In today’s maritime industry, efficiency and reliability are no longer optional—they are essential. With increasing demands for sustainability, reduced downtime, and cost-effective operations, advanced control systems like EPC50 and EPC400 have become game-changers. Both systems are designed to optimize separator performance, ensuring vessels run smoothly while meeting strict environmental regulations. But what sets them apart, and how can ship operators choose the right solution?
What Are EPC50 and EPC400?
The EPC50 and EPC400 are electronic process control units developed for marine separators. Their primary role is to manage separation processes such as fuel, lube oil, and bilge water treatment. By automating key functions, they minimize human error, extend equipment life, and improve energy efficiency.
- EPC50 – A proven, robust system widely used across fleets for decades. Known for its simplicity, durability, and ease of integration.
- EPC400 – The next-generation upgrade, delivering higher efficiency, advanced monitoring, and connectivity features aligned with modern digital shipping needs.
EPC50: Trusted Reliability
- Simple design and operation
- Proven track record across global fleets
- Low maintenance with easy spare part availability
- Best for vessels seeking cost-effective solutions without complex digital requirements
EPC400: Smart Innovation
- Enhanced process optimization and automation
- Real-time monitoring with advanced sensors
- Integration with ship digital systems (IoT-ready)
- Lower energy consumption and optimized separation cycles
- Designed for future compliance with IMO regulations
Benefits for Ship Operators

Reduced Operating Costs
Both EPC50 and EPC400 reduce energy waste and minimize downtime, but EPC400 offers greater savings due to its smart cycle optimization.
Enhanced Compliance
Stricter IMO and MARPOL regulations demand higher operational standards. The EPC400, with its advanced monitoring, ensures vessels stay compliant with ease.
Flexibility in Choice
Operators can choose EPC50 when seeking affordability and proven reliability, or EPC400 when looking to invest in future-ready efficiency and digitalization.
Which One Should You Choose?
Choose EPC50 if your fleet values simplicity, lower upfront cost, and tried-and-tested reliability.
Choose EPC400 if your operations demand advanced efficiency, digital integration, and long-term savings
Conclusion
The choice between EPC50 and EPC400 depends on the vessel’s operational goals. While EPC50 remains a reliable, budget-friendly option, EPC400 stands out as a forward-looking solution for shipping companies aiming to embrace digital transformation and sustainability.
