Vent-Axia Demands The Best

Vent-Axia has introduced a new range of eDemand controllers designed to offer demand controlled ventilation to existing A/C speed controllable Fans and improve the performance and operating efficiencies of the Vent Axia range of fans.

Including Electronic Voltage Controller, Frequency Inverter single to three phase, Frequency Inverter three phase and Frequency Inverter single phase, Vent-Axia’s eDemand series bring more sophisticated levels of control to A/C fans installed in typical HVAC applications. They allow contractors to adjust ventilation operation according to demand readings gathered from CO2, temperature or constant pressure sensors. They also offer the capability to adjust and control fan speeds remotely to ensure more efficient operation and reduced fuel costs.

The new eDemand range is designed for easy set up and configuration. Quick start-up is ensured with each device’s pre-programmed modes. All eDemand controllers offer minimum and maximum speed set points, two programmable relay outputs; fault condition and master / slave. The controllers also incorporate LCD multi function displays with menu language options including English, German, French and Italian.

The eDemand controllers are designed for optimum reliability and safety. Controllers incorporate a thermistor connection for complete motor protection and all units are IP54 rated. An increase in electromagnetic motor noise can be a problem when applying speed control, but the eDemand series effectively eliminate these issues. Fans can operate in parallel with no risk of motor damage and screened motor cables are not required. The Electronic Voltage Controller also features a mains switch with by-pass function. All the controllers can be pin protected to save user settings and the Frequency Inverters are complete with integrated SINEFILTER for long-life operation.

Vent-Axia has also launched eDemand Auto Changeover Panels as part of the range for effective control over a wide range of standard AC speed controllable twin fans. The changeover panels have been designed to complement the new eDemand controllers and are fully compatible for installation with these products.
