Overview
The RGE-X3R4-7 is a three-phase capillary-type condenser fan speed controller designed for industrial refrigeration condensing units, compatible with 380 to 415V three-phase power supply, rated current 5A and supporting 50/60Hz dual frequency. It relies on copper capillary tubes to real-time sense system condensing pressure and automatically adjust the operating speed of three-phase cooling fans, which effectively stabilizes system pressure fluctuations caused by ambient temperature changes, cuts energy consumption and reduces compressor load. Equipped with a large metal heat dissipation mounting base and integrated fixing brackets, the sealed plastic housing provides reliable dust and moisture resistance. Adopting pure mechanical pressure adjustment structure, this unit features stable operation, low failure rate and convenient on-site calibration and maintenance, suitable for heavy-duty refrigeration and HVAC cooling systems.
