This OEM-branded control is designed for industrial refrigeration systems requiring precise defrost cycle management.

Frequently Asked Questions

What is the RANCO F25-107 defrost termination control used for?

The RANCO F25-107 is used in industrial refrigeration systems to manage defrost cycles. It terminates defrost when the evaporator coil reaches a set temperature (40°F to 75°F) and delays fan restart until the coil cools, preventing warm air circulation. This SPDT control with a 60-inch capillary is common in walk-in coolers and freezers.

What are the specifications of the RANCO F25-107 fan control?

The RANCO F25-107 is a defrost termination and fan delay control with an adjustable range of 40°F to 75°F. It has a fixed 20°F constant differential, SPDT contact form, and a 60-inch capillary length. The OEM brand is RANCO, and the manufacturer part number is F25-107.

Where to buy the RANCO F25-107 in worldwide?

You can source the RANCO F25-107 through 3G Electric, a global industrial equipment distributor established in 1990. We handle full logistics, customs clearance, and delivery to worldwide locations. Contact us for availability and lead time; we supply OEM-branded controls for industrial refrigeration systems.

How to install the RANCO F25-107 defrost termination control?

Install the RANCO F25-107 by mounting the control bulb on the evaporator coil using the 60-inch capillary. Wire the SPDT contacts according to the refrigeration system schematic, ensuring the defrost termination setting (40°F to 75°F) matches system requirements. Always follow generic best practices for refrigeration controls and consult a qualified technician.
