Retrofits
Why considering a retrofit?
- Your DCS system is no longer maintained. Moreover, as it ages, its compatibility with new products is compromised.
- Cybersecurity is not up to date. Old cybersecurity systems were not design to resist against modern attacks. As systems become more connected, a stronger cybersecurity design is mandatory.
- Some spare parts might no longer be available. Critical components of your DCS may not be available in the market anymore, which represent a threat to your production process.
- Expertise is less available today. If your DCS relies on obsolete technology, it may be difficult to find experts who can help maintain it in operational conditions
IEPC’s commitments for a successful retrofit
- Risk management and adaptability. We only provide robust, proven and tested solutions which adapt to your production needs and conditions (rhythm, quality, continuity).
- A fast, optimized and secure retrofit. The modernization of your DCS should not be a threat to your process. IEPC ensures that the modernization of the DCS is done as fast as possible, always maintaining the security and the continuity of critical systems.
- A clear and measurable commitment throughout the intervention. IEPC commits with you until the end of the retrofit, and set clear and measurable milestones to help you control the retrofit process.
- Shared decisions and transparent communication. IEPC gives you complete transparency through regular reporting, shared decisions and performance indicators. You keep total control of the retrofit process.
