Frequently Asked Questions 

What is your lead-time? 

Our lead times  are generally 12-16 weeks. All our washers are custom built to meet a variety of tray and bin sizes. We can help you determine which model will work best for your needs. 

Does the washer have a warranty? 

Yes, we provide 1 year on all purchased components like motors and pumps. Everything else is a 5 year warranty on workmanship.

What is the maintenance ?

Cleaning the filters is the most critical, it prevents the nozzles from plugging up.. Cleaning the washer on a regular routine is critical as well to prevent buildup of algae.  The rest is general tightening of internal components to prevent trays from going off line during the washing process.

How do I remove and clean the nozzles? 

Nozzles are removed with a wrench. They can be blown out using 100 psi air gun. Reverse the procedure to replace them.

What process is used to clean a try? 

The washer uses water contained in a 60 gallon tank to wash the tray. This removes any large and small debris. The dirty water drops back into the tank and the large particles are caught in a mesh tray for easy removal. The large bag filter is for microscopic particles. The tray goes through a rinse section using fresh tap water next. It continues on to a sanitation section where chemicals are spayed on the tray, again using fresh water. All the drains lead back to the main tank to conserve water usage. Next the tray passes through a large air drying process before exiting through the end of the washer.

How do we clean the Washer? 

You start by emptying the 60 gal holding tank. You can remove all the side doors. Manually remove any large debris, then power wash the washer down. Please ensure that you do not spray the electrical panel.
