MasterTherm Heat Pump Noise Levels
How we limit the noise levels on MasterTherm units:
- Low-speed fans with super low noise level
- Quiet scroll compressors, located in the indoor unit on an anti-vibration frame
- Electronic expansion valve (EEV), ensuring a smoother and quieter operation
- Special soundproof cabinets.
Super silent DC fans made by Ziehl Abegg on all MasterTherm BoxAir units
