alira LWA-series - air/water heat pumps for outdoor installation

LW 251A-LUX 2.0

Article Number 100546LUX02

The stylish - Economical and powerful heating.

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 140A = ca. 16kW; LW 180A = ca. 20kW; LW 251A = ca. 27kW; LW 300A = ca. 30kW

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

  • The heat pumps are filled with fluorinated greenhouse gas R407C (LW 140A to LW 251A) / R448A (LW 300A)
  • Weatherproof

 

Additionally delivery

  • Electric heating element 9kW (LW 140A to LW 251A) for support during heating operation and domestic hot water preparation
  • Outdoor sensor
  • Electric soft starter (LW 140A and LW 180A)
  • Wall-mounted controller with microprocessor and integrated heating controller Luxtronik 2.0, diagnostic program and operating hours counter


For LW 300A, the electric heating elements must be selected specificially as necessary accessory. The control and sensor cable must be ordered separately as necessary accessories.
