If you’re running a commercial kitchen, installing a water-efficient pre-rinse spray valve will reduce water and energy bills, and help the environment.
Upgrade your pre-rinse spray valve and save
Pre-rinse spray valves are handheld rinsing devices used to remove food scraps and grease from dishes before they are placed in dishwashers.
This improves the cleanliness of dishes and reduces water and chemical consumption by enabling heated and treated water in the dishwasher to be re-used for more cycles.
Small and medium sized hospitality businesses can make significant savings by changing the Pre-rinse spray valves.
Water use in older Pre-rinse spray valves is typically between 10 and 15 litres per minute. They are usually fitted with a shower-type spray nozzle that relies on water volume for its cleaning action.
New WELS 6-star rated Pre-rinse spray valves use only 4 -6 litres per minute with added cleaning efficiency, performing the same tasks, using less water, in less time.
Pre-rinse spray valves generally deliver water at between 40-60oC, meaning energy savings of exchanging a valve delivering hot water from a gas system would be around 10.6GJ/yr per valve exchanged.
• cleans food off dishes faster and easier.
• saves up to two-thirds of water used by older models.
• reduces your water bill.
• uses less hot water, reducing your energy bill.
A simple yet impactful change is upgrading to a water-efficient Pre-rinse spray valve to reduce costs.
Replacing a Pre-rinse spray valve in your commercial kitchen can save between $160 - $352 per year and reduce your water cost by around $95 per year and energy costs by around $73 per year (for natural gas) or $256 per year (for electricity).
Over a year, this can save you thousands of litres of water usage and, therefore, hundreds of dollars on utilities.
