Emerson Alco 065677 Coil

The Emerson Alco 065677 is a heavy-duty Model RMF solenoid coil designed for mission-critical refrigeration and air conditioning applications. Engineered to interface with Emerson solenoid valves, this 24Vac coil features a 50/60 Hz dual-frequency rating, ensuring consistent performance across varying power supply parameters. With a 7-watt power consumption, it provides the electromagnetic force necessary for reliable refrigerant flow control while maintaining thermal efficiency through its Class F insulation rating, which is rated for temperatures up to 155°C (311°F).

Built for the rigors of field service, this 7 watt solenoid coil utilizes an open frame design to facilitate rapid heat dissipation during continuous duty cycles. The unit comes equipped with 18-inch leads, providing ample length for secure terminal connections in complex control cabinets. As a standard HVACR replacement coil, the 065677 is frequently utilized in commercial systems where vibration resistance and compact form factors are essential for long-term system stability. Technicians should verify the MOPD (Maximum Operating Pressure Differential) when retrofitting, as this coil is optimized for narrow-profile valve bodies requiring a high-integrity refrigeration solenoid part.

Key Benefits

• Broad Compatibility: Ideally suited for Emerson Alco solenoid valves in commercial refrigeration and HVAC systems.
• Superior Insulation: Class F insulation provides high-temperature resistance, preventing premature burnout during high-ambient operation.
• Installation Versatility: Features 18-inch open frame leads, allowing for flexible wiring configurations and ease of access.
• Dual-Frequency Support: Operates seamlessly on both 50Hz and 60Hz 24V systems without core chatter or efficiency loss.
• Compact Footprint: The Model RMF design ensures a precise fit in tight valve assemblies common in modern reach-in and walk-in units.

Common Questions

Can I use this 24V coil to replace a 120V model?
No. Solenoid coils must match the system control voltage exactly. Replacing a higher voltage coil with this 24Vac coil without a transformer adjustment will lead to immediate component failure.

Is the RMF model interchangeable with ASC2 series coils?
The RMF is often used as a wholesale replacement part, but internal dimensions and mounting hardware vary. Always confirm the valve stem diameter and height before switching between Emerson solenoid coil series.

What is the impact of using this on a 50Hz system versus 60Hz?
This coil is rated for both; however, operating on 60Hz may slightly decrease the maximum pressure the valve can open against compared to 50Hz operation. Verify system pressures against the valve’s MOPD rating.
