Piano wood expands and contracts in response to changes in relative humidity, directly affecting tuning stability, the soundboard, pins and mechanics. The Dampp Chaser Piano Life Saver System keeps humidity levels around the instrument constant, 24 hours a day.
The system consists of three parts: a Humidistat control unit with a humidity sensor positioned just a few centimetres from the soundboard, a humidifier, and one or more dehumidifiers (depending on the piano’s size). The sensor automatically triggers the right device to maintain the ideal balance, silently and invisibly — installed inside an upright piano or beneath a grand.
Compared to a portable dehumidifier/humidifier, the system requires minimal maintenance (a water tank to refill roughly twice a month) and uses up to 11 times less electricity. It is available in 4 models, sized for upright pianos and for grand pianos across three length ranges.
