1. The Oil Skimmer removes floating oil on coolant surface by a stainless steel plate, preventing coolant from deterioration.
2. Equipped with oil/water separating tank, removing floating oil only and clean coolant draining back to coolant tank.
Tramp oil and sludge is drained all together, preventing coolant's deterioration in efficiency. Due to oil and residue mixed on the surface of the coolant, air is isolated and results in corruption, lower processing effeciency, smelling and rust. Because of it, sludge separator is the best solution.
