Blanket-free spring-return electric actuator

Jon Lawson

Electric actuators in high-temperature applications on ventilation dampers traditionally rely on insulation blankets to perform reliably. The RCS Sure 65 electric actuator is now available with a new, simpler, and cost-efficient “blanket-free” design that eliminates the need for thermal insulation blankets in SurePowr™ actuators. It still allows for compliance with NFPA 130 and NFPA 502 standards, and is capable of operation after exposure to a temperature of 250 degrees C (482 degrees F) for two hours.

The Sure 65 is the first of three SurePowr™ actuators – Sure 65, 100 and 150 – to be introduced. It will eliminate the need for expensive accessories, offer reductions in price and physical size, improve access to the actuator internals, and create an improvement for tunnel ventilation systems.

Dave Evans, CEO of Dresser Natural Gas Solutions - RCS said, “The RCS SurePowr™ product offering has long been the go-to product for rugged and reliable damper actuation in transit tunnel ventilation and smoke control applications. Our American made line of Spring-Return actuators continue to provide innovative and reliable service in this challenging environment, and this latest improvement shows our commitment to constantly improving our product offerings to the many markets we have served for over 50 years.”
