Industry-Leading Safety in the World’s Most Demanding Environments
Schischek actuators specialize in explosion-proof electric operation for flammable gas and dust environments [3].
These units operate through sophisticated intrinsically safe electrical circuits that limit current, voltage, and power to prevent ignition sources [5]. Primary applications include offshore platforms, chemical plants, oil refineries, and industrial HVAC systems.
Schischek actuators maintain comprehensive certifications including ATEX, IECEx, UL, CSA, and ExGostR compliance [6]. The aluminum die-cast housings feature explosion-proof enclosures designed to contain internal explosions and prevent external ignition.
