Explosion-proof HVAC controller

05 September, 2013

An explosion-proof controller for HVAC applications is available from Rotork Controls. The Schischek ExReg controller can control HVAC systems for variable air volume, pressure, temperature and humidity and minimise the number of components required. These controllers can be using extensively in hazardous areas, including Atex zones 1, 2, 21 and 22.

The compact design incorporates an internal PID control structure. Setting parameters is simple and automatically achieved for standard applications. The system provides support, especially during the start-up process, with many predefined settings and damper characteristics.

Intrinsically safe wiring is not required, and the ExReg is suitable for 24 V AC or DC supplies.
