The Model R series thermostat represented a remarkable engineering achievement in 6 or 7 years. A compact design, totally enclosed control, crafted in, then, modern two tone, Bakelite, dielectric material. One third of the size and weight of the Kelvinator E, it was a user friendly, fully adjustable thermostat.
The thermostat also marks the early entrance of the Ranco name into the refrigeration and air conditioning temperature control business, supporting the major equipment manufacturers of the period. The Ranco name would survive for many years as a leader in the HVACR control field.
