It may be worth looking into. As the solvent is pumped over greasy engine parts, dirt and solids collect in a chamber at the bottom of the tank. The same solution can be used again and again, giving you more use out of each gallon of solvent. Any particulate is trapped for easy disposal. Reduces solvent emissions in the works area, improving working conditions.
Liquids can drain back into the tanks, reducing drag-out losses.
Reduces the amount of wastewater generated. Flush water is recovered and reused. After filtering the antifreeze to remove solids, you can put additives to counter the acidity that results from the breakdown of ethylene glycol in cooling systems. Additives may also contain other materials that can help the performance of the recycled antifreeze and prevent corrosion of the cooling system. Some recycling units can be attached to a vehicle's system and then filter and flush it.
