Advantage of ECS
Powerful disinfection system, Low power consumption ◀ 12.8K Product / Chemical tanker
meets higher standards (California) - ECS uses maximum 3.4 kw to treat 100m3/h of 8PSU sea
- ECS meets California’s standards (SB497) which is 1000 water (7.3kw for 100m3/h of 3PSU sea water).
times stricter than IMO’s. - No need for an extra generator.

ECS can be customized to suit your needs

- Neither of organism grew back in 30 days according
to KORAD re-growth test nor 50 days according to Low operation cost
Techcross R&D Center. - To operate ECS, only a little fuel cost is needed.
- The Electrode Module as key components has an expected
Treating once at ballasting life of 8,000 to 10,000 hours and used for nearly 20 years.
- Residual chlorine in treated water keeps water clean,
thus retreatment at deballasting is not required.
Easy to install and maintenance
- Easy to operate and save so much expense.
- Modular type system.
No filtration required - Easy replacement by ship crews.
- ECS complies with IMO standards without filtration
which causes flow interruption. Automatic operation
- Maximum flow loss is only 0.2 Bar. - Automatic operation is available by Window-based HMI.
