The new RedMax actuators are a revolution for safety, fire 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 66 protection, small dimensions,
only 3,5 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. 5 motor running times and 2 torques as
well as 2 spring return times - according to the actuator type - are
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-...-BF
actuators are equipped with spring return fail safe function,
with integrated aux. switches for end position indication and an intrinsic
safe circuit to connect an external passive potential free thermostat.
Standard shaft connection is a double squared direct coupling with
12 x 12 mm.
Different accessories are available to adapt aux. switches, terminal
boxes or adaptations for ball valves and throttle valves.
