ARIS offers special drive variants for applications in potentially explosive areas of zone 2 or 22. ARIS Actuators of the series Nano+ (classic actuators up to 120 Nm) and Tensor (fully electronically controlled precision drives) are approved for use in Zone 2 or 22 in a modified version approved by a notified body. All actuators for this range are subject to additional tests and perform a special leak test. The advantages lie in the unchanged dimensions and an unchanged adjustment to the standard drive. As these applications are usually carried out with pressure-tight encapsulated actuators, the variant for zone 2 or 22 offers a clear price advantage.
