Ranco A30-3618 Refrigeration Control

The Ranco A30-3618 Refrigeration Control is a versatile SPST constant differential cold control engineered for precision temperature management in commercial refrigeration systems. Designed as a direct replacement for various Beverage-Air 502-014A applications, this unit features a 30-inch capillary tube and a 17°F fixed differential to prevent excessive compressor cycling. The laser-welded stainless steel bellows ensure responsive pneumatic action, providing a normal "off" at 23°F and a normal "on" at 40°F, with a "warm on" limit of 45°F. This industrial temperature controller is built with high-amperage contacts capable of handling 20 Amps at 240V AC, making it a reliable choice for walk-in coolers, ice machines, and beverage dispensers. The inclusion of a dial adjustment and 1/4-inch quick-connect terminals facilitates straightforward integration for technicians servicing HVACR refrigeration units. Its compact frame is optimized for durability in harsh environments, maintaining stable setpoints for critical cooling inventory.

• Universal Compatibility: Specifically matches Beverage-Air OEM specs and adapts to most commercial refrigerators and freezers.
• System Efficiency: The 17°F differential minimizes short-cycling, extending the lifespan of the compressor and electrical components.
• Simplified Installation: Comes with a 30-inch vapor-filled capillary and standard quick-connects for rapid field replacement.
• Rugged Construction: Features high-amperage contacts and stainless steel bellows for heavy-duty commercial service.

• What is the temperature range for the Ranco A30-3618? This control operates with a normal off-cycle at 23°F and a normal on-cycle at 40°F, providing a consistent 17°F differential for medium-temp applications.
• Can I use this for an ice machine? Yes, the A30-3618 is frequently utilized in ice machine and beverage cooler applications where a constant differential is required.
• Is the capillary length sufficient for remote mounting? The 30-inch capillary provides enough reach for most standard cabinet or evaporator coil placements.
