They are also known as rack dishwashers. They are mostly designed for a middle-size kitchen where undercounter type is too small, and the conveyor type is too large. Their capacity is about 80 racks per hour which is a pretty cool speed for most restaurants.

Low and High-Temperature Dishwashers

A dishwasher either uses low or high temperature to sanitise dishes. So the choice is just a matter of preference. For the high-temperature dishwashers, they utilise high heat of around 180° F for sanitisation. However, you might need to buy a heater booster if the machine cannot meet this temperature.

For the low-temperature types of dishwashers, they use a chemical to sanitise the dishes. They have a lower running cost since the cost of heating is reduced. However, you will have a problem with cleaning grease-laden dishware.

Check The Drain Pump

One of the biggest problems with using dishwashers is draining dirty water from the machine. In cases where the drain is higher than the position of the machine, you need to have a mechanism of pumping the dirty water. Otherwise, you will have a big problem with wastewater management. So when selecting a commercial dishwasher, you need to check it has a drain pump before buying. You don’t want to undergo another cost of buying these pumps separately.

Water Filters

So they are some of the crucial dishwasher accessories that you need to check while buying commercial dishwashers.
