HEESS offers machines and systems for cleaning workpieces with optimum return of the quenching media for considerably reduced water and energy consumption. The hardened components are cleaned in two stages.

In the first stage, the clinging quenching oil is spun off by rapidly rotating the component. In the second stage, the rotating components are sprayed with industrial water and then dried with compressed air. The quenchant is fed back into the machine; there is very little carryover. The cleaning water is brought up to temperature by the residual heat of the components.

This eliminates the need for heating and washing additives. A phased separator then finally ensures cleanliness.
