Ranco Thermostats & Accessories: Decades of Temperature Control Expertise
Ranco has earned a reputation as one of the most trusted names in temperature control technology, with thermostats and accessories that span electromechanical and fully electronic designs. Having been in the controls business for nearly 90 years, Ranco stands today as a leading producer of both electronic and electromechanical controls. That depth of experience is evident in every thermostat and accessory they produce — from basic capillary-tube units to sophisticated multi-stage digital controllers.
The ETC Series: Electronic Precision for Modern Systems
At the heart of Ranco's thermostat lineup is the widely respected ETC Series. The Ranco ETC Series Electronic Temperature Control offers a full-featured electronic replacement for electrical-mechanical temperature controls used in many commercial refrigeration applications. What sets the ETC Series apart is its engineering flexibility: 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, with models available in 120/208/240V AC and 24V AC.
Practically speaking, this means a single ETC Series control can serve a broad range of equipment. Key features include an anti-short cycle compressor delay for cooling applications, a wide temperature range of -30°F to 220°F, LCD read-out for sensor temperature, control settings and relay status, EEPROM memory that retains control settings during power outages, and a keypad lockout to prevent end-user alteration of settings.
Line Voltage & Capillary Thermostats
Beyond the ETC Series, Ranco offers a robust selection of line voltage and capillary-style thermostats suited to commercial refrigeration, HVAC, beverage cooling, and ice-making applications. Ranco line voltage thermostats provide on/off control for air conditioning, refrigeration, and commercial heating; they feature two programmable stages for cooling and heating and an LCD screen for indicating relay status and temperature readings, and are capable of sensing temperatures ranging from -30 to 220 degrees F.
For ice machine applications specifically, Ranco produces dedicated thermostat kits — such as the A-Series ice machine thermostat kits — complete with cold cutout, bulb holder, and capillary tubing, making them a go-to solution for commercial ice equipment maintenance and repair.
Thermostat Accessories: Sensors & Supporting Components
A thermostat is only as accurate as its sensing components. Ranco thermostat accessories include temperature sensors that can measure temperatures ranging between -30 and 220 degrees F, supplied with an IP67 rated thermistor sensor and 22-gauge cable. This IP67 rating means the sensor probe is protected against dust and water immersion — an important consideration in humid refrigeration and marine environments. Ranco also offers temperature controls, pressure switches, defrost timers, fan cycle controls, and temperature sensors for precise refrigeration and HVAC management.
Cross-Compatibility and Industry Trust
One practical advantage Ranco thermostats offer is broad cross-reference compatibility. Ranco product model numbers generally cross-reference to the equivalent Honeywell, Johnson Controls, White-Rodgers, and Robertshaw manufacturer part numbers. This means technicians and DIYers alike can often find a Ranco thermostat as a drop-in replacement for units from other major brands — a significant benefit when sourcing parts for older or hard-to-service equipment.
Whether you are maintaining commercial refrigeration systems, servicing HVAC units, or repairing ice machines, Ranco's lineup of thermostats and accessories delivers the accuracy, durability, and application flexibility that demanding environments require.
