VAV Control Ex Schischek

VAV System Control in Ex Environments

VAV (Variable Air Volume) is a system with variable air flow that enables 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 air flow based on temperature, room occupancy, or other parameters.

Main Advantages of VAV Control:

✔ Energy Savings – minimization of unnecessary air and energy consumption
✔ Precise Temperature Control – possibility of individual regulation in different parts of the building
✔ Comfortable Environment – optimization of 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 protection of workers and equipment. Use of Ex certified actuators, controllers, and sensors allows effective air handling control in these applications:

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

Our range includes a wide selection of components for effective VAV system control in Ex environments, including actuators, controllers, and sensors with ATEX certification.
