ASCO 099257-004-D Coil

The ASCO 099257-004-D Coil is a heavy-duty 24Vac 60Hz solenoid replacement coil designed for industrial and commercial HVACR applications. Engineered with a 15.4 Watt power rating, this Class FT coil features high-grade epoxy encapsulation to withstand moisture and thermal cycling in demanding environments. It is specifically built for compatibility with ASCO RedHat solenoid valves, providing reliable electromagnetic force to ensure precise valve actuation and long-term cycling performance. When troubleshooting persistent chatter or coil burnout, technicians often turn to the 099257-004-D to restore system integrity. This coil meets NEMA 4X standards for protection against corrosion and water ingress, making it a staple for refrigeration control systems and fluid management. Ensure your voltage and frequency align with the 60Hz specifications to prevent inductive overheating and premature insulation failure during continuous duty cycles.

Key Benefits

• High Thermal Stability: The Class FT insulation provides superior heat dissipation for high-ambient mechanical rooms.
• Precise Actuation: Matches 24V AC operational requirements for accurate plunger lift and seating.
• Durable Construction: Epoxy-molded design protects internal windings from vibration and environmental contaminants.
• OEM Compatibility: Drop-in replacement for ASCO RedHat series valves, ensuring correct fitment and pressure ratings.

Common Questions

What causes a 24V solenoid coil to buzz or chatter?
Buzzing usually indicates a lack of proper voltage, a misaligned plunger, or debris in the valve body. Verify that your transformer is providing a consistent 24Vac 60Hz signal under load.

Can I use a 60Hz coil on a 50Hz system?
No. Using a 60Hz solenoid coil on a 50Hz supply will result in higher current draw, leading to overheating and winding failure. Always match the nameplate frequency.

How do I verify the insulation class for my application?
This Class FT coil is rated for specific temperature rises. Technicians should confirm the ambient temperature and media temperature do not exceed the insulation's thermal limits.
