Ranco A30-1769 Temperature Control

The Ranco A30-1769 is a heavy-duty constant differential temperature control engineered for critical performance in commercial refrigeration and ice machine applications. For technicians managing walk-in coolers or localized cooling loops, this dual-voltage 120/240V switch provides a reliable SPST contact configuration designed to handle high-amperage compressor loads without premature pitting. The unit includes a 36-inch capillary tube, allowing for flexible positioning of the sensing element to capture accurate evaporator or ambient temperatures.

Operating with a fixed 7-degree F differential, the A30-1769 prevents rapid short-cycling, protecting the system from unnecessary mechanical wear and thermal stress. The laser-welded stainless steel bellows ensure pneumatic integrity, while the intuitive dial interface allows for precise setpoint adjustments. Whether you are performing a field replacement for a Traulsen 12769 or a Hobart 2906, this original equipment part maintains the specific temperature range requirements necessary for demanding HVACR environments.

• Fixed 7°F Differential: Optimizes compressor run times and prevents rapid cycling in refrigeration circuits.
• 36" Capillary Lead: Provides sufficient reach for efficient sensor mounting in tight evaporator housings.
• Direct OEM Cross-Reference: Serves as a primary replacement for Traulsen, Hobart, and Robertshaw A30 series cold controls.
• Rugged Build Quality: Features stainless steel bellows and high-amperage contacts for long-term electrical reliability.

Can the A30-1769 be used on both 120V and 240V systems?
Yes, this mechanical temperature switch is rated for dual voltage, making it a versatile stock item for various commercial service calls.

What is the primary application for this specific Ranco model?
While used in diverse refrigeration setups, it is a standard component for ice machine temperature control and walk-in cooler regulation where a constant differential is required.

How do I handle the capillary tube during installation?
Always avoid sharp kinks or pinching. Ben the 36-inch capillary gradually to ensure the vapor charge within the tube can accurately transmit pressure to the bellows.
