SECOP hermetic compressors are a trade-ready choice for commercial refrigeration in Australia. Pick the right LBP (low temp) or MBP (medium temp) duty, match the refrigerant, and you’ll get steady pull-down and fewer call-backs in the real world.
This range suits common 220–240V single-phase installs and covers R404A (low & medium temp) plus R134a (medium temp) across 1/3HP to 1.5HP (model dependent). Great for cold rooms, display fridges, bottle coolers, chest freezers and food service gear where uptime matters.
Key Features & Trade Benefits
- LBP + MBP line-up (1/3–1.5HP) — match the duty to the cabinet for cleaner pull-down and fewer “it’s running warm again” call-backs.
- Refrigerants: R404A & R134a — proven options for many commercial fridges, merchandisers and freezers (select the correct model).
- 220–240V single-phase — suits Australian mains without messy workarounds.
- Hermetic, compact footprint — easier swaps in tight cabinets and some mobile/plant setups.
- Built for service life — a solid pick for hot plant rooms, roof decks and busy kitchens.
Who It’s For
These compressors are for refrigeration mechanics and HVAC-R techs replacing a failed compressor or quoting a repair where the system still has life left in it. If you’re maintaining cafés, pubs, supermarkets, prep kitchens or small cold rooms, this is the kind of range you keep in mind for quick turnarounds.
How to Choose the Right Model (Quick Checklist)
- Match the application: Freezers / deep-freeze = LBP. Fridges / merchandisers / bottle coolers = MBP.
- Match the refrigerant: Choose R404A or R134a to suit the system design (don’t mix refrigerants).
- Confirm electrical: Check 220–240V, single-phase and compare current draw to the original nameplate.
- Check the cabinet setup: Cap tube / orifice / TXV must suit the duty and capacity.
- Start gear: Reuse or replace the correct relay/overload/capacitor setup as required by the model and site conditions.
Tip: If you’re unsure, take a clear photo of the old compressor nameplate and message our team—we’ll help you match it properly.

Please note: We strongly recommend to consult with an HVAC technician for installation.
How to Install & Commission (Licensed Trade)
- Recover refrigerant using approved equipment and follow safe handling practices.
- Isolate power, confirm lockout, and inspect wiring/start components before removal.
- Replace the filter drier and assess cap tube/orifice/TXV suitability for the new compressor duty.
- Braze with nitrogen purge to minimise scale and keep the system clean.
- Pressure test, then evacuate properly with a micron gauge (<500 microns is a good target) and perform a rise test.
- Charge by weight, then verify operation (superheat/subcooling, airflow, condenser condition, and current draw).
Limitations & Safety Notes
- Licensed installation only. Compressor replacement involves refrigerant handling and electrical work.
- Use only the selected refrigerant model. This page covers variants within the SECOP range—always confirm the exact selection before install.
- Not a “universal swap”. Capacity, duty (LBP/MBP), start gear, and metering device must match the system design.
- Moisture and contamination kill compressors. If the burnout was severe, take extra steps to clean the system and protect the new compressor.
Compatibility & System Info
- Applications: Cold rooms, upright fridges, merchandisers, bottle coolers, chest freezers, under-counter units.
- Refrigerants: R404A (LBP & MBP variants), R134a (MBP variants) — select the correct option.
- Electrical: 220–240V, single-phase (model dependent).
- Duty: LBP (low temp) & MBP (medium temp).
Local note: For Sydney summers and Perth warehouse installs where ambient temps spike, condenser airflow needs to be A-grade. Dirty coils = high head pressure = short compressor life. Keep it clean and re-check superheat after pull-down.

FAQs
Q: How do I pick between LBP and MBP?
A: Freezers and deep-freeze = LBP. Fridges, merchandisers, bottle coolers = MBP. Match the original duty whenever possible.
Q: Will this run on 220–240V single-phase?
A: This range is built for common AU mains. Always confirm the selected model’s nameplate and current draw before install.
Q: Do I need extra start components?
A: Some sites benefit from start assist (long lines, voltage sag, hot restarts). Match the required relay/overload/capacitor setup for the model and job conditions.
Q: Can I use this with R32?
A: No, choose a compressor designed and rated for the refrigerant used in your system. This page is for R404A/R134a variants within the SECOP range.
