SWS-400 PRESS PARTS WASHER

The SWS 400 is the workhorse of the PRI line of washers. If you need to wash parts three shifts per day and cycle time is critical, this is the unit for you.

The PRI "Total Wash System" is an environmentally friendly press parts washing system designed to lower your operating costs, and reduce your emissions and hazardous wastes. The system includes a parts washer, wash solvent recycling unit, storage tanks and the other equipment necessary to provide an automated, low emissions "closed loop" wash and recovery system.

The PRI system cleans by using a four stage cycle including wash, rinse, recovery and dry. By using the penetrating action of the wash solvent, the ink coatings are removed and carried in suspension to the recovery unit. The recovery unit uses a distillation system to separate the ink pigments from the cleaning agent in an automatically controlled mode, insuring maximum recovery of the wash solvent.

All aspects of the washer and distillation unit performance are controlled and monitored by a Programmable Logic Controller. System activity is displayed on a screen for easy monitoring by an operator. The PLC control allows the wash and distillation system to run unattended and the operator to perform other duties while the unit is running.

The many benefits of this system include:

Safer than Hand Washing
     • No employee contact with liquids
     • Reduced respiratory exposure
     • No open containers of flammables

Environmentally Friendly
     • Lower VOC’s than handwashing or competitive wash units
     • Wash solvents are recycled on site
     • Reduces disposal volume

Cost Effective
     • Lower labor cost than hand washing
     • Less disposal cost
     • Reduces solvent inventories and purchases
     • Cleaner parts reduce press downtime

Easy to Use
     • Parts carts can be moved easily around the plant and roll directly into the wash chamber.

PRI washers can be used with many different wash solutions
     • Flammable Solvents
     • Combustible Solvents
     • PRI's HCS Cleaning Agents

Each company has unique cleaning problems. PRI will work with you to determine the proper cleaning solution for your application.

Many firms run combinations of water and solvent based coatings and have problems getting all the parts to come clean. PRI developed HCS cleaning agents for these applications and when it is desired to reduce emissions to the lowest possible levels.

Benefits of HCS:
     • Non Flammable Cleaning Agent
     • Very Low Vapor Pressure Agent
     • Recoverable in a Distillation Unit
     • Cleans both Water and Solvent Based Coatings
     • No HAP"s
     • Excels in wetting the surface, swelling the ink build-up, and carrying the dispersed material

Emissions from the system can be as low as .6 pounds per cycle when using HCS cleaning agents.
