Werecon W7 Acid Injection System

Werecon W7 Acid Injection System

The W7 Series pH systems offer a safe reliable way of adjusting the pH of irrigation water. The systems are available in many different models with or without fertigation capability. With the capability of utilizing virtually any type of pH control agent, including sulfuric, N-phuric, etc., the W7 series offers excellent flexibility. Due to the fact that the concentrated product is never under pressure, the W7 Series has inherently better safety and reliability than competing systems incorporating pressurized injection techniques.
