Temperature Controls

The Ranco® A12 and 9531 Series Constant Cut-in Temperature Controls are designed to switch electrical components of refrigeration systems in response to sensed temperatures.

The Ranco® A22, A30 and 9530 Series Constant Differential Temperature Controls are designed to switch electrical components of refrigeration systems in response to sensed temperatures.

The Ranco® DCV Series of flow controllers for refrigeration is specially designed to allow the control of the temperature in refrigerators by opening and closing a flow passage for the cooled air from the equipment's cooler environment, normally the freezer.

The Ranco Digital Controller Series offers versatile solutions for temperature and humidity management. This series is supported by various temperature sensors, serial converters, and mounting plates for complete system integration and control.

The Paragon ® ERC-2 Electronic Refrigeration Control is a microprocessor-based electronic controller designed to manage both the temperature and the defrost functions of a commercial refrigeration unit.

The Ranco® ETC Series Electronic Temperature Control offers a full-featured electronic replacement for electrical-mechanical temperature controls used in many commercial refrigeration applications. With its wide temperature range, one and two stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is designed to provide application flexibility. Models available include 120/208/240V AC and 24V AC.

These controls are designed to shut down a piece of equipment if the operating conditions begin to approach freezing (as water freezes it expands and will rupture the chiller barrel tubes). The 016-264 has a manual reset feature, necessitating human intervention in the event of a shutdown. Type P32 Low Pressure Limit Control. The Ranco® P32 low pressure control provides freeze protection for low refrigerant protection on chillers and other refrigeration systems by sensing suction pressure. It is suitable for R12, R22 and R502 refrigerants. A time delay is provided to allow for startup in low ambient and momentary low pressure conditions during the run period. The timer is of the heated bimetal (warp) switch design with an ambient temperature compensator. Once the time delay period (standard is 120 seconds) has elapsed, the manual reset button must be depressed to restart the compressor. A five minute cool-down period is required before resetting.

The Ranco® K Controls are used all over the globe to control the temperature in commercial and domestic refrigeration, air conditioning and heating applications. Typical uses include refrigerators, freezers, bottle and liquid coolers, and refrigerator display cases.

The Ranco® Wide Range O Series Temperature Controls provide a wide selection of controls customized to allow users exact adjustments within manufacturers' limits. The Ranco O Series features heavy-duty plated steel frames, non-conductive covers with front-located captive cover screws, raised screw terminals for fully accessible wiring, and large easy-to-read scales. Recognizing the need for flexibility in design of refrigeration equipment, these controls offer a wide selection for such products as self-contained refrigerators, freezers, coolers, walk-in units, and refrigeration display cases.

The Ranco® R Series Cold Controls are used to control the temperature in commercial and residential refrigeration, air conditioning and heating applications. Typical uses include refrigerators, freezers, bottle and liquid coolers, and refrigerator display cases.

The thermostats line for refrigeration, which includes the RC, TSV and TXV Series, are designed especially for controlling temperature in refrigerators, freezers, air conditioners, water coolers and other applications requiring operation cutoff by temperature. The RC models are traditional and offer ease of use and versatility, with a wide range of models. The TSV line incorporates a low-noise electrical switch, and the TXV line includes explosion-proof models.

The Robertshaw® RTC-500 is a digital controller that has two output sockets to control temperature (work1) and humidity (work2). The RTC-500 controller comes with two probes, a dual temperature and humidity sensor and a fully submersible temperature sensor. The large, backlit LCD screen displays temperature, humidity, and other parameters. The three-button design allows for quick programming of parameter settings, including alarm limit calibration, protection time, unit switching, and more.

The Robertshaw® RTC-500-WIFI is a digital controller that has two output sockets to control temperature (work1) and humidity (work2). The RTC-500-WIFI offers Wi-Fi for remote connectivity through the free mobile app. The RTC-500-WIFI controller comes with two probes, a dual temperature and humidity sensor and a fully submersible temperature sensor. The large, backlit LCD screen displays temperature, humidity, and other parameters. The three-button design allows for quick programming of parameter settings, including alarm limit calibration, protection time, unit switching, and more. Applications include: Brewing, Incubation/Breeding, Greenhouses, Terrariums, Aquariums, Reptile Habitats and more
