Description
Embraco NEK6181GK Medium Temp Compressor (1/3 HP, R-404A)
When a commercial display fridge, blast chiller, or cool room goes down, your client is racing against the clock before premium stock spoils. You need a replacement that drops in easily, pulls down fast, and runs reliably under heavy loads. The Embraco NEK6181GK is a hermetic reciprocating compressor designed specifically for Medium Back Pressure (MBP) applications[cite: 1]. It operates on a 220-240 V 50 Hz power supply and is approved for use with R-404A refrigerant[cite: 1].
Key Features & Trade Benefits
- R-404A Optimized: Engineered explicitly for R-404A, offering robust thermodynamic performance and operating within an evaporating temperature range of -20 °C to 10 °C[cite: 1].
- Medium Temp Workhorse: Delivering a rated cooling capacity of 584 W at -10.00°C evaporating and 45.00°C condensing temperatures (EN12900 conditions)[cite: 1].
- High Starting Torque (HST): Equipped with a CSIR motor type and High Starting Torque, ensuring reliable start-ups even under unbalanced system pressures[cite: 1].
- Compact Form Factor: With a height of 188 mm and weighing 10.4 Kg, it maintains a highly compact footprint for tight commercial cabinet spaces[cite: 1].
Why This Compressor Matters on the Job
Aussie hospitality environments are notoriously brutal on refrigeration gear. When a kitchen hits 40°C in the middle of a summer lunch rush, with the fridge doors constantly opening and closing, the compressor underneath the prep bench cops an absolute beating. The NEK6181GK features a displacement of 7.28 cm³ and can handle a maximum condensing pressure peak of 27.71 bar, making it rugged enough for heavy-duty commercial cycles[cite: 1].
Tradie Pro Tip for R-404A:R-404A is a zeotropic blend and a synthetic greenhouse gas (HFC) subject to phase-down regulations. Always ensure you recover the existing R-404A charge into a dedicated recovery cylinder—never vent it to the atmosphere. When recharging, note that this compressor has a maximum recommended refrigerant charge of 350 g[cite: 1].

Frequently Asked Questions (FAQ)
What type of expansion device can I use with this model?
The NEK6181GK is versatile and is designed to operate with either a Capillary Tube or an Expansion Valve[cite: 1]. Ensure the device is correctly sized for R-404A pressures.
What type and amount of oil does the Embraco NEK6181GK use?
Because it is designed for HFC refrigerants like R-404A, this compressor requires ESTER (POE) oil[cite: 1]. It comes with a factory oil charge of 350 ml, and the recommended oil viscosity is ISO22[cite: 1]. POE oil is highly hygroscopic, so minimize the time the system is open to the atmosphere.
What are the pipe connection sizes?
The copper connections have the following internal diameters: the slanted suction line is 8.1 mm, the straight discharge line is 6.1 mm, and the slanted process line is also 6.1 mm[cite: 1].
