ROOF MOUNTED AXIAL FLOW FANS HCTB / HCTT Series Range of axial roof fans with horizontal air discharge configuration available in 2 version: “B” models for air extract. “A” models for air supply. Base manufactured from galvanized sheet steel. Cowl manufactured from spun aluminium. The impellers for models 315 to 400 are manufactured from one piece injection moulded plastic, reinforced with chemical anchored fibreglass for additional strength. Models 450 to 1000 incorporate separate plastic blades locked within a die cast aluminium hub. Available, depending upon the model, with single or three phase motors in 4, 6, 8 or 4/8 poles. Motors All motors are IP65 (1) Class F (2) with thermal protection (3) and ball bearings greased for life. Electrical supply: Single phase 230V-50Hz (Capacitor located inside the wiring terminal box). Three phase 400V-50Hz. (See characteristics chart). All single phase models are speed controllable by voltage except HCTB/4-560, HCTB/4-630. All three phase models are speed controllable by autotransformer, except models HCTT/4-560, HCTT/4-630, Ø 710 to 1000. Three phase models, 1 speed motor, are speed controllable by inverter. (1) 800 to 1000 models are IP55. (2) Air stream temperature limits -40ºC to +70ºC (except models 800 to 1000 suitable for usage in environments from -30ºC to +40ºC. (3) 800 to 1000 models are not equipped with thermal protection. SUPPLY (type A) Specific applications Easy to install Supports to facilitate installation in the roof. High quality steel sleeve Ensuring the long life of the fan. Bird-proof guard. Roof mounted fans HCTB / HCTT Agricultural facilities Data centers Swiming pools Impeller dynamically balanced Impellers are dynamically balanced, according to ISO 1940 standard, giving vibration free operation. Aplications Industrial process ventilation, agricultural facilities, swimming pools and data centers. HCTT ATEX ATEX versions available for 3 phase models. For ambient working temperatures from -20ºC to +40ºC. Motors IP55, class F. - ATEX Flameproof - Gas In standard ATEX version flameproof motors are without thermal protection. If used with frequency inverter, flameproof motors with a PTC-type thermal protection must be specified at order. Only available for 800 to 1000 models II 2G Ex d IIB T4 II 2G Ex d IIB+H2 T4 (with motor Ex d IIC T4) - ATEX Increased safety – Gas II 2G Ex e II T3 - ATEX - Dust In standard ATEX version, ATEX motors for dust are without thermal protection. If used with frequency inverter, ATEX motors for dust with a PTC-type thermal protection must be specified at order Only available for 800 to 1000 models Suspended flammable particles and non-co ductive dust: II 3D Ex tc IIIB T125ºC Conductive dust: II 3D Ex tc IIIC T125ºC (with IP65 motor) To select HXTT ATEX refer to performance data or EASYVENT. Note electrical data may vary for ATEX motors. ww
