The independent "SGS" (SGS Testing & Control Services) has conducted tests on a ‘live-run’ Winterhalter multiple-tank dishwasher installed in the back-of-house of an internationally recognized 4-star hotel. The institute verified that it delivered the optimum hygiene result, and further computation proves that it was achieved with minimal operational cost. 

Winterhalter's full range of dishwashers have been designed to save energy and lower operating costs. Despite the proven factory tests and findings, one can always argue if the same piece of equipment will perform as satisfactory in a real condition especially in the challenging Asian kitchen environment. In a wide search of operational solutions to meet with new corporate directions of ‘green’ business practices, an international hotel chain in Asia was exploring into environmental-friendly and cost-efficient ways of commercial dishwashing which does not compromise its corporate hygiene standards, believed to be achievable only via high-temperature dishwashing methods. Winterhalter, the German commercial dishwashing specialist grabbed the chance to prove the effectiveness of its thermo-chemical disinfection dishwashing procedures in this event.  

Given the opportunity, Winterhalter went further from presenting factory tests and figures to installing a ‘live’ test unit in the hotelier’s. Therefore, one Winterhalter MTR multi-tank rack conveyor dishwasher was commissioned to run out of a premium 4-star hotel in the heart of Singapore. The ‘live’ unit, supplied in factory settings and neatly-packed with Winterhalter standard hygienic and cost-saving features, was connected to dishwashing chemicals catered by the hotelier’s existing chemical contractor. The unit was meant to be used by the stewarding team on a daily basis as the main dishwashing equipment in the hotel under ordinary operation conditions. Then, throughout a period of 3 months, the wash result was subjected to multiple tests conducted via wash item sampling by SGS Testing & Control Services in Singapore. The hygiene test reports from SGS show that all representative tests passed with optimal hygienic results, showing 0 cfu/10 cm² (‘cfu’- colony forming unit) on all wash items! 

Simultaneously, to measure the efficiency of the Winterhalter dishwasher in resource-conservation, water and electricity meters were installed at the unit to provide accurate readings of running costs in practice. Calculations based on actual meter readings resulted in tremendous savings of water and energy consumption reflecting a running-cost-savings of more than 50%, in contrary to machines of high-temperature disinfection. The result is a clear evidence that Winterhalter’s thermo-chemical disinfection dishwashers with its underlining hygiene concept, provides same hygiene result as high-temperature disinfection machines, besides keeping water and energy consumption significantly low and operational costs under control.
