The quenching tank is a device capable of cooling just moulded pieces, before being sheared or sent to processes of recovery.
By taking advantage of the water circuit (tower or cooler), the system is capable to maintain an ideal temperature inside the tank, via the electronic instrument located on the control panel, in order to obtain optimal cooling of the cast for correct shearing.
