The Guyson Marr-Lineconveyorised tunnel spray wash and dry systems enables tote bins and trays to be thoroughly cleaned and dried, removing production stains, oils, contaminants, and odours. This leads to improvements in quality by protection of components and all importantly minimises cross contamination from one usage of the tote bin to the next.

Marr-Line versions have previously been made where the wash tunnel can incorporate auto height adjusting air knives and automatic turnover bars which flip the bin through 180 degrees so allowing more of the water to be blown off the surfaces.
