Copeland Comfort Control (Alco) 097456 / FD113-ZUK Oil Pressure Safety Control – 24–240V, 4–65 PSI, 20–150 Second Adjustable Delay

The Copeland Comfort Control (Alco) 097456 Oil Pressure Safety Control—also known as FD113-ZUK—is a high-precision, OEM-quality safety device designed to protect pressure-lubricated compressors from damage caused by low oil pressure. Engineered for versatility and reliability, this control operates on 24–240 Vac/Vdc, features an adjustable pressure range of 4–65 PSI, and includes a 20–150 second adjustable electronic time delay to prevent nuisance shutdowns.

Equipped with two 36-inch capillary tubes and 1/4" flare nut connections, the FD113-ZUK ensures easy installation and secure fitment. The SPDT manual reset switch allows for safe compressor restart after shutdown, while its adjustable differential pressure switch and timer provide maximum application flexibility.

How It Works:
The FD113 senses effective oil pressure in pressure-lubricated compressors. If oil pressure falls below the set threshold, the timer activates. If pressure fails to recover within the selected delay time, the control shuts down the compressor to prevent damage. This safeguard helps ensure optimal system performance and prolongs compressor life.

Applications:

• HVAC and refrigeration compressor protection

• Commercial and industrial cooling systems

• OEM and direct replacement for Copeland, Alco, and compatible units

Ensure reliable compressor operation and protect against costly repairs with the Copeland Comfort Control (Alco) 097456 / FD113-ZUK Oil Pressure Safety Control—engineered for precision, durability, and peace of mind.
