The ExMax 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 1, 2 (gas) and zone 21, 22 (dust).
Highest protection class (ATEX) and IP67 protection, small dimensions,
only 9,5 kg weight, universal functions 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-...-F3 actuators are equipped with spring return fail safe function.
Additionally the ...Max-...-SF3 and ...-BF3 actuators are equipped with
2 integrated, potential free auxiliary switches each and ...Max-...-BF3
comes with 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.
