Why decoding matters
Buyers rarely know the exact part number they need. They have a nameplate photo, a capacity and a refrigerant. Knowing how each brand encodes horsepower, refrigerant and voltage lets you identify the right unit in minutes instead of days.
GMCC rotary (PH series)
The PH prefix identifies the rotary platform; the following numbers indicate the displacement or capacity class, X denotes the refrigerant design, and the suffix group encodes voltage, frequency and motor arrangement. Practically: PH135 ≈ 1 HP, PH150 ≈ 1.5 HP, both R410A. The trailing -4P3 style suffix usually encodes supply and phase.
Suffix meanings can vary by generation — we verify the exact configuration against the batch datasheet for every supply.
Copeland scroll (ZR / ZP)
The letter pair indicates the family (ZR for R410A scroll, ZP for A/C scroll variants), the number approximates the nominal capacity in thousands of BTU/h, and the remaining letters define motor protection, phase and the electrical code. ZP24 ≈ 24,000 BTU/h (2 HP); ZR34 ≈ 36,000 BTU/h (3 HP).
Embraco / Aspera hermetic units
The first digits encode capacity class, the following letters encode the application range: N denotes standard efficiency, E denotes higher efficiency. The back-pressure class is the critical part — LBP for freezers, MBP for fridges, HBP for beverage coolers and display cases.
Maneurop MT scroll
MT followed by a number gives the displacement class; the next letters indicate motor version and application. MT64 indicates a mid-size unit suited to cold rooms and medium-temperature condensing units.
Still unsure?
Send us a clear photo of the nameplate plus the refrigerant and supply voltage. We cross-reference it and return the correct part number with a quotation — no obligation.
