in replacement during plant modernizations.

Thanks to its external spin-on design, maintenance technicians can inspect or replace the oil filter quickly without tearing down compressor housing covers or opening internal oil cavities. Routine replacements are recommended during annual system overhauls or whenever pressure differential sensors signal a filter drop.

Every compressor is thoroughly tested, vacuum-dried, nitrogen-charged, and sealed in heavy-duty export plywood crates with moisture-proof wrapping to guarantee it arrives in pristine, installation-ready condition anywhere in the world.
