VAV System Control in Ex Environments

VAV (Variable Air Volume) is a system with variable air flow that allows efficient ventilation control in buildings according to current heating, cooling, or air quality requirements. VAV Control ensures optimal air distribution using electronic controllers, actuators, and sensors that automatically adjust the air flow based on temperature, room occupancy, or other parameters.

Main Advantages of VAV Control:

✔ Energy Savings – minimizing unnecessary air and energy consumption
✔ Precise Temperature Control – allowing individual regulation in different parts of the building
✔ Comfortable Environment – optimizing air flow according to actual needs
✔ Integration into Building Management Systems (BMS)

Use of VAV Control in Ex Environments

In explosive hazard environments (Ex zones 1, 2, 21, 22), VAV control is crucial for ensuring safe ventilation operation and protecting both workers and equipment. Use of Ex certified actuators, controllers, and sensors enables effective air handling in these applications:

• Chemical and Pharmaceutical Industry – ventilation control in laboratories and production halls where it is necessary to remove vapors from chemical processes.
• Refineries and Petrochemical Plants – ensuring proper air flow in operations with explosive gases and liquids.
• Paint Shops and Spray Booths – regulating air supply and exhaust to minimize the concentration of volatile substances.
• Flammable Substance Warehouses – maintaining a safe atmosphere by eliminating excessive concentrations of gases or dust.
• Clean Rooms in Ex Zones – controlling ventilation in environments with controlled atmospheres, such as in the electronics or pharmaceutical industries.

In our offer, you will find a wide selection of components for effective VAV system control in Ex environments, including actuators, controllers, and sensors with ATEX certification.
