The Piano Life Saver System is made up of basic components which work together to control internal piano humidity levels, maintaining the recommended relative humidity and climate no matter what the external conditions are.
Through a cycling action, the Humidistat is calibrated to create a separate environment within the piano, producing a narrow range of average humidity. When the Humidistat, located less than an inch from the soundboard, senses that the wood is dry, it turns the piano Humidifier on. Then, when the Humidifier has provided enough moisture to the soundboard, the Humidistat turns off the Humidifier and turns on the Dehumidifier. The piano Dehumidifier carries away moisture from the soundboard on air currents until the Humidistat 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.
