Carrier 06TUW483 160HP Semi Hermetic Screw Air Conditioning Compressor
High-performance screw compressor designed for large-scale water chiller plants and commercial HVAC systems.
High-Displacement Efficiency for Large Water Chiller Plants
Designed for high-tonnage central water-cooled chillers, commercial HVAC loops, and process fluid cooling plants, the 06TUW483 screw air conditioning compressor delivers massive volumetric displacement while maintaining low energy consumption. Engineered for eco-friendly R134a, this 160 HP compressor produces 809 m³/h (483 CFM) at 60Hz and 670 m³/h (403 CFM) at 50Hz. By capitalizing on the low condensing lift of water-cooled systems, it draws significantly less electrical power (99 kW @ 50Hz / 119 kW @ 60Hz) while an integrated 1-5/8 in. economizer loop boosts liquid subcooling during high-duty cooling cycles.
Deep Turndown Capacity Modulation (Down to 15%)
To handle extreme load variations across multi-tenant commercial towers or industrial facilities, the 06TUW483 offers an expanded stepless modulation range of 25%-100%, or up to a deep turndown of 15%-100%. This continuous fluid unloading allows chiller systems to match light nighttime or off-season cooling loads without staging off the unit. By avoiding frequent start-stop cycles, the compressor dramatically raises Integrated Part Load Value (IPLV) and protects power electronics from current surges.
Engineered Flow Dynamics & Integrated Safeguards
Weighing 915 kg, the heavy-cast housing suppresses vibration and mechanical noise in indoor mechanical rooms. Internal differential pressure lubrication continuously protects precision SKF/NSK rotor bearings without requiring a motorized external oil pump.
High-Volume Interface Porting: Oversized 5-inch suction and 4-1/8 inch discharge ports prevent gas velocity bottlenecks and line pressure loss.
Discharge Gas Check Valve: Stops high-pressure refrigerant backflow from reversing twin-screw rotation during shutoff.
Direct Thermal Protection: Embedded winding thermistors monitor motor operating temperatures against phase loss and thermal overloads.
Standard & Optional Package Setup
Standard Assembly: Junction Terminal Box, Solenoid Modulation Valve Group, Internal Lubrication Network, Motor Protection Relay, Suction & Discharge Shutoff Valves.

Frequently Asked Questions
Q1: How does the 06TUW483 achieve 809 m³/h displacement with only 160 HP compared to air-cooled models?
Water-cooled condensing systems operate at lower condensing pressures than air-cooled units. This reduced pressure lift allows a 160 HP motor (drawing 119 kW @ 60Hz) to deliver the same high volumetric displacement (809 m³/h) that would require 225 HP on an air-cooled system.
Q2: What is the advantage of the extended 15%-100% capacity modulation range?
Standard compressors unload down to 25%. The 15% minimum modulation on the 06TUW483 allows chillers to stay online during periods of low cooling demand (such as cool nights or low building occupancy), preventing short-cycling and saving energy.
Q3: Why is an enlarged 5-inch suction connection used on this unit?
At a displacement of 809 m³/h, suction gas volumes are massive. The 5-inch connection reduces suction line fluid friction, keeping inlet pressure losses low and maximizing compressor operating efficiency.
Q4: What starting method is recommended for this 160 HP compressor?
Star-Delta starting is strongly recommended. On a 460V 60Hz power supply, Star-Delta starting drops locked-rotor current from 1270A down to 408A, protecting building electrical infrastructure from voltage dips.
Q5: How is the unit protected during long-distance ocean shipping?
Every compressor undergoes thorough vacuum dehydration, pressure leakage testing, and dry nitrogen charging. It is then wrapped in moisture-barrier packaging and bolted inside a reinforced, heavy-duty export plywood enclosure.
