VAV Control in Ex areas / HVAC

Product catalog summary

Volume Flow & Pressure Control in Hazardous Areas
This document outlines the use of ExReg-V controllers for managing volume flow and pressure in ventilation systems within hazardous areas, specifically zones 1, 2 (gas) and 21, 22 (dust). These controllers are applicable in building management, chemical, pharmaceutical, industrial, and offshore environments. Key components include a ventilation damper with an orifice plate and an actuator such as the ExMax-...-CY or ExMax-...-CYF with spring return.

Temperature & Humidity Control in Hazardous Areas
The ExReg-D controllers are designed for temperature and humidity regulation in similar hazardous environments. They support a temperature range of -40°C to +125°C and humidity from 0 to 100% rH. Installation can be done in ducts or rooms, with sensor lengths available from 50 mm to 200 mm. Additional valve actuators like ExMax-...-CY or ExRun-.. are required for full system integration.

Highlights and Benefits of ExReg Controllers

Direct use in hazardous zones 1, 2, 21, 22.
On-site configuration in hazardous areas.
Decentralized control reduces component needs and lifecycle costs.
No need for safety barriers or special wiring.
Integrated PID control structures.
Available in stainless steel or with marine coatings.
Predefined settings and damper characteristics for cost efficiency.
