STRUB Spindelfluid XLI++ Concentrate

Description
STRUB Spindle Fluid XLI ++ Concentrate is a corrosion protection concentrate for spindle and cooling systems. The passivators contained in the product provide long-term protection against corrosion for a wide range of materials. In particular, electrochemical reactions are prevented and materials such as aluminum, cast iron, nonferrous and ferrous metals are protected. Not suitable for galvanized, zinc-plated surfaces. In high-speed, highperformance motor spindles, the drive shafts can be cooled trouble-free with STRUB Spindle Fluid XLI ++ Concentrate. The spindle fluid can also be used in all other, less stressed systems.

1. suppresses electrochemical corrosion
2. excellent cavitation protection
3. low maintenance, long-term protection
4. very good heat dissipation
5. compatible with common sealing materials and plastics
6. special metal and corrosion protection inhibitors

Specifications and performance profile
Various approvals including STEP-TEC AG

Application
For the preparation of STRUB Spindle Fluid XLI++ Concentrate only tap/drinking water may be used which does not exceed the following limits.

Water hardness: 20°dH, chloride 100 ppm, sulfate 100 ppm.
If the listed water values are exceeded, STRUB Spindle Fluid XLI ++ Ready must be used. STRUB Spindle Fluid XLI ++ Concentrate is mixed as follows; 55 parts water and 45 parts STRUB Spindle Fluid XLI ++ Concentrate. Optimal conditions of use are temperature-stabilized cooling units to extend the service life of the coolant.
