BLOCK duct fan coil unit

Technical information

Mounting with a duct

The BLOCK duct fan coil unit is designed for tight spaces in the suspended ceiling. Typical applications include low suspended ceilings that do not have space for a machine that uses the same grille for intake.

The device is designed for adaptability, with the fan coil unit allowing three intake directions, depending on the mounting location.

  • intake from behind, ceiling mounting
  • intake from below, ceiling mounting
  • intake from the front, wall mounting

Telescopic intake and supply ducts of various sizes are available to enable more leeway in the choice of mounting height.

Draught-free and silent

The fan coil units are dimensioned in line with the cooling needs and noise level requirements. The coil size and route are determined in accordance with the efficacy and network temperatures. Fine-tuning is carried out with a smart automation system. Thanks to this, the desired cooling efficacy can be achieved precisely and quietly.

The cooled or heated air is directed into the room via the grille, which is located on the front, while exhaust air flows back via a duct located behind the unit. Directing supply air into the room along the ceiling across the entire width of the grille ensures draught-free cooling for the space.

Factory-set parameters allow easy automation

Chiller fan coil units come with factory-set parameters, and the devices are meticulously tested with our software tool before delivery to the worksite.

The automation is controlled via a wall-mounted controller, which can be easily connected to the fan coil unit with the automatic Startup Wizard tool. The Startup Wizard automatically configures the wall controller in line with the parameters of the fan coil unit connected to it, and no manual configuration is required. The deployment tool enables quick and error-free commissioning.

Elegant Viva grille

Available as an accessory, the Viva grille takes design to the next level. It is a polished and elegant solution that guarantees a stylish appearance.

Comprehensive accessory options

An intake duct connection is available as an accessory. Intake air is directed to a separate chamber that is not connected to the fan coil unit operation, and therefore fan speed does not affect pressure loss in the air side.
