"This Actuator is extremely versatile!"
We are curently using this model Honeywell Actuator on isolation dampers on both the inlet and outlet sides of a direct expansion coil on a Custom Conditioned Air Supply System that we manufacture for the automotive industry. The temperature range that this actuator see's is the entire range that it is rated at (-40°F to +140°F) with absolutely no issues or problems. We decided to try this Honeywell Actuator for the temperature range, as well as the high torque rating. Sometimes ice builds up on our damper baldes and we need the extra torque in order to open or close a damper that has ice on it. Great Product and we continually purchase this actuator.
