Thermal Considerations
bypass valve so that only a portion of the system flow goes through
the tank. The tank is required, because the system (even if charged ini-
tially with distilled water) will gradually acquire ions from the metal
components of the system and will increase in conductivity to unac-
ceptable levels. Finally, the system has a filling tank that allows the
system to be recharged and assures a positive head on the pump to
prevent cavitation. It is installed at the highest point in the water sys-
tem. Typically, the water loss is small enough so the makeup can be
tap water.
The entire system is stainless steel, plastic, or copper. Hoses are low-
conductivity rubber “pot line” hose made for the electrochemical
industry. These hoses ...
