Nelsen Signature Series AIO® w/Control Flow Technology™ Valves
The Nelsen Water Solutions Signature Series AIO™ features a unique patented process. Most systems
purge the air pocket in the tank violently during the regeneration process potentially damaging plumbing
and creating an excessive amount of noise. Our patented-process slowly releases the air pocket during
regeneration before replenishing the tank with a fresh pocket of air. Additionally, the meter control will
delay the regeneration process and air release if water flow is detected. Once water flow stops, the
regeneration process begins slowly releasing the air from the system. On some competitive systems,
water use will prevent the release of air due to the internal design limitations of the control valve or
violently release the air once water flow stops.
