String Wound Cartridge (VAREN)
CartridgeStringwound
Key Features
- Gradient-density media resists blinding
- Rigid wound build prevents telescoping
- Handles high-solids and viscosity swings
Overview
String-wound depth cartridge for rugged particulate reduction across water, chemical, and utility process streams
How It Works
Fluid flows outside-in through a tightly wound depth matrix; coarse outer layers capture larger particles while inner layers retain finer debris
Applications
- •General plant/process water and well/desal intake sand & silt removal
- •Chemical/batch prefiltration and coatings/inks guard service
- •Cooling, boiler makeup, and utility line protection at 0.5–100 µm
- •Data centers: TCS CDU filtration, FWS cooling tower, chilled water filtration
