Ranco A30-2282 Refrigeration Control

The Ranco A30-2282 is a professional-grade constant differential refrigeration control engineered for precise temperature management in commercial refrigerators, freezers, and ice machines. This SPST cold control features a factory-set 43°F cut-out and 48°F cut-in, maintaining a steady 5-degree differential to prevent short-cycling and ensure compressor longevity. Built with laser-welded stainless steel bellows, the unit provides reliable pneumatic action through its 48-inch capillary tube, allowing for versatile sensor placement within the evaporator or cabinet environment. This mechanical thermostat is a direct OEM replacement for Traulsen 36989-00 and is compatible with various Taylor Freezer and Uni-Line configurations. Designed for heavy-duty HVACR refrigeration service, it includes a break-off shaft for fast terminal integration and utilizes standard 1/4-inch quick-connect terminals for a secure electrical interface.

• Constant Differential Performance: Maintains a fixed 5°F spread between cut-in and cut-out to optimize system efficiency.
• Durable Construction: Features laser-welded bellows for high-cycle reliability in demanding commercial environments.
• Flexible Installation: The 48" capillary sensing element provides ample reach for accurate probe positioning.
• Broad Compatibility: Serves as a direct cross-reference for major brands like Traulsen and Robertshaw.
• High-Amperage Contacts: Rated for robust switching capabilities in single-pole, single-throw applications.

What is the primary application for the Ranco A30-2282?
This control is primarily used in reach-in coolers, ice machines, and beverage dispensers that require a constant differential to regulate temperature between 43°F and 48°F.

Is the temperature range adjustable?
While the differential is fixed, the range can typically be adjusted via the slotted shaft to fine-tune the cut-in and cut-out setpoints for specific cooling requirements.

Can this replace a control with a shorter capillary?
Yes, the 48-inch capillary can replace shorter leads; however, ensure the excess tubing is coiled away from vibration and not kinked to maintain pneumatic sensing accuracy.
