Abstract
A box-type warewasher includes a housing defining an internal treatment space for receiving wares to be washed and a liquid sump below the treatment space. A wash liquid delivery system includes a wash pump having an input connected to the liquid sump and an output connected to deliver liquid to one or more spray nozzles of the treatment space. A rinse liquid delivery system includes a rinse pump for delivering rinse water to one or more spray nozzles of the treatment space. A condensing system includes a heat exchanger external of the treatment space, and a blower for moving hot moist air from the treatment space across the heat exchanger and back to the treatment space. A controller effects operation of each of the wash liquid delivery system, the rinse liquid deliver system and the condensing system. The controller is configured for carrying out at least one ware cleaning sequence in which: a wash spray operation is carried out by operating the wash pump; subsequent to the wash spray operation a rinse spray operation is carried out by operating the rinse pump; and subsequent to the rinse spray operation a condensing operation is carried out by operating the blower.
