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). They are great for cold rooms, display fridges, bottle coolers, chest freezers, and food service equipment where uptime matters.
Why SECOP Compressors Matter
These compressors are essential for refrigeration mechanics and HVAC-R techs needing to replace a failed compressor or quote a repair on systems with remaining service life. For those maintaining cafés, pubs, supermarkets, prep kitchens, or small cold rooms, having access to this reliable range ensures quick turnarounds and sustained operational efficiency for your clients.
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.
Applications
- Cold rooms
- Upright fridges and merchandisers
- Bottle coolers
- Chest freezers
- Under-counter units
- Food service equipment
Choosing the Right Model
- 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.
Tradie Pro Tip
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.
Installation & Commissioning Guidelines (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).
Please note: We strongly recommend to consult with an HVAC technician for installation. You can also check this video guide for a brief overview on how to replace Secop Compressors:
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.
