THE PROBLEM OF OUR CLIENT

PNR has been involved by the customer, who works in the food industry, in the design of a cleaning system for food tanks by spraying. The customer works with batch freezing cylinders that require cleaning in two places, one in the body of the tank and another in its terminal part.

PNR SOLUTION

PNR has proposed an innovative custom made solution for the specific needs of the customer: a double washing head with a single power supply. The cleaning performed by the customer consists of two phases, the first with water and detergent, and the second with water only.
The two washing heads assembled in this innovative mode are a fixed UAC washing head customized to wash the body of the tank, and a rotating UBC washing head, for washing the interstice through a dart jet.
