Understanding Autotrol 400 Series Water Softeners

The Autotrol 400 Series represents a line of residential water softeners known for their reliability and efficient performance. These systems utilize the Autotrol 400 control valve, which has earned a reputation for durability and consistent operation in water treatment applications. Designed for household use, these softeners effectively address hard water problems through proven ion exchange technology.

Key Features of Autotrol 400 Series Systems:

• Autotrol 400 Control Valve: The heart of the system, known for its mechanical reliability and simple operation
• Efficient Regeneration: Demand-initiated regeneration systems that operate based on actual water usage
• Durable Construction: High-quality materials designed for long service life and consistent performance
• Flexible Sizing: Available in various tank sizes to accommodate different household requirements
• Minimal Maintenance: Simple design with few moving parts reduces maintenance needs and costs
• Water Efficiency: Optimized regeneration cycles that minimize water and salt consumption

How Autotrol 400 Series Softeners Work:

Autotrol 400 Series water softeners operate using the ion exchange principle. Hard water containing calcium and magnesium minerals passes through a resin bed where these hardness ions are exchanged for sodium ions. When the resin becomes saturated with hardness minerals, the system automatically initiates a regeneration cycle. During regeneration, a brine solution flows through the resin bed, flushing away the accumulated hardness minerals and recharging the resin with sodium ions, preparing the system for another cycle of water softening.
