Air Proving Switches are used to verify the presence of airflow in ventilation and air handling systems to ensure safe and reliable operation. Connected to the safety loop, they prevent system operation if sufficient airflow is not detected, protecting connected equipment and supporting system safety. Airflow verification can be based on differential pressure or thermal measurement principles, depending on the application and sensitivity requirements. These solutions are used in industrial, commercial and residential duct applications as part of modern HVAC systems.

Controllers – precise humidity control for commercial applications Controllers are the central interface between your humidification system and the environment it serves. They ensure the right amount of moisture is delivered at the right time, helping maintain stable, comfortable and productive indoor conditions. Condair’s controller range is designed for reliability, flexibility and ease of use across commercial and industrial applications. At their core, controllers interpret humidity data and regulate humidifier operation to achieve the desired set-point. Simple on/off controllers provide essential safety and basic control, ensuring systems do not over–saturate ducts or spaces. They often include outdoor temperature setback and fan management functions to support efficient operation. More advanced modulating controllers deliver a variable control signal that adjusts humidifier output in proportion to the difference between current and target humidity. This enables tighter control and smoother responses in dynamic environments, such as variable air volume (VAV) systems. Integrated controllers with touchscreen displays further streamline commissioning and operation. They allow on-screen parameter adjustment, diagnostics and communication with building management systems via common protocols like BACnet, Modbus or LonWorks. In summary, Condair controllers provide the intelligence needed to maintain precise humidity levels, improve system performance and integrate seamlessly with broader building automation strategies.
