BALLAST TREATMENT SIPLIFIED
MADE SIMPLE
oneTANK is a simple, low-cost ballast water treatment system.
Developed for the tanker aftpeak tank, perfect for superyachts and workboats with power limitations.
IMO AND USCG TYPE APPROVED
oneTANK is type approved by the US Coast Guard and Norway in accordance with the rigorous standards of the US Code of Federal Regulations and the IMO revised Ballast Water Management Code. These approvals ensure compliance with regulations worldwide, including the United States.


WHY oneTANK
The small size, few connections, and class approved instructions means installation and commissioning are simple.
The oneTANK footprint is just two-by-two feet, eliminating or minimizing relocation of other equipment.
Needs just one single phase 15 Amp/120V or 7.5Amp/240V electrical feed, barely more than a household oven.
A small diameter pipe connects your ballast line to oneTANK and the in-tank mixing nozzles, minimizing install time and expenses.
Pulls a small amount of ballast from the tank, through oneTANK, out mixing nozzles. Use an existing pump, or we can provide a new one.
Fully automatic lets mariners focus on other tasks. No filters to clean. In-tank treatment means you treat when you want to, avoiding busy times.
