Humidity Control

Dampp-Chaser Piano Life Saver™ System The Piano Life Saver™ by Dampp-Chaser, maintains your piano at an average 42% relative humidity as recommended by major piano manufacturers. Shrinking and swelling are minimized when your piano soundboard and wooden parts are kept at a constant moisture level. Your piano goes out of tune when the humidity in the environment surrounding the piano changes. The humidity levels in your home environment are controlled to some extent by the temperature. Generally, an air conditioner will remove some summer humidity, but the drop in humidity, when winter dryness sets in, presents a significant moisture change which will put your piano out of tune.

The Piano Life Saver™ System by Dampp-Chaser is made up of three basic components which work together to control the humidity levels within your piano, maintaining the recommended average 42% relative humidity, no matter what the external conditions are.

The Humidistat is the brain of the system, which senses whether your piano is too moist or too dry.
The Dehumidifier carries moisture away from your piano using warm air currents when humidity levels rise.
The Humidifier moisturizes the dry wood of your piano when the humidity drops below 42%. spacer

Dampp-Chaser components cycling The humidifier and dehumidifier cycle back and forth to maintain an average relative humidity of 42%. When the Humidistat senses that the wood is dry, it turns the Humidifier on. Then, when the Humidifier has provided enough moisture to the soundboard, the Humidistat turns off the Humidifier and turns the Dehumidifier on. The Dehumidifier carries away moisture from the soundboard on warm air currents until the Humidistat again senses that the soundboard is dry. The system again switches to the humidifying function. The cycle continues day after day, year after year, protecting your piano from external conditions.
