Save space and costs with Ecomotive® STP Compact
A modern engine room has to contain a lot of equipment, and space is at a premium.
With its high biological capacity, the Ecomotive® STP Compact offers the most space-saving design available. It is available in four sizes, with stainless steel construction.
The elevated tank design allows the Ecomotive® STP Compact to be drained completely. This allows for tank disinfection to support improved system hygiene and crew safety and at the same time reduce the risk of corrosion at the bottom of the treatment unit.
