If you service or build R22-based air conditioning systems, the AAD201A027G compressor (50 Hz, 3-phase, 380-415 V) is one of the most practical replacement and OEM units available today. This guide gives you the complete technical picture: full specifications, real-world applications, sizing and compatibility checks, installation best practices, pricing, and answers to the questions buyers actually ask before ordering. It is written for HVAC contractors, refrigeration engineers, wholesalers, and OEM purchasing teams.
Quick Answer: What Is the AAD201A027G?
The AAD201A027G is a hermetic refrigeration compressor designed for air conditioning and commercial refrigeration duty on R22 refrigerant. It runs on 50 Hz three-phase power at 380-415 V, which makes it a direct fit for installations across Europe, the Middle East, Africa, Asia, and Latin America. Unit pricing runs from $429 to $530 depending on order volume, with a minimum order quantity of just one piece – which matters if you are a repair company that needs a single unit for an emergency job rather than a container load.

Why R22 Compressors Still Matter in 2026
R22 (HCFC-22) has been phased out of new equipment manufacturing in most developed markets, but the installed base is enormous. Across the Gulf states, Africa, South Asia, and much of Latin America, thousands of commercial AC systems, chillers, and cold-room condensing units still run on R22 and will for years to come. Every one of those systems eventually needs a compressor replacement.
This creates a specific procurement challenge: demand is shrinking but not gone, so many mainstream manufacturers have stopped producing R22 compressors, while service demand persists. Sourcing a dependable, fairly priced R22 unit from a specialist supplier is now the standard path for contractors in these regions. That is exactly the gap the AAD201A027G fills.
A practical note for engineers: before replacing a failed R22 compressor, check whether the system is a candidate for a refrigerant retrofit (such as R417A or R438A drops-ins). If the system is older, has recurring leaks, or the customer plans to keep it for many more years, retrofit economics may change the calculation. For straightforward like-for-like replacement, staying on R22 with a new compressor is the lowest-risk, lowest-cost option.
Performance and Design Characteristics
Three-phase efficiency at commercial scale
Three-phase motors deliver more torque per ampere of current than single-phase designs, run smoother, and start under load more reliably. For compressors in the AAD201A027G’s capacity class, three-phase 380-415 V is the industry-standard configuration – matching the supply available in virtually every commercial plant room.
Wide voltage tolerance
The 380-415 V rating band is not a typo; it is a design window. Grid voltage in real installations drifts: 380 V nominal in some countries, 400 V in others, 415 V in the UK-influenced markets, with sags and swells on top. A compressor engineered across that band tolerates the drift that kills marginal motors in the field, which is one of the most common causes of premature compressor failure in developing-market electrical environments.
50 Hz operation
Rated specifically for 50 Hz grids, the motor’s cooling, lubrication flow, and current draw are all optimized at this frequency. (See the FAQ for 60 Hz questions – the answer matters if you are buying for the Philippines, Saudi Arabia’s older networks, or the Americas.)
Application Scenarios: Where the AAD201A027G Works
Scenario 1: Commercial rooftop AC maintenance in R22-heavy regions
A facilities contractor in the Gulf, Africa, or South Asia services office buildings and retail blocks where 10-20 year old rooftop packaged units still run on R22. When a compressor fails in 45 C+ summer ambients, the customer needs the building cooling again within days, not weeks. The AAD201A027G’s 380-415 V tolerance absorbs the voltage sag common on heavily loaded commercial supplies in these markets, and its one-piece MOQ means the contractor orders exactly what the job needs – a like-for-like swap, back in service within the week.
Scenario 2: Medium-temperature cold rooms for food and floriculture
A cold room storing fresh produce, dairy, cut flowers, or pharmaceuticals at +2 to +8 C typically runs 14-18 hours per day with door-traffic load spikes during loading windows. The compressor sees sustained moderate load with periodic pull-down after deliveries – exactly the duty a robust fixed-speed R22 unit handles well. For operators of older R22 cold rooms, replacing a failed compressor at $429-530 is a fraction of the cost of converting the whole system to a new refrigerant, and keeps the storage running while conversion is planned properly.
Scenario 3: Small industrial process chillers on R22
Plastic molding shops, small chemical processors, and printing operations often run compact water chillers charged with R22 to hold process water temperature. These chillers run long steady hours – the kindest duty profile for a fixed-speed compressor – and their owners are highly cost-sensitive on parts. The AAD201A027G gives maintenance teams a factory-priced, correctly-rated replacement that keeps legacy cooling circuits in service without re-engineering.
Scenario 4: OEM assembly for R22-permitted markets
In jurisdictions where R22 equipment assembly remains legal for domestic sale, condensing-unit and packaged-AC builders need a dependable R22 compressor supply at OEM volumes. Consistent factory quality, export documentation, and scheduled deliveries make the AAD201A027G a practical production line choice, with tiered volume pricing available on contract.
Compatibility Checklist Before You Order
Compressor replacement failures are almost never the compressor’s fault – they are mismatches and installation errors. Work through this list before placing any order:
- Refrigerant type: confirm the system charge is R22 and that no retrofit blend has been introduced.
- Electrical supply: verify nameplate voltage (380/400/415 V), phase count, and 50 Hz frequency at the unit, measured under load – not just on paper.
- Capacity match: compare the old compressor’s displacement or BTU/h rating; going oversized causes cycling and oil return problems.
- Suction and discharge line sizes: line diameters must match or be adapted by a licensed technician; mismatches cause velocity and oil-return faults.
- Mounting and footprint: confirm base isolators and bolt pattern fit the existing frame.
- Electrical connections: terminal type, crankcase heater provision, and contactor/overload ratings.
- System cleanup: after a motor burnout, install a filter-drier (possibly two in series for severe burnouts) and flush or replace contaminated components. A new compressor on a dirty system will fail again.
Installation Best Practices
Treat the new compressor as the most expensive component in the system and protect it:
- Braze with nitrogen flowing through the lines to prevent internal oxide scale.
- Pull a deep vacuum – below 500 microns, held with a decay test – before charging. Moisture and non-condensables destroy valves and oil.
- Charge by weight using the system’s design charge, then fine-tune superheat/subcooling measurements.
- Check phase rotation on first start-up; a reversed-phase compressor pumps backwards and fails quickly.
- Energize the crankcase heater (if fitted) for several hours before start-up to boil refrigerant out of the oil.
- Log running data – suction pressure, discharge pressure, superheat, subcooling, and amps – as a commissioning baseline for future service.
Price, MOQ, and How to Buy
The AAD201A027G is priced between $429 and $530 per unit with a one-piece minimum. Where you land in that range depends on order quantity, destination, and current factory scheduling. For wholesalers and OEMs placing volume orders, tiered pricing applies – request a formal quotation with your target quantity.
Every unit ships factory-tested with protective packaging suited to international freight. Air express is typical for urgent single-unit orders; sea freight consolidations make sense for bulk.

Frequently Asked Questions
Can the AAD201A027G run on a 60 Hz supply?
Not recommended. On 60 Hz a 50 Hz-rated compressor runs 20% faster, which raises current draw, changes capacity and oil behavior, and voids the operating envelope it was engineered for. For 60 Hz markets, ask the team for the 60 Hz variant.
Is R22 still legal to use?
Rules vary by country. In most regions, servicing existing R22 equipment with reclaimed or virgin stock remains permitted even as new-equipment manufacture is banned. Always confirm your local refrigerant regulations before ordering.
What does it cost shipped to my country?
Landed cost = unit price ($429-530) + freight + duties. Request a quotation with your destination port or airport for an all-in figure.
How long does delivery take?
In-stock singles typically ship within 3-7 working days by air express; bulk orders run 2-4 weeks depending on quantity and factory scheduling.
Is there a warranty?
Yes, units carry a manufacturer warranty. Warranty claims require evidence of correct installation (vacuum records, charge weight, electrical data) – which is standard industry practice.
Can it replace any R22 compressor of similar size?
Not automatically. Capacity, voltage, and pipe connections must align. Send the old nameplate details for a free interchange check.
