A single "cold water method" defrosting session wastes up to 660 gallons of water.

In one year an average restaurant can use well over 170,000 gallons of water just defrosting food.

Every day, nearly a billion gallons of water is being wasted defrosting frozen food. You can be part of the solution.

The CNSRV WTR FOOD DEFROSTER  safely defrosts frozen food while using an average of only 8 gallons of water per complete defrosting session

    CNSRV WTR units are a staple in our retail establishments.  Not only do they support a sustainability method of thawing while reducing operational costs, but also adhere to food health and safety standards.  CNSRV WTR units preserve the integrity of our products so we can pass the quality on to our customers.  I recommend this product for anyone operating in the retail food or restaurant sector.

  • Craft House, Dana Point, CA.

    Using a CNSRV WTR Food Defroster has been a great help- especially when in a pinch. We don't defrost much food at Craft House, but when we need to, we are saving 1-2 hours on the process and able to not miss a step in prep or service. My team likes using the defroster so much that they've nicknamed it, "Thawmaster 5000". Thanks to CNSRV WTR.

  • Scripps Health Food Service, San Diego, CA.

    The CNSRV WTR Food Defroster was a great addition to our equipment list. Not only does it cut our defrosting time a considerable amount, the ability to do so while reducing our water waste is great. It also helps that it does all that while keeping us compliant with our regulatory standards with regards to food safety. The ease of use and clean-up is also a big plus.


How big is a CNSRV WTR Defroster?

The defroster is 20"x20"x20" and was designed to defrost a similar amount of frozen food that would fit in a standard 18" prep sink currently used for defrosting.

Is this safe for food contact?

Yes- the CNSRV WTR Food Defroster is NSF 51 listed for food contact. We recommend using vacuum sealed bagged food if possible for an easier clean up. But food that is not bagged is safe for use as well. Make sure to follow sanitizing instructions.

How quickly will my water savings pay for my device?

Based on current So Cal water rates ($0.02 per gallon) your defroster can pay for itself in as few as 45 uses. Check local water rates or email us for info on your area.

Where do I run the defroster?

The CNSRV WTR Food Defroster can fit in a 24" prep sink or be run on a drainboard/counter, freeing up sink space in the process. As long as there is an outlet, water source, and drainage nearby you can run it anywhere safely in your kitchen.

How does a CNSRV WTR Food Defroster work?

Fill the interior container with bagged frozen food and cold water until the water fully fills the interior container, overflows into the exterior container, and reaches the fill line of the exterior container. Turn the water off, and turn the defroster on. The defroster will safely recirculate water and regulate the temperature to make sure the water stays below 70F. Frozen food being fully submerged and agitated at a force greater than the standard faucet speeds up defrosting time tremendously.

There's little to no training needed. The only thing to keep in mind is the importance of never running the device when it's not adequately filled with water.
