As demand for hygienic design increases, CIP systems are redefining the meaning of clean.
"We routinely get calls for support for CIP systems that we installed
in 1963, '64," laughs Robert Beers, manager of food and beverage
engineering at Ecolab Inc. Mechanical support is no problem, but older systems
predate the advances in controls technology that have swept the equipment world.
"Rather than retrofit an old cam timer, it would probably be better to
put in a new I/O," says Beers.
