T1 heat-pump dryer:

Tumble drying as you’ve never heard it before. Our SilenceDrum is whisper quiet, thanks to a special design that can reduce perceived noise spikes in half – in particular when drying garments with buttons and zips. The inclusion of insulating strips in the drum prevents rattling noises from escaping, so you are free to operate your dryer close to your living spaces without disturbing the peace.
