Adler AD50-DPSO 500mm Undercounter Dishwasher Drain Pump & Softener

The Adler AD50-DPSO is a 500mm basket undercounter dishwasher designed for commercial kitchen use. It comes fitted as standard with an integral water softener, a drain pump, and a chemical dosing pump — combining three components that are commonly specified separately on lower-specification machines. The result is a unit that is ready to work from installation, without relying on an external softener or gravity drain.

In a working kitchen environment, the 60-second cycle option allows throughput of up to 60 racks per hour, which translates to meaningful plate capacity during a busy service. For operations where speed is less critical than thoroughness, longer cycle options are available, giving the operator practical flexibility depending on the load and soil level. The stainless steel interior and exterior stand up well to the cleaning chemicals and daily workload typical of a commercial environment, and the double-insulated door helps maintain wash temperatures without excessive heat loss.

The practical advantages of this configuration are worth considering carefully:

• The integral water softener protects the wash system in hard-water areas, reducing limescale build-up and the associated maintenance burden.
• The drain pump removes the requirement for a gravity-fall drain, giving more flexibility in where the machine can be positioned.
• The chemical dosing pump dispenses detergent and rinse aid accurately each cycle, reducing waste and inconsistent results.
• A 340mm clearance height accommodates standard commercial crockery without adjustment.
• The machine is supplied with dish racks, open racks, and a cutlery basket, so it is operational from day one.

Installation requires a single-phase electrical connection, a mains cold water supply, and a drain point. The drain pump gives flexibility on drain positioning, but a water supply and adequate ventilation near the unit are still required. As with any undercounter dishwasher, it is worth confirming the available height and depth under the counter before ordering. This model is best suited to kitchens without a central water softener system — if your site already has softened water, a version without the integral softener may be more appropriate.

The AD50-DPSO is well suited to cafés, small restaurants, pub kitchens, staff canteens, and similar operations producing moderate plate volumes through a service. It is a practical mid-range choice for sites that need reliable throughput without the footprint or cost of a pass-through machine. For high-volume sites turning over significantly more covers per service, a higher-capacity machine would be worth considering instead.
