FuelPolish Separators

Fine Filtration Plus Active Water Separation

CC Jensen FuelPolish Separators are designed for stored diesel and HVO fuel systems where water ingress is a constant or recurring risk. They combine CJC® depth filtration with integrated water separation in one offline fuel maintenance unit.

Like FuelPolish Purifiers, they continuously circulate fuel from the tank through the filter system and return cleaned fuel back to storage. The key difference is the additional separator stage, which collects separated water in a sump for monitoring and controlled discharge.

How It Works

Continuous Offline Fuel Cleaning and Water Removal

The separator works independently from the generator fuel supply line. Fuel is drawn from the tank by the integrated circulation pump, passed through the CJC® filter insert and separator section, then returned to the tank.

Water Separation

Designed for Fuel Systems with Recurring Water Risk

Water is one of the most common causes of stored diesel and HVO fuel problems. It can enter through condensation, deliveries, vents, damaged fittings or poor tank conditions. Once present, water can collect at the bottom of the tank and contribute to microbial growth, sludge, corrosion and blocked filters.

Automatic water discharge should only be used where it is suitable for the site, permitted by the project specification and connected into an appropriate containment or disposal arrangement.

CJC® Filter Insert Technology

3 Micron Absolute Depth Filtration

FuelPolish Separators use CJC® depth filter technology to remove fine contamination from the fuel. The depth filter media captures contamination through the full filter insert, not just on the surface, giving high dirt-holding capacity and effective fine filtration.

Product Selection

Choose the Correct Separator by Tank Type and Capacity

Use the product drop-downs above to select the correct unit for your belly tank or storage tank capacity. All FuelPolish Separator units include a control box as standard. The main selectable option is whether a drip tray is required.

Tank sizing is a guide only. Final selection should consider fuel condition, water ingress, tank design, duty cycle, pipework, control requirements and site operating conditions.

Control Box Included

Monitoring, Alarm Handling and Water Management

All FuelPolish Separator units include a control box. This provides operating modes, alarm handling and the additional monitoring required for separator water collection and discharge functions.

Drip Tray Option

Local Mounting and Leak Containment

FuelPolish Separators can be selected with or without a drip tray. The drip tray provides a mounting base beneath the unit and helps collect minor drips or leaks from the filtration assembly.

Where required, leak sensor float switches can be added separately to the drip tray area to provide local or remote leak alarm signalling.

When to Choose a Separator

Choose a Separator Where Water Is a Known Risk

FuelPolish Separators are best suited to installations where water ingress is constant, recurring or difficult to eliminate. For sites where routine fuel conditioning is needed but significant water ingress is not expected, a FuelPolish Purifier may be the simpler and more cost-effective option.
