The Rotork Schischek ExReg-D is a compact, explosion-proof temperature and humidity regulator. It provides PID-based control for safety-critical HVAC systems installed in hazardous areas (ATEX/IECEx Zones 1, 2, 21, 22). The unit processes signals and controls actuators without requiring intrinsically safe wiring or additional modules.

Key Features

• Anti-Icing Control: Programmable PID for heating/cooling control over explosion-proof actuators (ExMax/ExRun).
• Robust Design: IP66 aluminum housing with an optional seawater-resistant coating or stainless steel version.
• Visual Feedback: Backlit LCD display alongside status LEDs for alarm and power indication.

Technical Specifications

• Measuring Range: -40°C to +125°C, 0 to 100% rH
• Power Supply: 24 V AC/DC (integrated Ex-e terminal box)
• Housing Protection: IP66

Applications

• HVAC in industrial and offshore hazardous locations
• Air flow control in chemical and pharmaceutical plants
• Ventilation monitoring in polluted and wet process areas
