Technical details:

  • Some typical areas of application include:
    • retail chains,
    • showrooms and sales floors,
    • foyers
  • Heating and ventilation of retail outlets within suspended ceilings and with 625 x 625 mm suspended ceiling grids (600 x 600 mm on request)
  • Available in three models with a wide output range and also suitable for use with low temperature water
  • In rooms with a ceiling height of approx. 2.3-4 m , where the installation of unit heaters is not possible for aesthetic reasons
  • Fast delivery service: all standard units are available ex-stock.
  • Induction grille supplied as standard for fitting on site; brackets are ready-mounted
  • With hexagonal air outlet, settable in six defined angles
  • Base can be simply removed for maintenance purposes
  • Modular accessory components (mixed air)

Thanks to their "ultra-shallow" construction, Ultra units are ideal for use in areas, like supermarkets and other retail stores, exhibitions, entrance foyers with a ceiling height of between 2.3 and 4.0 metres.


Air induction from above has many advantages over air induction from below:

  • The motor is concealed and the accumulation of air under the ceiling is minimised.
  • Air induction from above is concealed through optionally available ductwork accessories with units mounted on a suspended ceiling.

There are specific Ultra units with heat exchangers for use with LPCW or for coolant, on request. The cooling model incorporates an additional condensation tray and pump although visually these units are identical to the heating-only units.
