REMKO WLT SERIES Wall-mounted units as 2-pipe system
High performance units for rooms with limited space

The unit suctions room air in through its front section, filters, cools and dehumidifies the air and then returns it to the room through its lower front section. For better air distribution, the air outlet louvres can be adjusted automatically in swing mode (WLT) or individually in a fixed position (WLT, WLT S).

A low-noise transverse current fan draws in the room air through an easily accessible filter. The copper-aluminium heat exchanger for medium temperatures up to 70°C located behind the fan provides for optimum cooling or heating performance. Any condensate occurring is collected in the condensate tray and conducted out of the device via a condensate tube. If the condensate cannot drain freely, a condensate pump can be integrated into the device according to the size and routing of the lines.

  • Straightforward installation above doors or in upper wall area
  • Removable and easy to clean air filter
  • Air outlet in swing mode or with individual fine adjustment
  • Integrated 3-way or 2-way valve subassembly
  • With infrared cabled control (not for WLT S)
  • Automatic restart after a power failure (not for WLT S)
  • Programmable 24-hour timer function (not for WLT S)

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.
