Copeland ZR125KCE Commercial AC/Chiller Scroll Compressor
Overview
The Copeland ZR125KCE is a hermetic scroll compressor from the widely deployed Copeland Scroll ZR/ZRKC commercial air conditioning and process/precision cooling range, delivering roughly 125,000 BTU/hr (10-ton class) nominal cooling capacity in a compact, vertically oriented hermetic shell. Built on Emerson’s Copeland Scroll technology, it is used across commercial and light-industrial rooftop units, chiller packages, and process cooling skids wherever a reliable, efficient fixed-capacity compressor is needed for R22, R407C, or R134a service depending on variant.
As a supplier of Copeland (Emerson) products, Seven Star LLC supplies the ZR125KCE scroll compressor to HVAC contractors, chiller OEMs, and facilities engineering teams across Oman, Muscat, and the wider GCC, supporting every unit with manufacturer documentation and application selection support.
Operating Principle
The Copeland ZR125KCE compresses refrigerant vapor using two interleaving spiral (scroll) elements – one fixed, one orbiting – that trap and progressively shrink a series of crescent-shaped gas pockets as the orbiting scroll moves. This continuous, smooth compression path produces very low pulsation and vibration compared with reciprocating compressors, and the design inherently tolerates small amounts of liquid refrigerant or debris passing through the compression chamber without the valve or piston damage a reciprocating machine would suffer under the same conditions.
Because scroll compression has fewer moving parts and no suction or discharge valves to wear or fail, the ZR125KCE delivers high volumetric and mechanical efficiency across its operating envelope, along with quieter operation and reduced maintenance relative to older reciprocating compressor technology performing an equivalent cooling duty. The hermetic shell fully encloses the motor and compression elements, eliminating shaft seal leak paths and keeping the refrigerant circuit sealed for the compressor’s service life.
Engineering Design of the Copeland ZR125KCE
The Copeland ZR125KCE uses a vertical hermetic shell construction typical of the Copeland Scroll ZR/ZRKC family, with the scroll compression elements mounted above an internal induction motor and oil sump, and a discharge muffler integrated into the shell to reduce discharge gas pulsation before it reaches the system piping. The compressor terminal box houses the motor protection module and electrical terminals, and copper suction and discharge stub connections allow direct brazing into the refrigerant circuit without additional adapter fittings.
Variants of the ZR125KCE are offered for different refrigerants (R22, R407C, R134a) and voltage/phase combinations (such as 380-420V/3-phase or 200-230V/3-phase, 50/60 Hz) to match the electrical supply and refrigerant charge used in a given regional installation, and Seven Star LLC helps customers confirm the correct suffix code for their specific system before ordering. Internal motor protection, crankcase heater provision, and a factory oil charge are standard across the ZRKC family, simplifying field commissioning.
Key Features
The Copeland ZR125KCE brings proven Copeland Scroll reliability to 10-ton class commercial cooling duty. Key features include:
- Scroll compression technology with continuous, low-vibration gas compression and no suction/discharge valves.
- Approximately 125,000 BTU/hr nominal cooling capacity for commercial AC and process/precision cooling systems.
- Available in R22, R407C, and R134a refrigerant variants to match existing or upgraded system charges.
- Hermetic shell construction eliminates shaft seal refrigerant leak paths for a fully sealed circuit.
- Integrated discharge muffler reduces gas pulsation and downstream vibration in the piping system.
- Internal motor protection module and factory oil charge simplify commissioning and field wiring.
- Tolerant of minor liquid slugging and particulate compared with reciprocating compressor designs.
- Multiple voltage/phase configurations available (e.g. 380-420V/3-ph, 200-230V/3-ph) for regional electrical standards.
Industrial Applications
The Copeland ZR125KCE is widely used across Oman’s commercial building, hospitality, and light-industrial sectors, including rooftop package air conditioning units for hotel and retail complexes, central chiller plants serving hospital and office towers, and process cooling skids supporting light manufacturing in the Sohar and Salalah economic zones. Its 10-ton nominal capacity makes it a common building-block compressor for multi-circuit chiller and condensing unit designs, where several ZR125KCE units are staged together to match variable building cooling loads.
As the trusted supplier for Copeland (Emerson), Seven Star LLC supplies the ZR125KCE to HVAC contractors, OEM chiller manufacturers, and facilities maintenance teams across Oman and the GCC, supplying genuine compressors matched to the correct refrigerant, voltage, and application duty for each installation.

Copeland compressor models listed here
The page lists the Copeland ZR125KCE scroll compressor for commercial air conditioning and chillers, and two semi-hermetic reciprocating compressors: the D3DS5-1500 and the DWM Copeland D8SJ1-600X. An Alco 240RA series two-way, normally closed solenoid valve for refrigerant lines is listed with them.Ordering a Copeland compressor: what we need
Copy the complete model number and the serial number from the nameplate. The letters after the capacity digits and the motor code after the dash define the oil type and the electrical supply, so ZR125KCE-TFD is not the same item as another ZR125 variant. Add the refrigerant, the supply voltage, phase and frequency, and say whether the application is air conditioning or medium or low temperature refrigeration. For semi-hermetic models, mention the motor protection module and any unloaders or oil pump fitted. We quote to buyers across the GCC from this data.Browse Copeland products by category: Compressor, Cooling, Solenoid Valve.
