Designed with new and existing and systems in mind, the AK-RC 251 Optyma™ Control electronic controller eliminates the need for mechanical thermostats in cooling applications along with defrost timers in freezer applications.


The Danfoss AK-RC 251 Optyma™ Control can control compressors, solenoids, fans, lights, crankcase heaters, and up to two defrosts. The Optyma™ Control features a weatherproof enclosure and is compatible with standard 3⁄4 inch fittings. Easy to wire and quick to mount, this temperature controller can reduce installation time by up to 60% and improve room efficiency by up to 30%. For extra convenience, the control comes kitted with two NTC sensors: one five foot sensor and one ten foot sensor.

"The Optyma™ Control is a must-have for any cooling system," says Chris Nitz, Manager, Segment Marketing, ACR - NAM. "This all-in-one temperature controller not only makes installation a snap and controlling all your peripherals a breeze, but improves efficiency, too."

When you use the Optyma™ Control for your new and upgraded walk-in freezer and cooler installations, you will find yourself with additional time to focus on what really matters.
