|When building your loop there should be a list of things that come to mind, flow and pressure should be near the top of that list. Pressure drop is the measurement of inlet pressure minus outlet pressure, or the pressure lost of flow through the radiator.
I have the line from my wash basin in the mud room hooked up to the gate valve controlling flow, which then runs into the King flow meter. The bottom port on the flow meter is the inlet, top port is the outlet. The outlet runs down to the Delrin T which I have Bitspower 1/2″ barbs on for the normal flow, and the negative pressure line connects via an EnzoTech 1/4″ fitting. After the negative pressure T, the component in testing is attached. I always use Bitspower 1/2″ fittings, that keeps everything on a common test platform…well from a fitting perspective anyhow. At the outlet of the component is the positive pressure T fitting, again with Bitspower 1/2″ fittings and an EnzoTech 1/4″ fitting for the pressure line. The tubing the runs back into the wash basin and down the drain.
For comparison and to play on the Thermochill Killer marketing, I’ve included the PA120.3’s pressure drop curve for comparison. Now do not take that openning statement the wrong way, the TFC360 has very low pressure drop compared to other radiators. The ThermoChill just has amazingly low restriction. I included three seperate plots of the two data sets, hopefully I have covered the vast majority of units that community uses.
