Copeland Comfort Control (Alco) 057539 Coil

The Copeland Comfort Control (Alco) 057539 Coil is a high-performance solenoid valve coil engineered for precise refrigerant flow regulation in commercial and industrial HVACR systems. As a genuine OEM HVAC replacement coil, this AMF-24V model is specifically designed to fit Alco solenoid valves, providing the electromagnetic force required to actuate internal plungers reliably. Operating at 24Vac (50/60 Hz) with a 12-watt power rating, it ensures consistent performance in high-duty cycle applications like chillers and heat pumps.

Built for the rigors of the field, this 18-inch lead coil features an open frame design and Class F insulation. This high-grade insulation is critical for protecting the internal windings against the thermal stress and vibration common in mechanical rooms. This coil serves as a direct drop-in for technicians addressing solenoid coil burnout or failed actuation, ensuring your refrigeration solenoid valve returns to optimal MOPD (Maximum Operating Pressure Differential) specifications without the need for additional modifications.

• OEM Compatibility: Precision-matched for Copeland Comfort Control and Alco valve bodies to prevent mechanical jamming.
• Enhanced Durability: Class F insulation provides superior resistance to heat and electrical fluctuations, reducing the risk of premature shorting.
• Easy Installation: Pre-stripped 18" leads and an open frame design allow for fast integration into existing control circuits.
• Broad Application: Suitable for a wide range of refrigerant and industrial solenoid valves used in air handling and humidity control.
• Reliable Operation: Optimized 12-watt draw ensures a strong magnetic field for positive valve opening and closing.

What causes a solenoid coil like the 057539 to burn out?
Coil failure is often caused by incorrect voltage, severe power fluctuations, or a stuck plunger. If the plunger cannot seat properly due to debris, the resulting "inrush current" can overheat the Class F insulation and cause a short circuit.

Can this 24V coil be used on DC systems?
No, this specific model is rated for 24Vac. For DC applications, you must use the Magmax (MM) series to avoid electrical damage and ensure proper magnetic actuation.

Does this coil include the enclosure or housing?
The 057539 is an open frame coil. If your application requires weather protection, you may need to pair it with an ASC2 style housing or a compatible conduit junction box.
