About Copeland
Copeland manufactures scroll and reciprocating compressors for commercial refrigeration, air-conditioning, and heat-pump applications. The brand is recognized in industrial cooling for precision-engineered displacement series spanning 1.5 to 30 CV, covering small-capacity spot coolers through large modular systems. 3G Electric stocks Copeland's ZR and ZP scroll-compressor lines, all rated to 45 bar maximum service pressure and compatible with modern refrigerants including R450A, R513A, R407C, and R134a—critical for systems transitioning away from legacy HCFCs. Each unit is factory-tested for discharge and suction pressure performance; typical discharge ratings run 43–45 bar(g) against suction pressures of 20–29.5 bar(g), matching medium-to-high-capacity cooling loads in supermarket display cases, industrial process chillers, and packaged rooftop units. Copeland compressors are fitted with integral capacity modulation and thermal overload protection, allowing variable cooling output without external regulators. Supply voltages standardized at 380–420V 3-phase 50 Hz across the regional product range. 3G Electric maintains stock at its Woodlands warehouse and supports technical inquiries with baseline pressure-enthalpy data, refrigerant compatibility matrices, and installation guidelines. Typical lead times for in-stock SKUs are same-day or next-business-day fulfillment; custom displacement or voltage configurations require manufacturer lead time.
Frequently asked questions
Common questions about Copeland from 3G Electric.
Which refrigerants are compatible with Copeland ZR and ZP scroll compressors?
Copeland ZR-series (ZR-40, ZR-61, ZR-72, ZR-81) and ZP-series (ZP-61, ZP-103, ZP-137, ZP-182) compressors are rated for R450A, R513A, R407C, and R134a. R450A and R513A are low-GWP alternatives suited to modern environmental standards. Verify refrigerant charge and oil type with the unit nameplate before retrofit or commissioning.
What is the maximum service pressure rating for Copeland compressors in 3G Electric's stock?
All Copeland scroll compressors listed—ZR-40, ZR-61, ZR-72, ZR-81, ZP-61, ZP-103, ZP-137, and ZP-182—are rated to 45 bar maximum service pressure. Discharge pressures typically operate in the 43–45 bar(g) range; suction pressures range from 20 to 29.5 bar(g) depending on model and cooling load.
What displacement range does the Copeland scroll-compressor family cover?
Copeland's ZR and ZP series span 1.5 to 30 CV (cubic-volume displacement). The ZR-40 through ZR-81 models occupy the medium range; ZP-61 through ZP-182 are sized for higher-capacity systems. Displacement directly correlates to cooling capacity; selection depends on evaporator load and suction/discharge pressure conditions.
Are Copeland compressors pre-charged, and what electrical supply do they require?
Copeland compressors are factory-charged with specified POE or mineral oil and refrigerant. Electrical supply is standardized at 3-phase 380–420V 50 Hz across 3G Electric's range. Motor power ratings vary by model, from under 4 kW (ZP-61) to 5+ kW (ZP-182); verify nameplate amperage before panel integration.
Can Copeland compressors be used in retrofit applications replacing older reciprocating units?
Yes, Copeland scroll compressors offer higher isentropic efficiency and lower noise than legacy reciprocating designs, making them suitable for retrofit where space and electrical infrastructure permit. Confirm refrigerant compatibility, suction/discharge pressures, and motor supply match the existing system before substitution. Oil type may differ; consult installation documentation.
What noise levels are specified for Copeland ZP-series compressors?
The ZP-182 KCE model is rated at 22 dB(A), representative of modern scroll-compressor performance. Scroll design inherently produces lower noise than reciprocating units. Noise levels vary slightly by displacement and operating pressure; contact 3G Electric for full acoustic data on specific models.
