To enlarge the picture please click

Our cooling concentrate AquaTec 7650 is a water-soluble EP cooling lubricant, developed especially for the general chipping of aluminum alloys. It is also suitable for cast materials and higher alloyed steels. Particularly when working with tools with guide bars (Reaming & fine boring) one can obtain an excellent surface quality. AquaTec 7650 is free of amines according to the TRGS 611 and does not contain organochlorines.

AquaTec 7650 is foam-inhibited and enables long emulsion lifetimes leading to low maintenance costs. When mixed with water, it forms a solution of high stability, excellent rinsing effect. AquaTec 7650 can be solved in soft and hard water qualities. This cooling concentrate is harmless to the skin compatibility and has a pleasant odour.

AquaTec 7650 is suitable for the use of single filled machines as well as for central systems.

Emulsions must not be mixed with pure drinking water, otherwise they lose their stability. Instead add a very low concentrated emulsion of the used emulsion. The use of deionised or demineralised water for refilling increases the stability of the emulsion, avoids the formation of deposits and reduces the consumption of the concentrate.

Before preparing a new solution the system must be cleaned thoroughly with a system cleaner. Used solutions must be disposed by means of legal waste disposers.
