Emerson Alco 055129 Coil

The Emerson Alco 055129 is a heavy-duty DMG series solenoid coil designed for high-performance fluid control in commercial HVACR systems. Operating at 24Vac (50/60 Hz) with a 10-watt power draw, this Class F insulated coil is built to withstand high thermal loads and frequent cycling without insulation breakdown. As a direct replacement for various Alco and Emerson solenoid valves, it features a rugged NEMA 1 junction box and 6-inch lead wires for straightforward field wiring. This 24V replacement coil provides the necessary electromagnetic force to actuate valve plungers accurately, ensuring reliable refrigerant flow control in both liquid and suction line applications. Whether you are performing a solenoid coil replacement or a new installation, verifying compatibility with the valve body series is essential for maintaining system pressure integrity and optimal MOPD performance.

• Dual Frequency Compatibility: Rated for 50/60 Hz, offering flexibility across different power supply configurations.
• Enhanced Thermal Resistance: Class F insulation allows for higher operating temperatures, reducing the risk of solenoid coil burnout during continuous operation.
• Field-Ready Construction: Integrated junction box facilitates secure electrical connections and protects leads from mechanical stress.
• Optimized Wattage: The 10W rating provides the high-torque actuation required for larger valve bodies while minimizing energy consumption.

What causes a solenoid coil to fail prematurely?
Premature failure is often caused by incorrect voltage supply, over-tightening the coil nut, or mechanical debris preventing the plunger from seating, which leads to excessive amperage draw and overheating.

Can the DMG coil be used on liquid and gas lines?
Yes, provided the coil is matched to the specific Emerson solenoid valve body and the system pressures do not exceed the valve's Maximum Operating Pressure Differential (MOPD).

Does this coil include the housing?
Yes, the 055129 model includes the protective metal junction box and standard 6-inch electrical leads for integration into conduit systems.
