Application
Description size M
The ExMax actuators are a revolution for safety, control and shut-off
dampers, 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 IP 66 protection, small dimensions,
only 9,5 kg weight, universal functions and technical data, an integrated
heater 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 240 VAC/DC.
The actuators are 100% overload protected.
ExMax-...-F actuators are equipped with spring return fail safe function
Standard shaft connection is a double squared direct coupling with
16 × 16 mm.
Different accessories are available to adapt aux. switches, terminal boxes
or adaptations for ball valves and throttle valves.
