Red wine mash tank with internal plunger FD-IT

The rest is in the tank

The mounting of the pneumatic cylinder on the tank top requires more space. In low-ceilinged cellar rooms this can some­times pose a problem and often there is no possibility to use such tank systems.

Speidel’s innovative »internal plunger« solves this problem once and for all. Speidel’s well-tried immersion system via pneumatics is an integral part of the tank’s interior, thus allowing to reduce the tank's height considerably. At a comparable total height of the tank systems the reduction of height allows 50 % more capacity.

Due to the new level adjustment of the immersion wings the minimum filling amount can be reduced up to 40 % of mash tank’s nominal volume. This way even smaller amounts can be processed.
