Refrigeration Controls

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.

Ranco refrigeration controls are used to replace malfunctioning parts in compatible equipment to ensure proper holding temperatures. They include break-off shafts, dial knobs & mounting brackets for easy & fast installation and switch electrical components of refrigeration systems in response to sensed temperatures. These controls have SPST (single pole single throw) on / off switches to break or make the connections between two terminals and enable adjusting or fixing temperature settings. They provide high amperage contacts and also offer laser welded, stainless steel bellows for volume compensators, as well as to withstand high pressures & temperatures. They have quick-connect terminals with screws for ease-of-installation and are available in controlling temperatures ranging from 3 to 42 degrees F.

Ranco A Series fan control cycles replace OEM controls that govern the on / off compressor functions. They include break-off shafts, dial knobs & mounting brackets for quick & easy installation and feature SPST (single pole single throw) or SPDT (single pole double throw) switches to adjust temperature settings. These kits fearure close on rise switch action that engage the closed electrical circuits when the temperature increases & automatically reset open when it falls, to provide maximum application flexibility. Choose from a wide range of these kits, available in temperatures ranging from 45 to 90 degrees F.

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.
