What Ecochlor does

Ecochlor, founded in 2001 and headquartered in North Haven, Connecticut (with a corporate office also referenced in Maynard, MA), is a US-manufacturer of ballast water management systems (BWMS) for commercial shipping. Its proprietary chlorine dioxide (ClO2) treatment technology, marketed under the EcoOne brand across Filterless, Hybrid, and Containerized configurations, treats ballast water across all salinity, pH, temperature, and turbidity conditions without requiring crew adjustments, TRO sensors, or neutralization on discharge. The technology is differentiated by low power consumption (10-20 kW) and high flow rate capacity (up to 16,200 m3/hr approved), and is supported by the proprietary EcoBlue chemical, the only globally-approved chemistry for Ecochlor systems under IMO and USCG Type Approval Certificates.

The company has secured IMO G9 Final Approval (2010), USCG Type Approval (2017 — fifth BWMS approved by USCG and first US-manufactured chemical injection system worldwide), IMO BWMS Code Type Approval (2020), and Class Approvals from ABS, BV, LR, RMRS, DNV, and KR, plus Flag State approvals from Cyprus, Hellenic, and Norway. Ecochlor serves shipowners and operators across tankers, bulk carriers, container ships, and offshore vessels through direct enterprise field sales with regional offices in the Americas, Korea, Japan, Singapore/Hong Kong/China, Greece, Cyprus, and Norway, complemented by authorized installation and service providers. Named customers include Maersk, Scorpio Tankers, Euronav, Bahri, Minerva Marine, Atlantic Container Line, Capital Ship Management, Anglo Eastern, and Maran Tankers.

Ecochlor's revenue model combines one-time BWMS system sales, usage-based EcoBlue chemical resupply coordinated through a dedicated Chemical Operations Team, recurring service and maintenance contracts (twice-yearly ship visits with 98% operational uptime via real-time monitoring), and professional services including DNV-certified crew training. The EcoCare Compliance Guarantee, the only BWMS financial guarantee in the market, underwrites invasive species test failures. As of November 2024, Ecochlor was acquired by ERMA FIRST GROUP and in June 2025 was integrated into ERMA TECH GROUP, a diversified maritime technology platform that also includes ERMA FIRST, EPE Systems Division, RWO, METIS, and Armada Technologies, committing 7% of revenues to R&D across integrated decarbonization, water treatment, and marine equipment solutions.

Products and services

• EcoOne Filterless BWMS Ballast Water Management System that treats water using a single-step process of disinfection with chlorine dioxide (ClO2) alone. Operates in all marine and brackish waters (>1 PSU) with no restrictions on temperature or turbidity, using only 10-20 kW of power even at high flow rates. For shipowners and operators globally.
• EcoOne Hybrid BWMS Ballast Water Management System offering dual modes of operation (filtration with ClO2, or ClO2 alone). Provides flexibility for unrestricted global operation with the convenience of a no-filter option when water conditions permit. For shipowners operating across varied water conditions and trade routes.
• EcoOne Container BWMS Containerized ballast water management system using a single unit to serve four quadrants or substations with one-way, small diameter piping for offshore installations. No filter required, with gravity ballasting possible. Designed for offshore support vessels, tug barges, semi-submersible rigs, and multi-purpose vessels.
• EcoBlue Chlorine Dioxide Treatment Chemical Proprietary chlorine dioxide solution used in Ecochlor BWMS, the only chemical globally approved for use in Ecochlor systems under IMO and USCG Type Approval Certificates. Supplied as ongoing chemical resupply coordinated by Ecochlor's Chemical Operations Team.
