‘The German Modified Coltrisub’ assembled by Seemann Sub GMBH BA240-01, SA240 T
Note:- This product appears to be obsolete & is no longer listed on the Seemannsub web site. Don’t worry though, since the block is entirely Coltrisub, and spares are easily available.
It is possible to change this back into a Coltrisub MCH13/16 by changing the interstage condensate trap, intercooler pipes, and final filter tower assemblies – but if the Seemansub ones are still working, just continue to change the o-rings for 5 years until the hydro expires, then change them all back to Coltrisub.
