WS Series Water Softener Cartridge
Engineering summary from PDF text extraction for WS Series Water Softener Cartridge. Verify every value with the OEM datasheet.
Summary
Product identification
The WS Series Water Softener Cartridges are designed for optimal contact between water and resin surfaces, ensuring maximum ion exchange. They utilize FDA-grade, sodium-based, non-solvent rinsed softening resin and single-use resin technologies. The internal expansion pad minimizes movement and eliminates bypass. These cartridges are designed for low water usage applications, delivering softened product water to protect sensitive water delivery equipment.
Available models:
- WS-10
- WS-20
- WS-20BB
Key features:
- Manufactured with FDA grade softener resin
- Available in a variety of sizes for multiple applications
- Utilize single use resin technologies for maximum life
- Sodium form resin
WS Series cartridges are compatible with PENTEK’s SlimLine®, Standard, and Big Blue® housings. They are suitable for applications desiring low hardness and scale deposits, and provide superior performance for medical equipment, coffee and espresso appliances, low volume beverage, and commercial food service machines.
Operating limits
- Capacity range: 750 to 4,500 grains (CaCO₃)
- Temperature Rating: 100ºF (37.8ºC)
Feed water
These units effectively treat water in applications desiring low hardness and scale deposits.
WARNING: For drinking water applications, do not use where the water is microbiologically unsafe or with water of unknown quality without adequate disinfection before or after the system.
Product water
The cartridges deliver softened product water, helping to protect sensitive water delivery equipment by reducing hardness and scale deposits.
