Embraco Aspera Compressor FF8.5HBK

The Embraco FF8.5HBK is a hermetic reciprocating compressor designed for R134a refrigeration systems running in the LBP/MBP envelope. It’s a tidy, trade-friendly replacement for light commercial gear like display fridges, merchandisers and small coolrooms—stable in Aussie heat and built for dependable pull-down.

Features & Benefits

• R134a LBP–MBP envelope — suited to common cabinet and small coolroom duties when matched correctly, helping hold tighter case temps.
• 220–240V, 50Hz single-phase — straightforward fit on Australian mains with less messing around on site.
• 7.95 cm³ displacement (FF series) — a proven size for light commercial loads where efficiency matters.
• RSIR/CSIR motor platform — compatible with typical relay/overload and (where specified) start components for repeatable starts.
• Factory POE (ester) oil charge (ISO 22) — ready to install; keep it clean and dry for long service life.
• Fan-cooled shell — helps manage compressor temps in tight machinery spaces and hot plant rooms.

Who It’s For

Best suited to licensed refrigeration mechanics and HVAC-R techs doing like-for-like replacements on R134a systems (often capillary tube cabinets and small commercial setups). If the job is “get the cabinet cold again, properly, and keep it cold”, this model is a solid pick when the sizing and duty match.

Why This Compressor Matters

In the real world, call-backs usually come from the same culprits: tired start gear, moisture left in the system, or poor airflow through the condenser compartment. The FF8.5HBK gives you a reliable base—then your commissioning does the rest. Replace worn start components, change the drier, pull a proper vacuum, and you’ll typically see cleaner starts and steadier cabinet temps.

How to Use / Install

1. Confirm the match: refrigerant (R134a), duty (LBP/MBP), electrical (240V), and application (cabinet/coolroom).
2. Recover refrigerant safely using approved equipment and follow site isolation/lockout procedures.
3. Replace the filter drier and inspect capillary/TXV suitability (don’t assume it’ll “just work” if the old compressor was wrong).
4. Braze with nitrogen purge to keep scale out of the system.
5. Pressure test, then evacuate with a micron gauge (aim <500 microns plus a rise test).
6. Charge by weight, then verify operation (superheat, airflow, condenser condition, and current draw).

Limitations & Safety Notes

• Licensed trade installation only (refrigerant handling + electrical work).
• R134a only — do not use on R600a/isobutane systems or any other refrigerant unless the system is designed for it.
• POE oil is hygroscopic — keep shipping plugs in place until install, minimise exposure time, and always evacuate properly.
• Airflow is non-negotiable — blocked condenser compartments cook windings and oil. Fix airflow before you blame the compressor.

What’s Included

FAQs

Is FF8.5HBK suitable for R600a?
No — this model is specified for R134a. Use an R600a-approved compressor for isobutane systems.

Do I need to replace the relay/overload when changing the compressor?
Strongly recommended. RSIR/CSIR units rely on healthy start gear for clean starts and fewer nuisance trips.

What oil should I use?
Factory-charged with POE (ISO 22). If top-up is required, use an OEM-approved equivalent and keep moisture out.

Capillary or TXV?
Often capillary tube on small cabinets. Always verify sizing when replacing unlike-for-like compressors.
