Description size M
The new RedMax actuators are a revolution for safety, control and shut-
off dampers, VAV systems, ball valves, throttle valves and other motorized
applications for HVAC systems, in chemical, pharmaceutical, industrial
and Offshore-/Onshore plants, for use in EEx-areas zone 2 (gas) and
zone 22 (dust).
Highest protection class (ATEX) and IP 65 protection, small dimensions,
only 9,5 kg weight, universal functions and technical data, an integrated
heater and an optional stainless steel housing guarantee safe operation
even under difficult environmental conditions. High quality brushless
motors guarantee long life.
All actuators are programmable and adjustable on site. Special tools
or equipment are not required. Motor running times and torques -
according to the actuator type - selectable or adjustable on site. The
integrated universal power supply is self adaptable to input voltages
in the range of 24 to 230 VAC / DC.
The actuators are 100% overload protected and self locking.
RedMax-...-F actuators are equipped with spring return fail safe function
Standard shaft connection is a double squared direct coupling with
16 x 16 mm.
Different accessories are available to adapt aux. switches, terminal
boxes or adaptations for ball valves and throttle valves.
