Pressure and Flow Results

 

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 loss of flow through the radiator.

Test Method

 

I have the line from my washbasin in the mudroom 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 and 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. And the tubing the runs back into the washbasin and down the drain.

 

 

Pressure Drop Data

Looking at the data table below, you see an extra digit in the PSI column that we are not used to seeing on radiators. Even with that said, we are not talking EK Supreme class restriction more like a Swiftech GTZ. Still, I really think the pressure drop on the CuV could be improved… and hopefully will in a future revision.

For many the data tables just do not equate to meaningful information, so we have some charted data below with the Swiftech MCR320 included for some comparison. Now if you want to see how the Cu1020V measures up against other triples, well you’ll have to see that in the Triple Radiator Comparison which will be updated shortly after this review goes live. The thing to take away from the restriction data, just be sure you are using high flow/low restriction components or as high flow as you can.

PSI Drop per GPM of flow

 

 

kPa drop per LPH of flow

If you’re a regular reader of Skinnee Labs than you’ll notice we dropped the mH2O per LPM, which I don’t think it was of much use as LPH seems to be the most widely used and kPa is the metric standard for pressure. It seemed like redundant charting anyhow, but if you want it back let us know.

The charts pretty much speak for themselves; the restriction is high compared to other triple radiators we have tested. Be sure to choose components with lower restriction to compensate and balance your loop out.

Now before we dive into the thermal test results and what you’ve all clicked on the link for lets cover the Test Specification and Methodology that was carried out through testing. I tried just linking to my Test Spec, but a few folks got there panties in a bunch because I linked instead of including it in the page. So much for trying to save on your scrolling finger.

Moving on…
