Prism's advanced multistage pretreatment systems are perfectly suited for both batch and continuous operation. These perform a through cleaning of all metal parts to be processed, and provide superior corrosion protection. Reducing effluent load uses cascaded ranges for water conservation, there. Clean bath and bath life is achieved by incorporating continuous oil separation and phosphate sludge separation system. Flexible nozzles ensure easy adjustment of spray direction and air pocket direction. Quick release pipe coupling and nozzles aid easy maintenance.

Advanced F.R.P/S.S. systems are compatible with all solutions and therefore off high chemical resistance and prevention of mechanical damages, CHROME Free post pretreatment (de-ionized water rinse) facilitates better sealing.Water treatment plants are effectively employed to treat the effluent and they conform to local statuary requirements.
 
Prism offers CLEMCO’S grit blasting facility/grit recovery systems for removal of heavy MIL SCALE and rust, especially in H.R steel sections, for effective surface preparation prior to painting/powder coating with or without post dip/spray pretreatment.

Surface preparation can be done by multistage operations .The most commonly used multistage operations are 3 stage and 5 stage by following ways.
 

1. Spray Pre-Treatment: This method of pretreatment employs the use of an electrical motor to power a pump providing pressurized solution through a heating coil to a hose and hand held wand assembly.

The heat is providing by oil or gas fired burner to a heating coil that is part of this stand-alone system.

Advantages -> Can be used for large and bulk components.
 
Disadvantages -> Skilled labors required for troubleshooting.
