ACOUSTIC CABINET FANS CVB / CVT Series

Transcription

1 Cabinet fans manufactured from heavy gauge galvanised steel sheet and internally lined with melamine foam flame retardant acoustic insulation (M1). All models incorporate double inlet single phase direct-drive forward curved centrifugal fan fitted with anti vibration mounts and IP55 remote terminal box. All fans installed in acoustic cabinet fans CVB / CVT comply with the efficiency requirements of the ErP Directive. All cabinets can be installed outdoors as standard. Motors Available, depending upon the model, with single phase motors in 4 or 6 poles. Motors are IP44 or IP55 (1), Class F insulation, with ball bearings and thermal protection. Electrical supply: Single phase -5Hz. Three phase 23/4V-5Hz. All single phase models are speed controllable by tension (except CVB/4-27/2 373W). All three phase models are speed controllable by frequency inverter. (1) See technical characteristic chart. Working temperature from -2ºC to +4ºC. Low noise level Acoustic insulation of 7 mm thickness flame retardant (M1) melamine foam reducing the noise level significantly. Outdoor installation All cabinets can be installed outdoors as standard. Easy to mount All models are supplied with four mounting feet to facilitate installation. Flame retardant IP55 remote terminal box To ease installation and connection to external controls. Anti-vibration mounts Reducing vibration and noise transmission to the installation. Circular duct connection flanges In line circular duct connection flanges at the inlet and discharge. Acoustic cabinet fans CVB / CVT 639
