Product views and applications
Fire damper Ball valve
Description
The 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 Ex-areas zone 2 (gas) and zone 22 (dust).
Highest protection class (ATEX) and IP67 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 are selectable or adjustable on site. The integrated
universal power supply is self adaptable to input voltages
in the range of 24...240 VAC/DC. The actuators are 100 %
overload protected.
...Max-...-BF actuators are equipped with spring return
fail safe function, with 2 integrated auxiliary switches for
end position indication and an intrinsically safe tripping
circuit for connecting the ...Pro-TT-... safety temperature
trigger. Standard shaft connection is a double square direct
coupling with 16 × 16 mm.
Different accessories are available to adapt auxiliary
switches, terminal boxes or adaptions for ball valves and
throttle valves and other armatures.
