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 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.
