Warewasher manufacturer Winterhalter has enabled its staff to offer foodservice venues a free water quality test during site visits.
The test determines the exact makeup of the local water in order to choose the right warewashing chemicals, dosage and water pressure for the best results and allowing an engineer to set the suitable wash parameters on the machine.
Paul Crowley, marketing development manager at Winterhalter UK said: “We’ve taken advantage of the lockdowns over the past year to train all our engineers and sales personnel in the science of water.
“It means they all have the know-how to do the tests accurately, and give expert advice to the customer so that the various elements that make up the perfect wash are in perfect alignment.”
The test can be done quickly, with the Winterhalter representative taking a sample of local water and checking the results there and then. Typically a water quality test might be done if an operator is having problems with their warewasher, with no obvious explanation.
Crowley said: “It’s not just ‘how hard’, it’s also important to know ‘what sort of hard’. By doing a water quality test at the very start of the buying process, we can ensure the customer gets the right machine, the right chemicals and the right results.”
The most common minerals in the UK’s water are calcium and magnesium, though others, such as iron, are also found in certain areas. Winterhalter’s water quality test also checks the levels of other particles such as chlorine. If the local water has a higher ratio of calcium and some iron, then the choice of chemicals, dosage and so on will be different than if there is, say, more magnesium.
For warewasher users who are having problems with deposits and residues on their crockery and glasses, Winterhalter offers another quick test that can establish the reasons and suggest the solution.
