With our Service Box Pro for anaerobic digesters and feedstock storage tanks with concrete or membrane roofs, operation of mixers is child’s play. Rotating the mixer to the left and right or adjusting the height is done from outside the tank within just a few minutes. General mixer maintenance can be completed on the Service Box platform thanks to the removable floor panel without lowering the level of the tank or even opening the membrane roof. That saves money and, of course, valuable time!

In addition, use of the Service Box Pro patented gas lock seal enables safe digester maintenance with low methane emissions.
General mixer maintenance can be completed on the Service Box Pro platform thanks to the removable floor panel. For larger maintenance tasks or in case of replacement, mixers can be completely removed by simply loosening clamping bolts. All of this is possible without lowering the level of the tank or even opening the membrane roof. As a result, there is minimal or no impact on the biological process. That saves money and, of course, valuable time.
For plant operators, Service Boxes do not only mean a significant improvement of plant operating times, but also a huge plus in terms of safety.
