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.
