Winterhalter has launched the PT Workhorse passthrough dishwasher, featuring a series of upgrades and innovations designed to reduce energy and water consumption, and enhance usability and reliability.
In developing the new model, Winterhalter talked extensively to operators, dealers, consultants and business partners. The company was looking not only for the headline ideas that would deliver maximum benefits, but also for those small, attention to detail points that would both enhance reliability and make life easier for the operator.
Stephen Kinkead, MD of Winterhalter UK said: “A dishwasher breakdown is a crisis in a busy kitchen or bar. The tech guys have worked really hard on fine tuning or reengineering the components and systems to find ways to make the machine ultra-reliable. This dishwasher will cope with everything that’s thrown at it.”
In terms of the big ideas, the PT Workhorse is fitted as standard with an ‘EnergyLight’, recycling the energy from the waste water to heat the cold inlet water, claimed to reduce energy consumption by up to 10%.
The unit’s warewashing system and reengineered hygiene concept is said to deliver good wash results. New S-shaped wash arms create wash-fields that are designed to distribute water over a wide area, while the quadruple filtration system should ensure the wash water remains clean at all times. Winterhalter’s VarioPower variable water pressure regulation adjusts the wash pressure precisely to the type of wash items and how dirty they are.
Connected Wash also comes as standard. It allows operators and their service providers to monitor operation remotely. It warns when an issue arises, if a machine’s run out of chemical or a component is failing. It also gives advice on best practice, for example, letting operators know if the door is opened too early during washing, or if the machine isn’t closed down properly after a shift.
The PT Workhorse’s user-friendly controls includes a touchscreen said to be the only one of its kind on a passthrough model, and it acts as an intelligent keypad that prompts the user, rather than just showing digital icons.
In addition to its three standard wash cycle choices, it has special programs like eco and silent. The touchpad features single button operation and a language-neutral interface with self-explanatory pictograms – and users can still operate the screen even if wearing gloves. The interface also gives access to two ‘deep’ PIN-protected operating levels, one for chefs and owners and the second for service engineers. Since the software runs on Linux, it should be easy to update.
The ‘attention to detail’ ideas include the new Pump Protector, which is designed to offer an additional level of safety for the wash pump, guarding it from any debris that might find its way through. Kinkead said: “A damaged pump is a classic dishwasher glitch, which leads to downtime and costly repairs. The Pump Protector will go a long way to eradicating the problem.”
The redesigned strainer handle for the filter basket should make it easier to remove and replace, so the operator doesn’t risk putting their hand in the hot water. It should also make it simpler to clean inside the filter basket itself, so it’s easier to ensure hygiene and wash results.
Winterhalter’s new Auto Hood is operated with one touch of a button, but if there is something in the way a safety system kicks in and stops the hood’s descent. At the end of the wash cycle, the hood rises automatically. Kinkead added: “If you’re on a really busy shift, raising and lowering the hood every few seconds, the Auto system makes a significant difference to the workload. It’s hard work, made easy.”
The PT Workhorse comes in three machine sizes, M, L and XL. The PT-M is suitable for standard wash items, such as plates, glasses, cutlery and cups. The PT-L offers more space, for wider items such as trays. Both have a clear entry height of 440mm. The largest machine, the PT-XL, has an entry height of 560mm, so it can wash bulkier items such as GN2/1 trays and utensils.
