06TVW680 Carlyle Water-Cooled Screw Refrigeration Compressor for AC Rack System

Designed for high-tonnage central liquid chillers, district cooling systems, and large-scale industrial process cooling, the 06TVW680 screw refrigeration compressor delivers massive volumetric throughput with outstanding thermodynamic efficiency. Operating on eco-friendly R134a refrigerant, this 225 HP unit produces an impressive displacement of 1133 m³/h (680 CFM) at 60Hz and 944 m³/h (567 CFM) at 50Hz. Utilizing stable water-cooled condensing temperatures allows the compressor to achieve exceptional mass flow at lower power consumption, while an integrated 1-5/8 in. economizer subcooling port maximizes cooling capacity during heavy thermal loads.

To handle extreme load fluctuations across commercial complexes or industrial manufacturing processes, the 06TVW680 features a dual-solenoid stepless capacity modulation system covering 25%-100%, with an extended deep-turndown option down to 15%-100%. This continuous fluid adjustment enables central plants to match light nighttime or partial-occupancy cooling demands without stopping the compressor. By eliminating frequent motor start-stop cycles, the unit optimizes Integrated Part Load Value (IPLV) and protects power distribution networks from current surges.

Weighing 1173 kg, the heavy-cast semi-hermetic housing acts as a solid mass dampener, suppressing mechanical noise and vibration in indoor plant rooms. The compressor operates via an internal pressure-differential lubrication scheme, continuously supplying lubricant to precision SKF/NSK rotor bearings without requiring a motorized external oil pump.

• High-Flow Line Connections: Massive 5-inch suction and 4-1/8 inch discharge ports reduce gas velocity restrictions and keep system manifold pressure losses minimal.
• Integrated Check Valve: Prevents high-pressure discharge gas backflow from driving the twin screws in reverse upon shutoff.
• Winding Thermal Protection: Embedded NTC thermistors continuously monitor motor temperatures to protect against phase imbalance and electrical overload.

• Standard Package: Terminal Connection Box, Capacity Modulation Solenoid Valve Group, Internal Lubrication Network, Motor Protection Relay, Suction & Discharge Service Valves.
• Optional Equipment: Economizer Subcooling Plate Exchanger, High-Efficiency External Oil Separator, Auxiliary Liquid Oil Cooler, Companion Flanges, Advanced Diagnostic Protection Modules.

Delivering a high displacement of 1133 m³/h at 60Hz, a single 06TVW680 unit supplies massive mass flow for multi-megawatt water chillers. This allows equipment manufacturers to achieve high tonnage ratings while reducing total compressor count and simplifying piping manifolds.

Standard screw compressors unload down to 25%. The 15% minimum turndown capability on the 06TVW680 allows central chillers to remain online during periods of low cooling demand, eliminating energy-intensive start-stop cycles.

Star-Delta starting is strongly recommended. For example, on a 460V 60Hz supply, Star-Delta starting drops locked-rotor inrush current from 1800A down to 578A, protecting site transformers and preventing main board voltage dips.

Yes. The 1173 kg cast housing provides heavy structural dampening, but mounting the compressor on a rigid steel skid equipped with heavy-duty anti-vibration isolation pads is recommended to isolate low-frequency vibration from plant room floors.

Each compressor undergoes full vacuum dehydration, pressure leakage testing, and dry nitrogen pre-charging. It is sealed inside a multi-layer moisture barrier foil and secured within a heavy-duty, reinforced export plywood skid engineered for crane and heavy forklift handling.
