Air break tank and rinsing pump on Unica range.

5 March 2021 -

Rinsing at constant temperature and water pressure, regardless of external conditions.

On Unica40Abt and Unica50Abt the water is sucked from the boiler through a pressure increase pump and is sent to the rinse nozzles, making the machine independent from the mains pressure, thanks also to the presence of the Break Tank.

In this way, rinsing is guaranteed even with very low water pressures (less than 2 Bars).

The water temperature in the boiler, of 85 ° C, remains constant throughout the rinse, as the water in the boiler is restored after rinsing, avoiding mixing.

A break tank is often referred to as a ‘Type A’ Air Gap but must not be confused a non-return valve as it provides an entirely different method of operation.  

A Break tank may be fitted to a commercial dishwasher to prevent any possible backflow of dirty water (containing food debris, contaminants, bacteria etc.). from the machine into the fresh water mains supply. They are installed into machines to ensure that there is no chance of contaminating fresh water supply.

It works by feeding the incoming mains water supply into a separate tank first. This separate tank has an ‘air gap’.

From this tank, water is then fed into the dishwasher. This ensures that in the event of a fault in the dishwasher causing a backflow, contaminated water can only ever reach back into the break tank before it overflows through the ‘air gap’.

The result is that contaminated dishwater can never enter the fresh water inlet.

Do I need A Break Tank?

This specification is highly recommended on high-risk areas such as Schools, Care Homes, Nurseries or Hospitals where contamination of the water supply would be detrimental to hygiene and health.  

When water pressure is weak a rinse booster pump is absolutely necessary to get high level washing results.

Built-in feature available on request on glasswasher Unica40 and on dishwasher Unica50.
