The Ranco A22-1112 Refrigeration Control is a heavy-duty, field-adaptable constant differential temperature control engineered for high-demand commercial refrigeration. As a primary refrigeration thermostat replacement, this SPST cold control utilizes laser-welded stainless steel bellows and high-amperage contacts to manage compressor cycles in reach-in coolers, beverage dispensers, and ice machines. This specific unit features a 72-inch capillary tube for flexible remote sensing and is electrically identical to the Ranco A22-1112-070, ensuring a direct fit for existing service inventory. Designed for vapor-filled capillary pneumatic action, it operates with a fixed 5°F differential, maintaining precise setpoints across its 25°F to 44°F range. This control does not include an "Off" position, making it ideal for systems requiring continuous operation or external power cycling. The package includes break-off adjustment shafts, allowing technicians to customize the dial fit for various cabinet depths during field installation. Key Benefits Universal Compatibility: Specifically designed as an adaptable replacement for standard commercial cold controls in vending and food service equipment. Enhanced Durability: Features laser-welded bellows that withstand high-pressure environments better than traditional soldered components. Simplified Installation: Comes with standard 1/4-inch quick-connect terminals and adjustable hardware for fast service calls. Reliable Switching: The SPST switch action handles inductive loads up to 20 Amps at 240V AC, providing robust performance for larger compressor motors. Common Questions Is the Ranco A22-1112 a direct replacement for the A22-1112-070? Yes, the A22-1112 and A22-1112-070 share identical electrical specifications and temperature ranges, making them fully interchangeable in professional HVACR applications. Can the differential be adjusted on this model? No, this unit is a constant differential control with a fixed 5°F swing. For applications requiring a variable differential, you may need to consult the Ranco A30 series. Does this control have a manual "Off" setting on the dial? The A22-1112 is a "No Off" model. It will continue to cycle based on sensed temperature unless power is disconnected from the circuit.
