Fisher Pre-Wet System

Fisher Pre-Wet System

Activate Your Salt and Use Less

De-icing is where the money's at, but salt and other de-icing materials come at a cost. The new FISHER® pre-wet system makes better use of your inputs by activating the material just before it hits the spinner. Pre-wetting salt starts a chemical reaction that accelerates melting so you see results faster. As an added benefit, pre-wet granules bounce less, which means more of your material goes where it's supposed to. In fact, studies show pre-wetting can reduce salt application rates by 20-30%.

The updated FLEET FLEX electric hopper spreader control for the STEEL-CASTER™ and POLY-CASTER™ hopper spreaders includes a pre-wet accessory button which provides simple on/off* operation, allowing the operator to choose when to apply brine while spreading.

For operators who want additional flow control from inside the cab, a separate in-cab, full-featured control option is available, featuring a flow-control dial and warning lights that alert the operator of a clog or if the tanks are empty.

*On STEEL-CASTER gas and hydraulic models, the on/off switch is incorporated into the master accessory harness control panel.

Pump System

The pre-wet system is supported by two different pump systems.

When using the simple on/off control, the flow rate in the pump is set manually using the needle valve. Activation is controlled with an on/off switch in the cab.

When using the full-feature control, the manual, single-needle valve is replaced with two pressure sensors, a high and a low, to detect a clog or empty tank.

A corrosion-resistant, fully enclosed housing protects the pump, electronics and valves from the elements.

Quick-Disconnect Coupler

Easily remove the chute and spray bar with the durable, quick-disconnect coupler.

*Available on STEEL-CASTER™ hopper spreader models only.


Spray Bar

Easy-To-Maintain Spray Bar

On STEEL-CASTER™ hopper spreader models, the spray bar is located inside the chute, reducing the likelihood of a clog and making it easier to clean.
