06TSA186 75HP Air-Cooled Screw Refrigeration Compressor

The 06TSA186 is a heavy-duty 75 HP screw refrigeration compressor belonging to Carlyle's Paragon 06TS series, specifically engineered for high-capacity air-cooled chillers, commercial HVAC central plants, and process cooling systems. Featuring patented twin-screw rotor geometry produced with state-of-the-art manufacturing processes, it delivers steady gas compression and high volumetric efficiency with eco-friendly R134a refrigerant. Built-in volume ratio (Vi) compensation during part-load operations allows the compressor to maintain optimum thermodynamic efficiency across widely varying ambient outdoor temperatures.

Designed for long continuous run cycles under severe industrial loads, this screw refrigeration compressor utilizes high-precision rolling element bearings within a sealed cavity structure to reduce mechanical load and wear. Operating without an external oil pump, its differential pressure lubrication circuit feeds internal bearing galleries reliably. Internal safeguards include a fast-closing check valve to prevent reverse rotor rotation upon system shutdown, fine-mesh suction strainers, and high-efficiency discharge muffling to lower dynamic pressure pulsations and operating sound levels.

To reduce initial starting current and minimize power grid disturbance, the unit features automatic unloaded starting and continuous capacity unloading down to 25% of full load. Driven by a high-efficiency suction-cooled motor with embedded NTC thermistors in the winding heads for thermal overload protection, the compressor easily integrates into 50Hz and 60Hz global electrical power systems. Housed in a durable 393 kg chassis, it offers standard mounting footprints and flanged connection ports for efficient OEM skid assembly and drop-in field replacement.
