The Piano Doctor

Humidistat - This is the brain of the system, which senses whether the wooden parts of your piano are too moist or too dry. Dehumidifier - carries moisture away from your piano using air currents when humidity levels rise. Humidifier - moisturizes the dry wood of your piano when the humidity drops below 42%.
These components cycle together to maintain the wood of your piano at 42% relative humidity. When the Humidistat, located less than an inch from your soundboard, senses that the wood is dry, it turns the power on the Humidifier. Then, when the Humidifier has provided enough moisture to the soundboard, the Humidistat turns off the Humidifier and turns the power on to the Dehumidifier. The Dehumidifier carries away moisture from the soundboard on 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.

Each Dampp-Chaser System Carries a 5-Year Guarantee The System must be installed by a qualified piano technician. Only your technician can be sure that each component is located for optimal effectiveness and protection.
