Hood-Type Dishwasher KASTEL HK850ESIPRS

A dome dishwasher cleans by spraying hot water at high pressure through rotating arms inside a sealed chamber. The dome lifts to load the basket, then closes to form a tight wash space. Heated water dissolves food residue, detergent breaks down grease, and rinse aid prevents water spots. The cycle ends only when the water reaches the set disinfection temperature, ensuring hygiene for every load. This method removes the need for pre-rinsing and handles the volume of a busy service without slowing the kitchen.

Load the 500 x 500 mm basket with plates, glasses, cutlery, pans, pots or GN 1/1 containers up to 425 mm high. Select a cycle from 60, 120, 180 or 540 seconds to match the soil level. The hood closes automatically and the machine starts; the cycle runs until the Thermostop system confirms the rinse temperature. When the hood is lifted, the machine stops and the basket is ready to unload.

The dishwasher is built entirely of stainless steel for strength and corrosion resistance under daily use. The wash and rinse arms are stainless steel, the hood is double-skinned and insulated to cut noise and heat loss, and the chamber walls are reinforced to withstand the pressure of the pump. A triple water filtration system traps food particles before they recirculate, and a self-cleaning vertical pump keeps the hydraulic system clear without manual intervention. An automatic end-of-day programme flushes the wash tank to reduce build-up.

Electronic Smart Interface controls let the operator choose the cycle, monitor progress and adjust settings. The Start/Stop hood function links opening and closing to the wash process, so the machine pauses when the hood is raised. A detergent and rinse aid dispenser doses chemicals precisely for each load, and a non-return valve prevents backflow into the water supply. Multipower technology balances energy use and wash performance across different loads, while the PRS system with atmospheric boiler and break tank maintains a steady hot water supply.

The 400 V three-phase supply powers a 6.75 kW element, suitable for a dedicated circuit in a commercial kitchen. The 126 kg weight requires a stable floor and a trolley for moving. The footprint of 760 x 793 mm fits under a standard worktop, and the 1494 mm height allows clearance for the hood to open fully. The 30 L capacity refers to the wash tank volume, not the basket size, and determines how much water is heated per cycle.

Cleaning follows from the parts named. The triple filter basket is removed and rinsed daily. The wash and rinse arms are checked for blockages and wiped clean. The detergent and rinse aid reservoirs are refilled, and the end-of-day self-cleaning programme is run to flush the tank. The stainless steel surfaces are wiped with a damp cloth and mild detergent to prevent scale and grease build-up.

The HK850ESI PRS is a dome dishwasher with a 500 x 500 mm basket, supplied with two plate racks, one glass rack and two cutlery holders. A water softener is available as an optional extra. The product sits in the professional dishwashing section of the catalogue, under hood-type machines.
