The FTA VALVE
is used to control final sample temperature to enhance the accuracy
of on-line instrumentation. The valve can be attached to a heat
transfer coil which is immersed in a bath, or it can be mounted
on to a new or existing sample cooler to enhance the coolerĄ¯s
performance. The FTA valve is able to react to changes in both
the sample temperature and the sample flow rate automatically.
Other forms of temperature control such as secondary coolers and
isothermal baths work on the approach temperature principle which
requires readjustment by the system user as conditions change.
