We recently had a customer that needed to build a temperature control skid that used a Dean pump to pump Therminol out of a storage tank and send it though a heating or cooling heat exchanger to control the temperature of the oil by the uses of control valves. The heating heat exchanger was a Standard Xchange shell and tube that used steam to heat the oil. The cooling heat exchanger was a Standard Exchange Brazepak with Glycol being used to cool the oil when needed. The system was designed to use using an Endress Hauser Coriolis Flowmeter, Dixon valves and gauges, along with two Neles Globe Valves to help control and automate the system. There was also an expansion tank mounted on the skid, but shipped separately to account for thermal expansion of the oil when heating.
