BLAST WASH Underbench Dishwasher - AT50U

The Blastwash AT50U is a commercial underbench dishwasher that handles a full 500 × 500 mm rack, with selectable cycle times of 90, 120, 180 seconds or intensive, and delivers rinse water at 80–85 °C — performance typically associated with pass-through machines — in a cabinet that fits a 575 mm wide footprint and washes glasses up to 36.5 cm tall. Running on 240 V single-phase at 3.2 kW / 15 A and made in Italy, it is built for cafés, wine bars, restaurants and anywhere that needs fast, thorough warewashing in a compact underbench format.

Why operators choose the AT50U

• 500 × 500 mm full-size rack — the same rack format as pass-through machines, so standard rack dollies and dish tables work without modification
• Selectable 90 / 120 / 180 s or intensive cycle — match cycle time to service pace; drop to 90 seconds during a rush, step up to intensive for heavily soiled loads
• 80–85 °C rinse temperature — meets commercial hygiene standards without a booster heater, so setup is simpler and running costs are lower
• 20 L wash tank — holds enough water to maintain wash temperature across a full service, reducing recovery time between racks
• 36.5 cm maximum glass height — tall cocktail glasses, pilsners and carafes wash upright without special racks
• 575 mm cabinet width — slides into a standard underbench cavity alongside dishwash sinks or prep benches; no extra floor space required
• Made in Italy — European commercial-grade construction and component sourcing

Specifications

Venue suitability

The AT50U suits venues running a moderate-to-busy dishwashing load with limited floor space — cafés, wine bars, small restaurants, cellar doors and catering kitchens where a pass-through machine would be oversized but a domestic or light-duty unit would fall short. The 90-second cycle option keeps pace with bar service; the tall glass clearance makes it directly useful for beverage-focused venues. It is less suited to high-volume operations — hotel banqueting, large events kitchens, or venues washing 100+ racks per service — where a pass-through or conveyor dishwasher delivers the throughput needed without creating a bottleneck.

Frequently asked questions

What rack size does the AT50U use?
It takes a standard 500 × 500 mm commercial rack — the same format used in pass-through dishwashers, so existing rack dollies and dish tables are compatible.

How fast is the wash cycle?
Four selectable options: 90, 120, or 180 seconds, plus an intensive cycle for heavily soiled loads. The 90-second setting suits busy bar and café service where quick turnaround matters.

What temperature does it rinse at?
Approximately 80–85 °C, which meets commercial warewashing hygiene standards without a separate booster heater.

What is the maximum glass height?
36.5 cm — tall enough for pilsner glasses, cocktail glasses and carafes to wash upright without needing specialist racks.

What power supply does it need?
240 V single-phase, 3.2 kW, 15 A. A dedicated 15 A circuit is required; connection by a licensed electrician is recommended. A plumbed ¾″ water inlet and drain are also needed.

Does it come with a warranty?
Yes — the AT50U carries a 24-month warranty. Visit our warranty information page for the full terms that apply.

How does an underbench dishwasher differ from a pass-through model?
An underbench unit sits below the bench and loads from the top, making it compact for tight kitchens. A pass-through model loads from one side and exits the other, better suited to high-volume operations washing many racks per hour. The AT50U's 90-second cycle and full-size rack bring it close to pass-through performance in a smaller footprint.
