Alfa Laval continues to support legacy separator systems with the EPC 70 Upgraded50, a modern control solution designed to replace older EPC 50 control systems on high-speed separators.
For operators looking to improve reliability, serviceability, and long-term support, upgrading to the EPC 70 platform offers a clear path forward.
What is the EPC 70 Upgraded EPC50?
The EPC 70 Upgraded50 is a retrofit control system designed to replace:
- EPC 50 SU/PU
- EPC 50 SA/PA
It brings updated electronics, improved system integration, and better compatibility with modern monitoring and control requirements, while maintaining compatibility with existing separator installations.
Key Considerations When Upgrading
Upgrading to the EPC 70 system isn’t just a direct swap, it requires identifying key components within your existing setup to ensure the correct parts are selected.
1. Controller Type
The configuration depends on how your system is built:
- Module based systems – SU/PU version required
- Standalone systems – SA/PA version required
2. Separator Type
Your separator model determines whether additional components are needed:
- “S” separators – Require a PCB upgrade for water transducer
- “P” separators – No PCB upgrade required
This is a critical step often overlooked during retrofit planning.
3. Heater Configuration
The heating system plays a major role in the upgrade process.
Electric Heaters
Older EPC 50 systems use a different electrical setup, meaning:
- Additional heater control box or relay kit may be required
- Modifications ensure proper communication with the EPC 70 system
Steam or Thermal Oil Heaters
For systems using SRV (Steam Regulating Valve):
- Actuator replacement is typically required
- In some cases, a full valve and actuator upgrade is necessary
4. System Integration & Communication
Modern EPC 70 systems are designed with improved communication and integration capabilities, making them better suited for:
- Updated vessel automation systems
- Improved diagnostics and monitoring
- Long term service support
Why Upgrade to the EPC 70?
Upgrading to the EPC 70 platform provides several benefits:
- Improved reliability compared to ageing EPC 50 systems
- Better parts availability and long term support
- Enhanced system control and monitoring
- Simplified maintenance and servicing
For many operators, this upgrade is not just about replacement, it’s about future-proofing separator operations.
