Product Structure

▼ Standard structure

① Coolant is drawn from the machine’s existing coolant tank

② The fluid is filtered

③ If equipped, coolant is stored in an auxiliary tank

④ If equipped with a chiller, the coolant is cooled in the auxiliary tank

⑤ In models with an auxiliary tank, a partition allows only clean coolant (free of sludge and chips) to flow to the high-pressure pump)

⑥ The coolant is then delivered by the high-pressure pump
