GEM designs, builds, installs and services water equipment for dialysis clinics in the Western United States. Founded in 1981 by Jack Enkowitz, GEM Water Systems had pre-acquisition annual revenues of approximately US$3.5 million.

“Adding GEM’s strong brand name and strategic Western Region presence to Mar Cor's leadership position in medical water enables us to better serve our national customers and further expand our business. We will be adding an outstanding team and base of business in a highly desirable region - one with a great concentration of dialysis clinics and healthcare institutions," said Curt Weitnauer, president of Mar Cor Purification. "We expect to achieve incremental growth with the addition of Mar Cor’s broad portfolio of products and services. Furthermore, the acquisition provides a foundation for a West Coast expansion of the Mar Cor service business.”
