New oil separator for tramp oil increases the service life of coolant and washing waterHighly efficient treatment of coolant for longer use

During operation of the machine tool, bedway oil, hydraulic oil or preservative oil gets into the coolant.

As soon as the coolant comes to rest, a large proportion of the tramp oil floats to the surface of the coolant as a dark brown or black layer and can be removed with an oil skimmer.

As many systems are in use 24/7, the tramp oil is often mixed with the coolant and does not float on the surface of the liquid. As a result, it cannot be removed with an oil skimmer.

The tramp oil introduced into the coolant encourages bacterial growth and promotes the formation of germs or fungal cultures in the system.

The coolant is pumped into the oil separator together with the mixed tramp oil. In the separation chamber with coalescence separator, the finely dispersed oil droplets are separated from the coolant and deposited on the surface of the coolant.

While the de-oiled coolant flows back into the machine’s storage tank, the floating oil phase is fed into a small separation chamber via an adjustable overflow. Any coolant that is also conveyed is returned to the system from the separator chamber, while the separated tramp oil flows into a storage chamber. With the exception of the feed pump, there are no moving parts and therefore no wear. In order to separate ferritic particles quickly, easily and efficiently, the system can also be equipped with a FRIESS magnetic filter.

The service life of the coolant can often be multiplied through continuous cleaning and maintenance. Germs, bacterial growth and the formation of fungi are reduced and costs for the purchase of new concentrate as well as disposal costs are reduced.
