The first Nu/Clean 800 X2L – Dual Wash Tank Cleaner is delivered to leading Aerospace Company. It was selected because in the words of their engineer


There are so many advantages to having a dual tank system. It gives the process engineer the option of running an independent chemical wash with their chemistry of choice; or running an independent DI Water wash; or running both a full chemical wash process with a full DI water wash process. Both tanks are heated independently so the temperatures can be set to what is ideal for each solution. The parameters for each tank are easily controlled via the touch screen software and changes can be executed instantaneously. There is a dedicated, recirculating isolation rinse between the two tanks to prevent any cross contamination from the chemistry wash tank to the water only wash tank.

Before the dual tank system, if you wanted to run a chemistry wash and a water only wash you either had to have 2 separate machines or you had to manually change the fluid in your single tank. Two separate machines require a bigger footprint, more electrical, water, drain, and exhaust connections. Plus those two machines are not integrated to work together. They have separate controls and often require more than one operator.
If you want to try to get away with just one cleaner for multiple processes, you’re going to have a lot of down time and probably some contamination issues. To drain, wipe down, and refill a tank can take hours. Then you still have to wait for the solution in the tank to come up to temperature. If you are running a chemistry wash and then want to switch to a water only or a different chemistry, it is a challenge to remove all of the first chemical. You have to empty the tank, flush the pumps, flush the spray bars, clean all the spray nozzles, and clean the conveyor. Even with all of that, some cross contamination is possible. If you’re an aerospace company, a military CM, or a medical device company, even a remote possibility of chemical contamination is not acceptable.


Every liquid used within the 800 X2L is either recirculated for use or sent to an evaporator via a closed loop sump system for a zero discharge disposal.

The Chemical Wash Tank is drained to a sump tank and then sent to an evaporator. The evaporator separates the water from any residues. The amount of residues is very small and can be easily disposed of according to environmental regulations. The Water Only Wash Tank is recirculated through a DI Water System to remove contaminants and returned back to the Water Only Wash Tank. If it is necessary to drain the Water Only Wash Tank, the water can either be routed to a sump tank to be sent to the DI System to be used again later or to the other sump tank and be sent to the evaporator.

The Isolation Rinse is closed loop with its own dedicated DI System. The Final Rinse Tank cascades into the Rinse Tank. Water from the Rinse Tank is sent to a second DI System to be cleaned and returned to the Final Rinse.

All of this recycling through closed loop systems and the minimizing of residual chemical through the use of an evaporator, makes the 800 X2L the most environmentally friendly cleaner available today. This also means the 800 X2L meets the environmental disposal requirements and emission regulations of virtually all environmental agencies.
