Flow Through (FT) Cooler
Tubing Connections
The Flow Through Cooler is designed to provide auxiliary cooling to a circulator or other
connected device. 3/8 inch female NPT fittings are provided on the rear of the unit for the
inlet and outlet connections. Depending on the application, tubing connections are made as
illustrated below:
When all connections have been made, fill the circulator with the cooling fluid to be used (see
Suitable Fluids
) and
start the circulator’s pump.
Application Notes:
1. Your application may require that fluid be pumped through one or more external closed systems (as in Figure
A). The only limitations on this type of configuration are the pump capacity and the Cooler’s cooling capacity.
2. The circulator must have enough heat capacity to compensate for the cooling effect of the Cooler. If the
heating is insufficient, the fluid will continue to be cooled below the circulator’s set point temperature, resulting
in poor temperature control.
3. Fluid may need to be added to the circulator reservoir to compensate for fluid pumped into the tubing, the
Cooler, and external device.
