Hood type dishwashers (500x500) WHP-503 SANITARY

Sanitary hood type dishwasher for 500x500 baskets, with rinse pump, and double-insulated body.

99.999% elimination of bacteria

• Sanitary dishwashers reduce the risk of exposure to dangerous pathogens, ensuring the safety of both customers and employees in your business.
• This series not only disinfects, but also disinfects to the A0=60 level, in accordance with UNE-EN ISO 15883-1, a standard applied to medical equipment (A0=60 is the minimum requirement for human waste containers).
• Thermal disinfection begins at 65°C; therefore, these machines operate at higher temperatures.
• A0 refers to a value that expresses the cumulative effect of time and temperature on the inactivation of microbes during thermal disinfection. It indicates the machine's ability to eliminate microorganisms.

The machine offers two disinfection programs:

1. A0=60 for deep disinfection
2. A0=30 for lighter conditions

4 Versions of the model WHР-503 SN according to the additional equipment available, each in 50 or 60Hz.

DISPENSERS

• STANDARD FITTED RINSE AID DISPENSER - All machines with a rinse pupm are equiped with peristaltic dispenser instead of hydraulic.
• OPTIONAL - WASH AID DISPENSER - Peristaltic wash aid dispenser, fitted as a model version.

INTERFACE

• 2.8" TFT color display with backlight.
• Illuminated buttons and multi-colored START button that changes color depending on the machine's status.
• Color-coded status indicators.
• Display of operating parameters, such as tank and boiler temperature, or cycle time.
• Tank and boiler heater operation indicators.
• Self-diagnosis and error signaling.
• Timer function that allows the machine to turn on or off at a specified time.
• Energy saving mode (standby): Reduces energy consumption when the machine is not in use.
• User-selectable programs according to equipment use (glass, plates and bar), as well as machine-specific programs.
• Technical menu (access via password):
• View of all electronics inputs and action on outputs to facilitate rapid problem detection.
• Change of operating parameters, such as heating temperatures, wash and rinse times and etc.

CONSTRUCTION DETAILS

• Double-layer lid with thermo-acoustic insulation and metal guides to reduce lifting force and noise level.
• Fully stamped tank without welds or sharp edges. The washing chamber is free of internal pipes, edges and openings where dirt can accumulate.
• Easy cleaning of the internal parts without having to remove the basket support. The support can be tilted by 90°.
• The machine and its tables can be installed in a straight line or in a corner. It is also possible to change the working direction left-right or right-left.
• Upper and lower washing and rinsing arms.
• Maximum visibility thanks to the upper position of the control panel.
• Lid opening system with microswitch.
• Cycle start activated by removing the lid or manually (deactivated).
• Easy handling thanks to the handle surrounding the lid.

Dual-stage filtration system:

• Polypropylene pump suction filter that blocks even the lightest dirt, protecting the wash pump.
• Stainless steel tank surface filter retains coarse dirt.
• The filter can be easily removed without disassembling the wash and rinse arms.

Insulation in the boiler.

Dual-flow wash pumps: one inlet and two outlets, one for each arm, without the need for flow separation to avoid power loss and reduce noise.

Soft start: The cycle starts slowly and gradually increases to maximum speed to prevent light objects such as glassware and dishes from falling.

Wash/rinse arms. Duo-KLIP:

• Combined wash and rinse arm on the same level, made of stainless steel (X), preventing the two arms from intertwining.
• Low-friction and very light-weight arm, allowing all the power supplied by the pump to be used for washing dishes and not for rotating the arm.
• Wash and rinse openings designed with a specific geometry to reach the most inaccessible places. They spray the water precisely, achieving 10% lower water consumption, reducing electricity and chemical consumption and thus helping to minimize operating costs.
• The locking mechanism of the arm makes it easy to assemble and disassemble for cleaning.

RINSE PUMP as standard:

• Rinses even at low water pressure (1 bar). Water is drawn from the boiler by a booster pump and fed to the machine's rinse nozzles, ensuring an optimal and constant pressure.
• This system is independent of the water pressure, thanks to the presence of an "Air Break", which results in lower water consumption and therefore lower energy consumption.
• The water temperature in the boiler is constant during rinsing, as this water is not mixed with cold water from the tap during the filling phase.
• The air break ("Air Break") prevents non-potable water contaminated with rinse products, cleaning agents and food waste from flowing back into the water supply system. (Air brake check valve type A according to EN 1717/WRAS regulations)
• Precise dosing of rinse aid with constant water flow.

Thermostop:

• Starts rinsing when the rinsing temperature required for a hygienic washing result and proper drying of the dishes is reached.
• The rinsing cycle will be extended to a maximum time of ten minutes if the set rinsing temperature is not reached.
• Thermostatic filling (Available only for models with rinse pump):
• Speeds up the machine setup time, as the tank is filled with water preheated in the boiler, which is more powerful.

DRAIN PUMP or gravity drainage

• Performs the so-called volumetric rinsing: the dirty wash water is partially drained before rinsing, which makes it possible to: 1/Avoid useless waste of detergent by polluting the water more slowly and 2/Reduce energy costs during the wash water heating phase by continuously regenerating the wash water with warmer rinse water.
• Ensures the self-cleaning cycles of the machine, preventing the risk of bacteria growth.
• Versions without drain pump use gravity dranage.
