5.1 Description
The Flowserve NX seal cooler is a shell and tube system used with single or dual
mechanical seals. It utilizes a counter flow pattern to enhance cooling efficiencies.
The objective of the seal cooler is to lower the temperature of process or barrier fluid
passing through the coil while cooling water passes through the case. It is designed
for installations close to the seal where space is limited.
