The series of airplex radiators has been expanded. From today you can buy the new pro and xt series besides the old evo series. The new radiators have parallel flat-pipes for a low flow resistance. These radiators also have a black coating and G1/4" windings.
Unlike the evo series the new radiators have M3 windings on the top and bottom.
The lamellae and pipes are made of copper while the casing is made of brass.

additional infos:
The new radiators already have been heavily discussed in the german thread due the fact that they are build by an other company (one of the wolrds largest radiator manufacturer). So don't wonder if you see these radiators at other watercooling companys.
Stephan said the next time there will be a better differentiation because a lot of users weren't happy to see that new xt/pro and old evo series are sailing under the same flag while evo is 100%
made in germany and xt/pro are not (the new ones will not have this slogan).
