Refrigeration Controls

Ranco refrigerator cold controls regulate the temperatures of freezers, water coolers and air conditioners in commercial refrigeration applications. They feature a close on rise switch to handle temperature fluctuations and have SPST (single pole single throw) switch actions to adjust temperature settings. Choose from a wide range of these cold controls, available in temperatures ranging from -12 to 55 degrees F.

Ranco O Series temperature controls are ideal for heating, air conditioning, ventilating and commercial refrigeration systems. They include heavy-duty, non-corrosive, plated steel frames & raised screw terminals for fully accessible wiring. They feature non-conductive covers with front-located captive cover screws and large easy-to-read scales. The sensing elements comprise refrigerant charges that develop pressures relative to the temperature being sensed and operate the switch located within. These universally mounted, compact design controls meet NEMA 1-rated enclosures to prevent accidental contacts & dust from entering in and have laser-welded bellows for extended life. They further feature SPST (single pole single throw) or SPDT (single pole double throw) switches to adjust temperature settings and are available in extra low, medium, high and low temperature types.
