- Attenuators (optional)
Axial high-temperature fans, manufactured from hot dipped galvanized steel sheets
Main system control panel located on the skid and pre-wired to the fans and dampers
Optional automatic transfer switch module mounted on the common plant skid.
Built-in low-speed daily ventilation mode
The fans and motors are rated at 300°C for 2 hours and are fully tested and certified to the requirements of EN12101-3. The fans are mounted in series onto a pre-assembled module using anti-vibration mounts. The fan assembly is mounted onto skids fitted with adjustable feet for mounting on a suitably prepared roof area.
An integral motor control centre provides the control and monitoring of the extract fans, dampers, doors and stairwell AOVs through the communications network. The operation of the fans is monitored by current sensing so that in the event of fan failure the standby fan will be automatically started.
Auto changeover of mains and standby power supplies is provided by an optional automatic transfer switch (ATS) module mounted on the common plant skid where required. The ATS is fully compliant to BS EN 8519:2010 with a bypass feature to maintain a fully operational system during maintenance work.
