Embraco ELF20G-A1-LDBM Scroll Compressor | 6 HP | 22,050 BTU/h (6,457 W) LBP Cooling | Three-Phase | R404A (With Service Valves)

Designed for low temperature (LBP) commercial refrigeration applications — cold rooms, blast freezers and low temperature display cabinets — the Embraco ELF20G-A1-LDBM is a scroll compressor. With a nominal power of 6 HP, it has a three-phase (380-420V / 3~ / 50Hz) supply and runs on R404A refrigerant. At ARI LBP conditions (evaporating -31.7°C / condensing 40.6°C) it delivers a cooling capacity of 22,050 BTU/h (6,457 W); it is supplied with service valves.

6 HP Three-Phase LBP Commercial Refrigeration Scroll Compressor (R404A)

Embraco (Nidec Global Appliance) scroll compressors provide reliable, durable performance in low temperature commercial refrigeration with few moving parts, low vibration and high efficiency. The ELF20G-A1-LDBM is a three-phase solution with service valves, compatible with R404A/R507/R452A refrigerants.

Technician Recommendations

• Braze the connections on the service (rotalock) valves under nitrogen to prevent internal oxidation.
• In LBP applications, pay attention to selecting the correct refrigerant (R404A/R507/R452A) and a suitable expansion device.
• On the three-phase motor, verify the phase sequence and direction of rotation 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 ARI LBP (-31.7°C / 40.6°C) conditions; confirm the actual capacity for your own evaporating/condensing temperatures with the Embraco selection tool.
