Add to Quote

The Widespray dispersant system comprises of a diesel driven pump set, a pair of height adjustable spray arms fitted with special nozzles, and a set of hoses for the suction of seawater, dispersant and discharge to the spray arms.

The Widespray dispersant unit can be diesel or electrically driven. The pump set is fitted with a flow meter and a recirculation valve that allows you to set the flow rate according to the desired application rate. For dilute spraying, an eductor is fitted which will give a mixture of up to 30% dispersant chemical in the seawater. This percentage can be varied.

The standard 4-6m spray arms can be fixed to the sides of a vessel, preferably near the bow. Each arm is supplied with 3-4 nozzles that provide an even spray pattern. The nozzles are provided with down pipes for vessels with a high freeboard.

The spray arms can be supplied in various lengths dependant on the size of the vessel the system is to be used on, which makes this extremely flexible. The system is also transferable between vessels if the need arises. The Widespray dispersant system is also available in an electrically driven set. The driver can be either single or three phase with voltages to suit. Starters and isolators can also be supplied as part of the skid or as separates for remote mounting.
