alira LW-series – air/water heat pumps for indoor installation

LW 300

Article Number 10078702

The Strong - Powerful and flexible in installation.

Operating limit flow temperature 20°C to 60°C
Recommended range of application heat source -20°C to 35°C

The heat pumps are recommended for the following total heating demand:
LW 140(L) = ca. 16 kW; LW 180(L) = ca. 20 kW; LW 251(L) = ca. 27 kW; LW 300(L) = ca. 30 kW

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

  • The heat pumps are filled with fluorinated greenhouse gas R407C (LW 140 – LW 251) / R448A (LW 300)
  • Wärmemengenerfassung
  • Electric heating element (LW 140 to LW 251) for support during heating operation and domestic hot water preparation  LW 300 hat kein Elektroheizelement eingebaut)
  • Heat pump controller Luxtronik 2.0
  • Electric soft starter

 


Additionally delivery:

  • Outdoor sensor

 

For the LW 300, the electric heating elements must be selectet specificially as necessary accessory.

NOTE
The operating instructions of the functionally necessary accessories such as hydraulic module or hydraulic station are stored in the "Downloads" tab under "ACCESSORIES".


* The data are only recommendations. Depending on individual circumstances, a heat pump with a lower heating capacity may also be suitable for larger buildings and vice versa. In addition, it is possible to connect several heat pumps together and thus increase the heating capacity. Finally, a precise individual calculation is required to select the really suitable system for the project.
