A Piano Life Saver System from Dampp-Chaser Corp. keeps your piano on pitch and prevents damage from environmental effects, allowing optimum tonal quality and keyboard control. Piano technicians and the major piano manufacturers recommend installing the Piano Life Saver System to protect your piano, improve keyboard control, and maintain tuning stability. The System Humidistat keeps humidity levels consistent by activating the piano Dehumidifier during highly humid conditions and when the environment gets too dry, the System Humidifier replaces moisture inside the piano. Protect your piano's investment value by having our piano climate control System installed, out of sight, inside your piano to combat dry and highly humid conditions that can cause costly damage. The System is truly a piano lifesaver and must be installed by a professional piano technician to activate the warranty.
