Tunnel Washers

Effective Cleaning Systems for High-Volume Processes

The automated Sani-Matic Tunnel Wash is designed to thoroughly clean large quantities of process items such as pans, totes or trays, while also generating labor, water, and chemical savings.

Each Tunnel Wash system has high-impact, 360° adjustable spray nozzle manifolds positioned to provide complete cleaning coverage of the process item’s internal and external surface area. The automated system has programmable controls to automate water levels, temperature and conveyor speeds for efficient, repeatable results and cost savings.

The basic Sani-Matic Tunnel Wash modular zone configuration includes detergent and final rinse zones. The most common layout, however, is a three-section tunnel wash that includes a detergent wash, recirculated rinse and final rinse.

If you have a lot of similar process items to clean in a short amount of time, a Tunnel Wash may be the ideal system to increase your productivity, decrease your costs and provide you with Cleaning Confidence.

Quick Tips

Tunnel Washers are best for high-throughput part cleaning applications (250 – 500+ parts per hour).  

For lower volume part cleaning with more flexibility in the variety of parts cleaned, cabinet washers are typically a better solution.

Sani-Matic offers unique automated solutions such as a pallet/tray stacker to eliminate the need for an operator to manually load each part and another operator to unload each part.
