HYFRA TRK 50-EF-S Kühlmittelanlage

Industrial coolant or oil purification system
Band filter system for coolant purification with chiller unit

The system was dismantled from a fully functional HERMLE C 1200 U machining centre.

This unit is a central system for cleaning and conditioning coolants (KSS) or oils, as used in metal-cutting processes (e.g. grinding, milling, turning). It combines mechanical filtration (band filter), fluid storage, and temperature control via an integrated chiller.
