Hood-Type Dishwasher KASTEL HK850EPRS

A dome dishwasher cleans plates, glasses and cutlery by spraying hot water from rotating arms inside a sealed chamber. The dome lifts to load the basket, then closes to form a tight space where jets of water reach every surface. Heat and detergent break down grease, while rinse aid prevents water marks and speeds drying. The PRS system recycles rinse water into the next wash, cutting water and energy use without reducing cleanliness.

Load the 500x500 mm basket with two 50 cm racks for plates, one glass rack and two cutlery baskets. Close the hood to start the cycle automatically; the magnetic microswitch confirms the seal. Choose a cycle of 60, 120, 180 or 540 seconds on the electronic control panel. The LCD display shows time remaining and water temperature. Hot rinse at the end sanitises and dries the load. When the cycle finishes, lift the dome and remove the clean dishes.

The machine is built in stainless steel with a vertical self-cleaning pump that prevents blockages. Wash and rinse arms rotate in both upper and lower positions to cover the full basket height of 425 mm. A triple filtration system catches food debris before it reaches the pump. The boiler holds 11 litres and the tank 30 litres; each cycle uses 2.5 litres of fresh water. A thermostop system cuts power if the temperature exceeds safe limits, and the green function reduces energy consumption during idle periods.

The 6.75 kW power rating requires a 400 V three-phase supply, typical for heavy-duty kitchen equipment. The footprint of 760x793 mm fits a standard worktop space, while the height of 1494 mm (1969 mm with the dome open) allows loading from a standing position. The 144.5 kg weight means the unit is moved with a trolley or pallet jack.

Cleaning involves wiping the stainless steel surfaces daily and emptying the filters after each service. The self-cleaning pump reduces manual maintenance, but the wash arms should be checked weekly for blockages. The inlet hose (2 m) and drain hose (2.5 m) connect to standard kitchen plumbing.

The HK 850 E PRS is a dome-type dishwasher designed for high-volume professional kitchens, listed in the catalogue under heavy-duty warewashers.
