Why Add a Pre-Washer to Your Process?

Metal turnings often arrive coated in oils, coolants or machining debris that can cause blockages, contaminate wash tanks, or reduce melt quality. The Rotajet Pre-Washer ensures that every batch enters the main wash line pre-cleaned, stable, and consistent.

Reduces contamination entering the main wash tank

Lowers effluent and cleaning chemical usage
Improves overall wash line efficiency
Increases the value and usability of metal swarf

Delivers fast, reliable cleaning for heavily or lightly contaminated turnings

How the Rotajet Pre-Washer Works

1. Submersion Cleaning (Deep Penetration Wash)

Turnings are fully submerged in a heated, eco-friendly detergent bath. This allows the solution to penetrate deep into spirals and ridges, lifting oils, coolants and embedded contaminants from internal surfaces.

2. Impingement Wash (High-Pressure Surface Cleaning)

Powerful overhead spray bars deliver an aggressive, mechanical clean that blasts away grease and metal fines. The rotating screw conveyor provides continuous agitation, improving both surface cleaning and cycle efficiency.

3. Back-Flow Flushing (Final Internal Rinse)

As the spray liquid flows down the screw, it creates a constant back-flow stream. This delivers a final internal flush, ensuring every surface of the swarf is thoroughly washed before leaving the machine.
