## Overview
Pleated Water Absorbing Cartridges are designed for water and particulate removal from a wide range of petroleum products where the presence of water is harmful or undesirable.

## How It Works
Liquid flows outside-in through pleated media; superabsorbent polymer swells to lock in water while the fiber matrix captures particulates

## Applications
- Diesel/gasoline storage polishing to remove free/emulsified water
- Turbine and engine lube-oil water removal to prevent bearing damage
- Hydraulic reservoir dewatering to protect pumps and servos
- Transformer/insulating oil water cleanup to maintain dielectric strength
- Fuel prefiltration on gensets to prevent injector corrosion
- Kerosene/jet fuel water knockout ahead of coalescers
- Compressor lube-oil water control after coolers/seals
- Coolant and cutting-fluid water/particulate control to extend life
- Pipeline/terminal sump cleanup with water scavenging
- Process chemical streams where trace water is harmful (compatibility check)
