TA units are delivered pre-programmed, tested and ready for installation. Connect the unit to the duct system, (connect any external components), connect the mains power, set the timer and fan speed in the controller and the unit is installed. General TA units are delivered enclosed in plastic and mounted on pallets. The units are fully wired internally. The controller is preset and has been test-run at the factory. Cables for external components (outdoor air dampers, etc.) are connected to terminals in the electrical connection box. The same applies to the valve actuator for the heating coil. Measurement and control accuracy The supply air sensor, operates with an accuracy of +/-0.4K. The accuracy of the controlled temperature is the same. Unit housing The unit housing and doors are made of galvanised sheet steel with 50 mm mineral wool insulation for low noise to the surroundings. The TA units have large doors that make inspection and maintenance easy. The doors are lockable. The electrical connections are collected in one place to make it easy for the installer. The controls display is connected with a 10 m cable (included) TA Big Unit Voltage V Fuse A Motor kw L P H W Coil kw A B C D E F G H We i g h t kg 6000 HW 400-3-50 3x16 1.

K-Fan EC Air Handling Units Maxi - Heat Recovery Unit Complete with integrated control system Low overall height Easy to service EU7 fine filter Available with LPHW or Elec Htg External Roof Cover (Option) The MAXI unit are designed for the ventilation of smaller offices, shops or similar premises. The unit is to be installed horizontally in the attic, above a corridor or similar locations. The EL (Elec heating unit) can also be installed upside down. The MAXI 1100 is manufactured from galvanised sheet steel with 50 mm insulation (30 mm for the inspection covers.) The 2 inspection covers with quick-release fasteners together with removable motors and heat exchange unit facilitate easy service and maintenance. The MAXI 2000 unit is supplied in 2 parts to facilitate easy installation. The MAXI 2000 is manufactured from galvanised sheet steel, double skinned, with 50 mm of Rock-Wool insulation. To facilitate easy maintenance, the access covers are fitted with quick release clips. In addition, the motors and heat exchanger re removable. The heat recovery efficiency is approximately 55-70%. The MAXI EL has an electric re-heater, whilst the MAXI HW uses a hot-water battery for re-heating. A by-pass channel with motorized damper is built into the MAXI 1100 unit and is an optional extra on the MAXI 2000 unit. The integral transformer has a 7-step choice on the MAXI 1100 for fan speed and five-step choices on the MAXI 2000.
