Acoustic twin cabinet fans manufactured from galvanised steel sheet and internally lined with 25mm thickness of fireproof acoustic insulation (M0). All models incorporate two S&P ECOWATT backward curved centrifugal fans, brushless EC motors with thermal overload protection. 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.
Electrical supply: Single phase 230V-50Hz
Working temperature from -20ºC to +40ºC
