Embraco ELF20G-A1-LDBM Scroll Compressor | 6 HP | 22,050 BTU/h (6,457 W) LBP Cooling | Three-Phase | R404A (Without 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 operates in the LBP (low back pressure) range. With 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). This version is without valves (service valves are not included; brazed/ODF connections).

6 HP Three-Phase LBP Commercial Refrigeration Scroll Compressor (R404A, Without Valves)

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 compatible with R404A/R507/R452A refrigerants. This product is supplied without service valves; if required, it can be used with a separately purchased rotalock service valve kit.

Technician Recommendations

• This product is without valves; for ease of service/maintenance you can add a rotalock service valve kit separately.
• Braze the (ODF) connections under nitrogen to prevent internal oxidation.
• 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 it for your own conditions with the Embraco selection tool.
