QFDK Chilled water cassette ägir II

Innovating, elegant design, high control flexibility and easy maintenance are resulting in our ’ägir II’ series of chilled water cassettes. For aesthetic design features we can offer you two alternatives of grille modules: a steel grill-module (RAL 9010) and an ABS grille module with louvres (RAL 9003).
Every unit can be supplied with 1 coil for a 2-pipe system or 2 coils for a 4-pipe system and have the possibility of electrical heating elements. Each model can have fresh air intake, a remote air diffuser can be connected to the unit.

Each cassette is equipped with a condensate pump, very quiet and has a maximum head of 650 mm. In addition to the temperature and speed controls, automatic speed selection is also available. More than one unit can be connected to a single control, and the unit control panel can be installed in a position that facilitates the maintenance operation. An infra-red remote control is our latest trend. An ECM version using an innovative brushless synchronous permanent magnet electric motor is also available. The extreme efficiency, also at a low speed, makes possible a great reduction in electric.
