Ranco O18-100 Control

The Ranco O18-100 Ice Bank Control is a critical component for commercial refrigeration systems and ice makers requiring precise ice thickness management. Designed with a 76-inch capillary tube, this temperature-sensitive control allows for remote bulb placement far from the electrical enclosure, providing flexibility in crowded evaporator assemblies. The O18-100 utilizes a SPDT switch configuration, allowing for either normally open or normally closed operation to cycle the compressor or solenoid based on ice bank formation. This mechanical ice bank controller operates by sensing the change in temperature as ice builds up on the bulb, ensuring the ice thickness remains consistent for specialized cooling applications. Built for the rigors of field service, this controller features a high-impact plastic cover and an accessible differential adjustment screw to fine-tune the cut-out and cut-in points. It is a direct fit for various beverage dispensers and specialized HVACR equipment requiring reliable ice builder controls.

• Extended 76-Inch Capillary: Provides the necessary reach for complex evaporator coils and remote reservoir mounting.
• SPDT Switching: Offers versatile wiring options for both cooling and alarm circuits depending on the HVACR system requirements.
• Heavy-Duty Construction: Built to withstand the high-moisture environments common in commercial ice machines and soda fountains.
• Precise Calibration: Features an adjustable range to maintain exact ice thickness, preventing evaporator freeze-ups or short-cycling.

What is the primary function of the Ranco O18-100?
The O18-100 is designed to maintain a specific thickness of ice around the sensing bulb in an ice bank or thermal storage system by cycling the refrigeration system on and off.

Can this be used for both high-voltage and low-voltage applications?
Yes, the SPDT switch is rated for standard pilot duty and motor loads, typically up to 240V AC, making it compatible with most commercial refrigeration control circuits.

How do I adjust the ice thickness setting?
The control features a range adjustment screw; turning it modifies the temperature point at which the switch triggers, effectively increasing or decreasing the physical ice build-up on the bulb.
