Traditionally warewashers have been huge consumers of energy, but with advances in technology they now have the potential to reduce costs.

There's a lot to think about before investing in a warewasher, but the best place to start is the size. Operators need to not only consider the current throughput, but any future changes to the size of the business.

From under counter, pass through and hood type machines to simple glass washers there are various models to suit a range of businesses.

Environmental and efficiency issues are a huge part of the procurement process, so it's prudent to investigate consumption of water, detergent and electricity and consider their impact on operating costs.

Of course, price is also a major consideration, but operators shouldn't be tempted down the cheaper route. It's not just about the initial purchase price but the running costs and efficiency of the machines too. Models with a higher price tag are more likely to be made with higher grade components and they will last longer and provide better results too.

There are many essential features when it comes to warewashing equipment, such as rinse booster pumps which are vital for sites with low water pressure. Separate water softeners will be required if it's a hard water area and the machine doesn't have an in-built filtration system.

"Prewash units may be required in heavy usage sites or as part of a pass through system," says Bob Wood, director of DC Warewashing and Icemaking Systems. "Operators may also want to consider compartmentalised glass baskets to reduce breakages, particularly of high stemmed glassware."
