The serialised manufactured units range from the smallest size (TP-A1) with 3 kW of heat dissipation power to the largest size (TP-F6) with 500 kW per average.
Two fluids, of different starting temperatures, flow through the water oil cooler. One fluid flows through the internal tubes and the other flows around the tubes inside the shell. Heat is transferred from one fluid to the other through the tube walls, either from inside the tubes to the surrounding fluid or vice versa.
The Parker SWO Water Oil Coolers may be installed vertically or horizontally but both fluids must circulate counter to current flow. The cooler could be installed in the return line to the tank or in a closed circuit, and bypass isolation be set in place to allow for maintenance.
