Discover the benefits of bringing CCC’s best-in-class turbomachinery controls inside your Honeywell Experion PKS.
WATCH NOWThe Guardian Surge Detection System (SDS) offers SIL-rated surge and overspeed protection for your rotating equipment — all in one device. Protect against damaging surge events in a safety-rated device that is independent of the control system.
Protecting your workforce and rotating assets is critical to your business. With the Guardian SDS, you never have to sacrifice safety for performance. By using a safety system physically separate from the control system, you can protect your equipment not only from physical issues such as sensor or controller failure, but also from devastating cyberattacks. The system’s settings can only be changed with direct access to the unit, offering another layer of protection for your assets.
The Guardian SDS incorporates all Guardian ODS overspeed detection functionality into a single unit while maintaining the capability of a TUV certified SIL-3. Compliant with API-670, API-611 and API-612 standards, the Guardian SDS integrates seamlessly with industry-leading CCC control systems — making it easier than ever to safeguard your rotating assets.
