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 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 and torques 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-...F actuators are equipped with spring return fail safe function.
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.
