They, however, did not stop at commercial refrigeration systems only. Their built in solutions for heat pumping, gas heating, air conditioning, ventilation, temperature control and other HVAC systems and appliances, have earned them a prestige that follows their every product and component, no matter how small it is. Ranco controllers are also extremely appreciated, the most sought after being their control valves, solenoid control valves, boiler controllers, thermostat controllers, control panels and heat controller units.

Ranco is today’s most important supplier of reversing valve technology for heat pumps, also offering general use and custom-designed microprocessor-based controllers for a variety of HVAC applications. Ranco works with other manufacturers to add quality features to their products, and follows that up with superb customer service and support. Ranco’s electronic controllers and reversing valves are widely used in heating and air conditioning units in commercial building all over the world, and the company has been a leader in the commercial refrigeration market for over 50 years. Some of the other products they offers include thermostat controls, ignition controls, check valves, humidistats, and air conditioning controllers.

One of the most successful temperature control product series coming from Ranco is the manufacturer’s ETC series. The ETC is a microprocessor based Electronic Temperature Controller, which is specifically designed to offer control over heating and cooling HVAC applications. The Ranco ETC finds its use in applications such as chillers, research laboratories, aquariums, hydroponics, pools, educational applications or scientific measurement operations.

The ETC series’ Liquid Crystal Display monitor (LCD) provides a comfortable and easy to read backlit display, which shows a lot of variables and a constant readout of the temperature. Ergonomics and comfortability are at top standards, a touch keypad allowing you to easily and accurately set heating and cooling modes of operation, set point temperature and set point range. Other interesting features provided by the Ranco ETC series, include: a remote sensor that can be used of up to 400 feet away from the target, a SPDT output relay, a simple 4-step keypad programming system, the ability to change temperatures from either Fahrenheit or Celsius, a wide range of operation of up to –30 to 220 Fahrenheit degrees, a lockout switch that can prevent the tampering of the ETC by unauthorized personnel, a differential adjustment setting of 1 up to 30 F and a NEMA 1, plastic enclosure that protects it from corrosive elements and water. Its small dimensions make it ideal to use in a large number of narrow environments. The Ranco ETC’s dimensions are as follows: 7.9 x 1.8 x 1 inches (175 x 41 x 23 millimeters).

Another important segment of the Ranco Company is the pressure control manufacturing one. The Ranco SPT’s (Single Pressure Controls) are categorized under two basic types: high or low pressure. Almost all models are "make or break" on rise or fall of pressure according to which terminals are selected. In addition, all models are equipped with a manual reset option, in case you need to override automatic cycling. Ranco low pressure controls trip the manual reset system in case of a pressure drop, while thier high pressure controls trip it in case an extreme pressure rise occurs.

Other HVAC components provided by the manufacturer include air conditioning controllers, boiler controllers, check valves, defrost timers, electronic gas ignition controls, humidistats, ice equipment controls,thermostats, pressure controls and reverse valves. Whatever your heating, ventilation, air conditioning or refrigeration needs are, will be there to deliver the products that will satisfy them.
