Embraco ERF30G-A1-NBBM Scroll Compressor | 4 HP | 25,877 BTU/h (7,577 W) MBP Cooling | Three-Phase | R404A (Without Valves)

The Embraco ERF30G-A1-NBBM scroll compressor is designed for medium temperature (MBP) commercial refrigeration applications — cold rooms, supermarket aisles, beverage coolers and medium temperature display cabinets. With a nominal power of 4 HP, it runs on a three-phase (380-420V / 3~ / 50Hz) supply in the MBP (medium back pressure) range. With R404A refrigerant it delivers a cooling capacity of 25,877 BTU/h (7,577 W) at AHRI MBP (-6.7°C / +48.9°C) conditions; this version has no valves (service valves are not included; solder/ODF connections).

Technician Tips

• Braze the solder (ODF) connections under nitrogen to prevent internal oxidation.
• Verify the phase sequence and direction of rotation of the three-phase motor at first start-up; a scroll compressor must not run in reverse.
• Evacuate the system thoroughly before commissioning; moisture leads to oil breakdown and winding failure.
• The stated capacity is at AHRI MBP (-6.7°C / +48.9°C) conditions; confirm it for your own conditions with the Embraco selection tool.
