Description
Built for tradies: The Embraco Aspera EMY6170Z is a hermetic reciprocating compressor for R134a systems in the LBP/MBP envelope. It’s a tidy swap for display fridges, merchandisers, vending and small coolrooms — quick to fit, stable in Aussie heat, and no dramas when you match the duty and commission it properly.
Features & Benefits
- LBP–MBP application (R134a) — suits common cabinet and reach-in duties to help hold product temps and cut call-backs.
- 220–240V, 50Hz single-phase — straightforward on Australian mains with less mucking around.
- ~1/4 HP class performance — a dependable option for light commercial loads when matched to the system.
- CSIR motor platform — designed to run with correct relay/overload and (where specified) a start capacitor for clean starts.
- Compact NEU/EM family form factor — easier handling in tight plant bays; bloody good for faster change-outs.
- Factory POE oil charge — ships ready to install; keep moisture out for long life.
Who It’s For
This compressor is for licensed refrigeration mechanics and HVAC-R techs replacing a failed unit in an R134a cabinet or small commercial application. It’s ideal when the job needs a like-for-like swap, and you want a proven platform that starts reliably and holds steady once the case has pulled down.
Why This Compressor Matters
When a merchandiser starts short-cycling on a hot day, it’s usually the compressor, start gear, airflow, or moisture contamination doing the damage. The EMY6170Z gives you a solid base — then your install quality does the rest. Replace tired start components, change the drier, pull a proper deep vacuum, and you’ll usually see fewer nuisance trips and more stable cabinet temps.
How to Use / Install
- Confirm the match: refrigerant (R134a), application (LBP/MBP), power (240V 1~), and that capacity/displacement suits the cabinet/coolroom.
- Recover refrigerant safely, isolate power, and inspect the compartment for airflow restrictions and heat damage.
- Replace the filter drier and keep the system sealed as much as possible (POE oil is hygroscopic).
- Nitrogen purge while brazing, then pressure test and leak check.
- Evacuate properly: use a micron gauge, aim <500 microns, and do a decay/rise test.
- Charge by weight, then confirm current draw, superheat, condenser cleanliness, and cabinet pull-down.

Limitations & Safety Notes
- Licensed installation only (refrigerant handling + electrical work).
- R134a only — not suitable for R600a/isobutane systems.
- Start gear must match — CSIR compressors depend on correct relay/overload and (where required) capacitor values.
- Airflow is non-negotiable — blocked condenser compartments cook oil and windings. Fix airflow before commissioning.
Compatibility & System Info
Refrigerant: R134a. Applications: LBP/MBP cabinets, merchandisers, small coolrooms, vending. Typical capillary systems; verify cap tube sizing if replacing a different model.
Local note: Coastal installs: protect terminals from salt creep. Inland/hot sites: keep coils and fan airflow clean — she’ll be right if it breathes.

FAQs
Is EMY6170Z suitable for R600a?
No — this model is specified for R134a. Use an R600a-approved model for isobutane systems.
Do I need new start gear?
Highly recommended. CSIR compressors depend on a healthy relay/overload (and capacitor where specified) to avoid nuisance trips.
What oil should I use?
Factory-charged with POE. If re-oiling, match the OEM ester grade and protect it from moisture.
