Carlyle 06TTA356 R134a Industrial Twin-Screw Air Conditioning Compressor

Designed for top-tier commercial chillers, process cooling plants, and district cooling systems, the 06TTA356 screw air conditioning compressor delivers an impressive volumetric displacement of 596 m³/h (356 CFM) at 60Hz and 494 m³/h (296 CFM) at 50Hz. Driven by a robust 150 HP motor and optimized specifically for R134a refrigerant, this heavy-duty unit easily handles severe thermal demands. Its integrated 1-3/8 in. economizer subcooling port maintains high thermodynamic efficiency even when outdoor ambient temperatures force high head pressures across air-cooled condensers.

Fluctuating cooling demands are handled effortlessly through a high-precision dual-solenoid capacity control system. Providing continuous, stepless unloading from 25% up to 100%, the compressor dynamically matches real-time facility loads. This eliminates the energy spikes and mechanical stress caused by cycling large motors on and off, boosting seasonal performance metrics (IPLV) and maintaining steady chilled water loop temperatures.

Engineered with a heavy-cast 662 kg housing, the 06TTA356 screw air conditioning compressor minimizes operational sound and structural vibration transmission. Its internal pressure-differential oil system lubricates precision SKF/NSK rotor bearings continuously without requiring an external oil pump. Crucial structural safeguards include:

• Generous Fluid Passages: Oversized 4-1/8 in. suction and 3-1/8 in. discharge connections keep gas velocities balanced and line pressure drops low.
• Internal Gas Reverse Protection: A built-in discharge check valve stops backpressure from driving the twin screws in reverse during shutoff.
• Overheat Safeguards: Direct-embedded motor winding thermistors protect against electrical phase imbalance and high discharge gas temperatures.

• Standard Package: Motor Terminal Box, Solenoid Control Assembly, Internal Lubrication Circuit, Motor Protection Relay, Suction & Discharge Shutoff Valves.
• Optional Add-Ons: Economizer Heat Exchanger Assembly, External Oil Separator, Auxiliary Oil Cooler, Companion Flanges, Advanced Kriwan Diagnostic Modules.

Ruifujie brings over two decades of specialized manufacturing and engineering experience to the global refrigeration and air conditioning market. We produce a complete line of high-performance screw, scroll, reciprocating, and rotary compressors, as well as customized fluid chillers and modular cold storage solutions. Backed by rigorous factory quality inspections and full OEM/ODM capabilities, Ruifujie partners with contractors, system integrators, and equipment distributors across North America, Europe, the Middle East, and Asia to deliver dependable cooling technology at factory-direct value.

Using eco-friendly R134a paired with an active economizer circuit, the compressor subcools liquid refrigerant before it enters the evaporator. This process recovers cooling capacity that would otherwise be lost to high head pressures on hot days.

Star-Delta starting is highly recommended. For example, on a 460V 60Hz grid, Star-Delta starting reduces the locked-rotor current from 1190A down to 382A, preventing voltage drops across building electrical mains.

Yes. Its compact semi-hermetic profile, standard port dimensions, and flexible mounting footprint make it an ideal choice for dual- or triple-circuit air-cooled liquid chillers requiring independent circuit redundancy.

Because the unit uses differential pressure lubrication, routine maintenance focuses primarily on inspecting the external oil filter and checking oil clarity during annual service checks. No mechanical pump maintenance is required.

Every unit is thoroughly dehydrated, pressure-tested with dry nitrogen, sealed, and packed inside a heavy-duty, moisture-proof export wooden crate designed for safe forklift handling and overseas container transport.
