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

1. Confirm the match: refrigerant (R134a), application (LBP/MBP), power (240V 1~), and that capacity/displacement suits the cabinet/coolroom.
2. Recover refrigerant safely, isolate power, and inspect the compartment for airflow restrictions and heat damage.
3. Replace the filter drier and keep the system sealed as much as possible (POE oil is hygroscopic).
4. Nitrogen purge while brazing, then pressure test and leak check.
5. Evacuate properly: use a micron gauge, aim <500 microns, and do a decay/rise test.
6. 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.
