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 comes in four different sizes in both stainless steel and black steel execution.

Elevated on legs, the STP tanks can be drained completely. This allows for tank disinfection to support improved system hygiene and crew safety and at the same time prevent corrosion attacks on the bottom of the STP (black steel execution).
