Description
Acoustic twin cabinet fans manufactured from galvanized steel sheet and internally lined with 25 mm thickness of fireproof acoustic insulation (M0). Incorporating a pitched lid, all are suitable for external siting.
Features and benefits:
- All models incorporate two S&P ECOWATT backward curved centrifugal fans, brushless EC motors with thermal overload protection.
- All fans comply with the efficiency requirements of the ErP Directive.
- Integral control unit providing automated run and standby by tacho/low current sensing, duty-sharing adjustable from 3 to 24 hours, (in 3 hour steps) and BMS output/remote fault indication.
- Remote on/off via volt-free contact and/or 230V signal.
- Variable speed control, manually via an optional secondary S&P REB ECOWATT or REB-CVF controller, or automated via a 0-10V signal from an external source.
- Installer-defined fixed speed control either continuous or on-demand (triggered by an external switch), or one, two or three speeds defined during installation to provide a minimum/middle/maximum speed ventilation system, the middle and maximum speeds being selected by an external switch/sensor (either volt-free and/or 230V).
- Integral over-run timer.
- Digital display of running, stopped and/or fault condition.
- Provision to operate a system damper actuator (can be supplied as an accessory).
