Details

The KBT fans size 225D4 IE3-280D4 IE3 are equipped with high efficient IE3 motors. The KBT fans have impellers manufactured from galvanized sheet steel with forward-curved blades. The casing is manufactured from double-skinned galvanized sheet steel and is insulated with 50 mm mineral wool.

The KBT fans have a swing-out door for easy inspection and service. The fan is isolated from the casing via connectors and anti-vibration dampers are incorporated into the base frame.

Motor protection is done by cold conductors (PTC), which have to be connected to an external motor protection device.

Please note: Speed control by voltage, i.e. voltage transformers, is not possible!

In accordance with Commission Regulation (EC) no 640/2009 of the European Parliament - eco-design requirements for electric motors - the new international efficiency classes are binding as of 16 June 2011. These guidelines defined by CEMEP and EPACT are regarded as international standard for energy-saving high-efficiency motors for frequencies of 50 or 60 Hz and make the use of IE3 motors mandatory. With this new and more efficient technology we offer our customers many advantages such as environmentally friendly operation, reduced energy consumption and hence lower emissions. IE3 motors have a higher efficiency even in part load operation and allow optimum adjustment to the operating point. In addition, the IE3 motors generate less noise and develop less heat, which has a positive influence on the efficiency and the cooling requirement of the motor. Please note: IE3 motors cannot be speed controlled by voltage, i.e. voltage transformers.

Average The Room Is A Normal Residential Room, Office, Reception Area Or Similar, Where There Is Not Overly Crowded With People, Computer And Office Equipment.
Above Average There Are Factors That Contribute To Additional Heat Being Generated In The Room E.G. Strong Lighting, Overcrowding With People And Office Equipment, Conservatory Type Room, Or Flat Roofed Room.
High There Are Factors That Contribute To A High Heat Load In The Room. E.G. Commercial Cooking, Much Computer And Server Equipment, Switchgear, Temporary Building With Thin Walls And Flat Room, Plain Glass Conservatory.
