REMKO KWD EC COANDA SERIES Ceiling cassette with 60-degree air outlet

Ceiling cassettes with EC fans and Coanda screen

KWD EC Coanda ceiling cassettes use the physical properties of flowing air to evenly air-condition a room. Due to the specially designed unit cover, the air outlet is located at a small distance parallel to the ceiling, which creates a vacuum and increases the range. The flowing air thus falls into the room only slowly and draught-free.

Compared to conventional systems, a more even air distribution is possible with the Coanda screen. A significantly more pleasant feelgood climate is created without drafts.

EPA filter for air cleaning

As an option, the units can be equipped with an EPA filter (high-performance particle filter), which can meet particularly high demands on room air quality. This filters out about 99.5% of all suspended particles from the air, including pollen, mites, smoke particles and bacteria. This enables a particularly high level of air purity.

Areas of application of the EPA filter

  • Medical parctices
  • Clean rooms for measuing technology
  • Laboratories
  • Rooms with increased air quality requirements

Cooling load calculation for air-conditioners

The following rule of thumb applies when calculating the cooling capacity:
Approximately 30 W of cooling capacity are required per cubic meter. The cooling capacity for a room with a surface area of 28 m2 and height of 2.5 m can be calculated as follows:

28 m2 x 2,5 m x 30 W/m3 = 2.100 Watt (2,1 kW)

We recommend that you always calculate the cooling capacity for the room precisely.
