Who it’s for: Refrigeration techs, apprentices and contractors who need a fair dinkum 1HP class, medium-back-pressure (MBP) hermetic for R404A systems—reliable starts, correct oil, and fewer call-backs.
Key Features & Benefits
- 1 HP class / 22.4 cm³ displacement – Solid pull-down for MBP cases and coolrooms, so you clear jobs faster.
- CSR/CSIR high-start torque motor – Confident hot restarts on busy sites; less fiddle, less downtime.
- POE ISO22 oil, 450 ml charge – Right viscosity from factory for R404A MBP work; protects bearings and reduces wear.
- 220–240 V, 50 Hz (single-phase) – Plug-and-play for Australian sites; no special power requirements.
- -20°C to +10°C evap envelope (MBP) – Covers common commercial refrigeration temps without drama.
- Compact form factor (≈234 mm height) – Easy swaps in tight cabinets; keeps change-outs no worries.
- Embraco NT platform – Trusted build quality that means fewer surprise come-backs.
Why This Compressor Matters
Last week on a suburban bottle-shop in Brisbane we swapped a tired MBP can for an NT6226GK. Brazed, nitrogen-swept, evacuated, weighed in R404A, and it was pulling down nicely before lunch. That’s the difference when your can has the right torque profile and oil straight out of the box—clean starts, stable amps, happy client. If you’re speccing cases or doing like-for-like coolroom swaps, this unit is a bloody good choice for dependable MBP performance.

Pro Tip
Match the oil viscosity and refrigerant to the application envelope. The NT6226GK ships with POE ISO22. If you’re retrofitting from mineral or AB oils, use a proper procedure (flush or chemical transition) before button-up to avoid miscibility issues. Always evacuate to your microns target and break with dry nitrogen before charging.
Compatibility & System Info
- Primary refrigerant: R404A (MBP application).
- Envelope-dependent blends (check selection): Some distributors list use with R507A/R452A and others; always confirm against Embraco’s application data before commissioning.
- Use cases: Coolrooms, display cases, under-bench fridges (MBP).
- Power: 220–240 V, 50 Hz, 1-phase; CSR/CSIR motor.
Local note: On Perth rooftops in 40°C ambient or humid Brisbane plantrooms, give yourself headroom: weigh charges, verify SH/SC, and confirm airflow across condensers so the can stays in its happy zone.

FAQs
- Can I use this can on R134a?
- The NT6226GK is specified for R404A MBP. If your application is R134a, consider an Embraco NEU model (e.g., NEU6215GK) and always confirm envelopes and duty.
- What oil should I stock for top-ups?
- POE ISO22 only for this model. Don’t mix viscosities. If converting from mineral/AB, use a proper retrofit process to avoid oil/refrigerant miscibility issues.
- Do I need a start relay/capacitor?
- Yes—this is a CSR/CSIR motor. Use an appropriate start relay and capacitor per Embraco’s component kit and wiring diagram for the exact variant.
- What commissioning tools do I need?
- At minimum: manifold/digital gauges, nitrogen for pressure testing, micron gauge, and a reliable vac pump. See our vacuum pump range for options.
