Newsletter – March 2016 




Through this newsletter, we wish to inform our esteemed customers that from now on the INTERNAL SECTION OF THE CORE TUBES for our standard Sea Water elements up to size 4040 and Brackish 4641 elements will be HEXAGONAL (see photo on the left) instead of circular (see photo on the right).

This change does not affect any datasheet specifications or element performance.



In case you wish to have machined circular section core tubes, please mention this in your purchase order indicating the desired diameter.

Yours Sincerely
