LLB 317BE

Article Number 15640301

alvento LLB-series - active ventilation system with domestic hot water preparation integrated
All in one - ventilation, temper and domestic hot water.

The LLB-series stands for everything you need for comfortable living. Ventilation, temper and domestic hot water preparation. The recovered heat content of the exhaust air will be used to prepare the domestic hot water. If necessary, the supply air will be heated. A priority circuit ensures that the warming of domestic hot water has always the highest priority. The high efficient countercurrent heat exchangers achieve heat recovery rates of 80 %. The additional heating is done by the heat pump.

For faster installation, the system comes with the following components:

  • Countercurrent heat exchanger
  • Filled with flourinated greenhouse gas (R 134a)
  • Powder-coated (RAL 9006 white aluminium)
  • Double-walled case with 30mm insulation

 

Additionally delivery:

  • Air connection on top 160 mm
  • EC centrifugal fans for supply and exhaust air
  • F5 cartridge filter for supply and exhaust air
  • Supply air connection backside right
  • Domestic hot water tank 185l
  • Tube heat exchanger with 0,8m² exchanger surface for integration of a second heat exchanger
  • Controller
  • Optional iF7 pollen filter for the supply air
