Where did all the XFlow/Crossflow rads go?

Any idea why it's so hard to find a XFlow/Crossflow rad these days?

Probably because they are not very popular as they usually don't perform as well as non cross flow.

You can do a pseudo crossflow rad if you use standard rads with a drain port on the other end. What you need to do is split the inlet stream into two and have them enter both the ports on one side (if there are more than two ports then the point still remains) and have them meet up at the other endtank and exit the drain port. Performance hit is minimal as long as you have good flow. Target 1-1.2 GPM if you can to maintain turbulence in the rad now that flow is halved before entry itself.

Ok thanks, I'll see If I can find anything

Crossflow rads have the exact same performance as none crossflow, everybody just says they are worse without actually testing them for their selves. Plenty of tests on the internet and the crossflow performs just as well, and in some cases a degree cooler.

I stand humbly corrected sir - I thought they were worse. Learn something new everyday in this game. Lol

Can you please link these? I know personally that crossflow rads have a performance penalty (10-25% depending on the model) compared to the same rad but in the non crossflow design, and even rad makers agree with this.
