APPARATUS AND METHOD FOR RENEWING COOLANT FLUID

摘要

An apparatus (10) for renewing coolant fluid and other similar liquids. The fluid is fed into an entry compartment (28) of the apparatus housing (12) and made to pass, thereafter, through a plate separator (30) disposed obliquely within the housing (12). The liquid passes between a plurality of plates (34) and exits from the separator (30) at a bottom end thereof. The liquid exits from the separator (30) into a processing compartment (32). Thereafter, it flows over the upper edge (58) of a weir wall (60) into a clean tank (56). While being processed, the liquid is treated by a biochemical bacteria retardant agent metered into the liquid from a source (82) through a line (84) by which it is conducted. Renewed fluid is recovered and held in a service tank (74) or returned to a sump.
