Cabin washing system
Type HWA-Highline

Subject to errors and technical changes!

Material

The machine is largely made of 18/10 chrome-nickel steel, material no. 1.4301.

The externally visible stainless steel sheet surfaces have a 320-grit finish.
The externally visible stainless steel profile surfaces have a uniform brushed finish.

Functional principle and design

The HWA Highline is a universal hood washing system for industrial use – designed for large-volume, robust and often heavily soiled items (e.g. Euro standard crates/baskets, GN containers, kettles, buckets/trolleys, baking trays, trays, moulds). It is not comparable to hood washing systems used in the catering industry – its design, power reserves and process stability are designed for large, robust and sometimes heavily soiled items.

Front loading: The items to be washed are placed in the basket (opening facing downwards) via the front loading flap, the ‘short’ or ‘long’ programme (washing times freely programmable*) is preselected and the process starts automatically after closing; removal is also via the front. Operation is designed as a one-person process.

Maximum load dimensions (intended use): width approx. 1,200 mm, length approx. 700 mm, height approx. 600 mm.

Washing system: Top and bottom driven washing arms are fed by a 4.0 kW stainless steel centrifugal pump (≈ 1,500 l/min, approx. 1.5 bar) – for thorough wetting and reliable dirt removal via 10 nozzle arms. In addition, two separate rinse arms operate in the same washing chamber, their rotation supported by a 0.75 kW rinse wash pump; the fresh water (ideally ~40 °C) is heated to ~50–80 °C in the integrated 11 kW boiler. The result: powerful main wash, followed by 4-sided rinsing with stable pressure, and clean surfaces without residues.

*Process times (individual): 
Two programmes (short/long) on the 2-stage toggle switch; stored times can be parameterised via time relays:
K6T = wash time (long) · K7T = wash time (short) · K8T = drain time · K9T = rinse time.
– Relay with 2 rotary controls: top time value (% of time unit), bottom time unit.
– Relay with 1 rotary control: direct value 1–20 s.

Process sequence

Washing – Washing tank ≈ 300 l, electrically heated (11 kW) to ≈ 50–55 °C.

Rinsing – 4-sided with fresh water; 11 kW boiler + 0.75 kW rinse pump ensure temperature and rinse pressure. ≈ 15–20 l fresh water/batch; multi-stage refreshment of the wash tank.

Drainage & removal – ‘Finished’ light illuminates, removal via front flap.

Highlights & advantages 

• Made for large items: 10 wash arms + 2 rinse arms, defined system pressure and high volume flows – even for bulky, heavily soiled items.
• Thermal and volumetric reserves: ≈ 300 l tank and 2 × 11 kW heating power keep temperature and performance stable where classic catering equipment reaches its limits.
• Time programmes to suit the dirt: freely adjustable washing, rinsing and draining times (K6T–K9T) instead of rigid short cycles.
• Predictable media consumption: ≈ 15–20 l/batch and multi-stage refreshing of the wash tank ensure consistent results and cost transparency.
• Hygienic, service-friendly design: rinse arms that can be removed without tools (knurled screw), accessible plate/filter technology, pump suction filter, pressure gauge ball valve (only open briefly), removable panels.
