For use of the stator precision coolers (special variant) without stator covers or with segmented stator covers, matching end blocks are available without devices for clamping the cover strips. With the special variant, one of the end blocks has the connections for attachment to the machine cooling system as well as connections for the cooling profiles. The second end block has no connections for the cooling system of the machine, but only connections for the cooling profiles. For the special variant of the stator precision coolers, two different end blocks (LMFC3-R-IO and LMFC3-R-C) are always required.
