Front Loading Spray Washers

Rotajet manufactures a full range of front-loading spray washers within our D series. We can supply each as either single stage washers or two-stage systems for washing and rinsing. For metal treatment or NDT applications, we supply three stage systems that include a final rinse stage.

Operation

Simply place the dirty components in the workbasket, this forms part of an integral wheeled frame that may be located on a trolley or fixed platform. The basket is fitted with rails designed to align with those located within the Rotajet spray washing machine. The loaded basket is then manually wheeled into the wash cabinet and the machine door is closed.  To commence the wash cycle simply press the green start button.

High cleaning standards are achieved by creating both direct and indirect (ricochet) impingement of a high volume of solvent or inhibited aqueous detergent solution (at 70-80° C) delivered at a nominal 5 to 6 bar* pressure from all sides. Reciprocating spray arms containing jetting, set to a V pattern, are located so that their sprays merge, providing complete coverage.

On completion of the wash stage, the cleaning solution is recirculated to source via perforated metal filter basket, powered by a pneumatically actuated, pivoting shed plate located in the liquid return passage. To ensure the longevity of your machine all filters are easily accessible and can be removed to allow for cleaning and servicing.

After the pre-set drain period, the shed plate bias changes to the rinse side and on proving, the rinse pump is activated. At the end of the cycle, the extraction fan is automatically energised to create a negative atmosphere within the wash cabinet. This assists the natural thermal draught to efficiently clear it of all steam. To protect the operator interlocks remain engaged until the pre-set drain and extract period have ended. At that point, the components may be removed to flash dry.
