The main difference between a commercial and an industrial dishwasher is the fact that a commercial dishwasher is mostly an off-the-shelf product albeit adapted to suit individual requirements, while an industrial dishwasher is a bespoke machine designed for a specific purpose. The term dishwasher does not accurately describe the process.
A commercial dishwasher is designed to wash a variety of utensils and implements used in the food service industry. An industrial dishwasher is designed to wash anything from engine conrods, to smokehouse trolleys; from eyeglasses to cheese moulds; from wheelie bins to crates etc.
The one thing they all have in common is that the cleaning process is all based on aqueous washing solutions. We do not use solvents. The cleaning process is a specific designed combination of time, chemical, temperature and mechanical interaction. Water pressure, volume, droplet size, spray angle all are specifically designed in an industrial dishwasher while a commercial dishwasher utilises the same principles throughout.
