Water Deionizing System

The Water Deionizing System purifies water straight from the tap to maximize battery performance and also includes a purity light which monitors the system's status.

The Water Deionizing System (WDS-1) purifies water straight from the tap to remove minerals and pollutants that can damage forklift battery cells. The WDS-1 is more that just a filter. The cartridge contains cationic and anionic resins, and as water flows through, it removes dissolved impurities electrostatically.

The WDS-1 produces entirely pure water that will maximize forklift battery performance. A purity light monitors the system’s status, and cartridges are easy to replace. A Water Gun (not included) can be connected to the output hose to water batteries directly, or the hose can be used to fill a water cart.

Tap water is full of impurities that can damage battery performance and decrease run-times. These negative effects may not be discernible at first, but in time, minerals and particles from unpurified water will form a damaging buildup on forklift battery cells. The Water Deionizing System from BHS prevents this outcome.

Maximize the performance and increase the longevity of forklift batteries by using Forklift Battery Watering Devices from BHS. Contact our sales team at 1.800.BHS.9500 to learn more about how a Water Deionizing System can protect your batteries.

Features & Benefits

  • Prevents poor battery performance from impurities in hard water
  • Complete solution to begin purifying water from the tap, including mounting plate and hose hanger
