Quick answer: The Copeland ZR250KCE-TED-522 is a 20 HP three-phase scroll compressor for air conditioning, chillers and rooftop units. Copeland’s published 50 Hz data for the same platform (ZR250KCE-TWD-522) gives a displacement of 56.6 m³/h and a cooling capacity of 52.2 kW. The nominal capacity at 60 Hz is about 250,000 BTU/h. It has brazed 1-5/8 inch suction and 1-3/8 inch discharge connections, POE oil, and approved refrigerants R22, R407C and R134a. Before ordering in the UAE, confirm the complete electrical code and nameplate details: voltage, frequency and motor protection.
What Is the Copeland ZR250KCE-TED-522?
It is a hermetic scroll compressor from Copeland’s ZR range. Two spiral scrolls, one fixed and one orbiting, compress the gas, so there are no suction or discharge valves. The model code reads as Z for scroll, R for air conditioning, 250K for a nominal capacity of about 250,000 BTU/h, E for POE oil and T for three-phase. It can also be paired in tandem or trio setups.
What Are the Specifications?
Most figures below come from Copeland’s published listing for the ZR250KCE-TWD-522, the same mechanical platform. Connection sizes and oil charge come from supplier listings. Electrical and motor-protection details can differ between the TED and TWD versions, so confirm them against the exact TED-522 data sheet before you rely on them.
50 Hz rating data (Copeland listing for ZR250KCE-TWD-522, R407C, 5 °C evaporating, 50 °C condensing, 50 Hz)
| Specification | Value |
|---|---|
| Displacement | 56.6 m³/h |
| Cooling capacity | 52.2 kW (about 178,000 BTU/h) |
| Power input | 16.25 kW |
| COP | 3.21 |
| Maximum current | 42 A (TWD-522 listing; confirm for TED-522) |
Nominal 60 Hz capacity
| Specification | Value |
|---|---|
| Nominal cooling capacity | About 250,000 BTU/h |
General and platform data (confirm against the TED-522 data sheet)
| Specification | Value |
|---|---|
| Refrigerants | R22, R407C, R134a |
| Nominal power | 20 HP |
| Suction / discharge | 1-5/8 in / 1-3/8 in |
| Oil | POE, about 4.7 L |
| Dimensions (W×L×H) | 376 × 427 × 726 mm |
| Weight | 138.8 kg |
| Max pressure (low/high) | 20 / 32 bar(g) |
| Voltage code D | 380–420 V 3 Ph 50 Hz; 460 V 3 Ph 60 Hz |
| Enclosure | IP54 (TWD-522 listing; confirm for TED-522) |
| Motor protection | Differs by code letter (E or W); confirm on the TED-522 data sheet |
| Sound power | 88 dBA (listed separately; rating condition not stated, so do not compare it with the 50 Hz data above) |
Why do capacity figures differ? The 250,000 BTU/h figure is a nominal 60 Hz capacity. Copeland’s 52.2 kW, about 178,000 BTU/h, is at 50 Hz and the rating condition shown above. Keep 50 Hz and 60 Hz data separate, and compare capacity only at the same frequency and conditions. Always check the nameplate of the unit you are replacing.
TED or TWD: What Is the Difference?
In Copeland’s model nomenclature, the D voltage code covers 380–420 V 3 Ph 50 Hz and 460 V 3 Ph 60 Hz. Both TED and TWD carry the D code, so frequency is not what separates them. The E and W letters refer to different motor protection types. UAE three-phase supply is 400 V at 50 Hz, which sits within the D code range.
Do not guess from the model name. Confirm the frequency, voltage and motor protection from the complete electrical code on the existing nameplate, or ask for the data sheet. Some suppliers also list ZR250KCE-TED-951 as an alternative. The 522 and 951 are different BOM variations, so do not treat the 951 as a direct replacement unless Copeland’s official cross-reference confirms it.
Why Use a Scroll Compressor for Air Conditioning?
Copeland highlights axial and radial compliance, low sound and vibration, and a low oil circulation rate. In practice, a scroll has fewer moving parts than a reciprocating compressor and runs smoothly, which suits plant rooms and rooftops where noise and reliability matter. A sound power figure of 88 dBA is listed for this model, so plan mounting and pipe supports and check the rating condition on the data sheet.
Where Is It Used?
Commercial air conditioning, chillers, rooftop packaged units and precision cooling. It is an air-conditioning duty compressor. The +5 °C evaporating temperature in the rating data is a rating condition, not a fixed operating point, and actual operation must stay within Copeland’s published operating envelope. It is not intended for low-temperature cold rooms or freezers.

Frequently Asked Questions
What refrigerants does the ZR250KCE-TED-522 use? R22, R407C and R134a, with POE oil.
How many HP is it? It is a 20 HP compressor.
Is it suitable for refrigeration? No. It is built for air conditioning and chillers, not low-temperature refrigeration.
Can it replace a ZR250KCE-TWD-522? Only if the complete electrical code, voltage, frequency, motor protection and connections match. TED and TWD differ in motor protection type, so check the nameplate and data sheet first.
What is the maximum operating current? 42 A, per Copeland’s listing for the TWD-522 at 50 Hz. Confirm the TED-522 figure on its data sheet.
How heavy is it? About 139 kg, so plan lifting equipment.
