Emergency Shutdown Systems

Identifying Critical Conditions Early

Emergency Shutdown Systems continuously monitor safety-related process conditions and identify situations that require protective action. When predefined operating limits are exceeded, the system initiates the required shutdown response.

By recognising critical situations at an early stage, plants can reduce risk exposure and support safe and reliable operations before incidents escalate.

Bringing the Plant to a Safe State

When hazardous conditions occur, Emergency Shutdown Systems automatically execute predefined shutdown actions to place equipment and processes in a safe state. The shutdown response is designed according to the specific requirements of the application.

This helps protect people, the environment and critical production assets while limiting the consequences of potentially dangerous situations.

Minimising the Impact of Hazardous Events

An effective Emergency Shutdown System helps reduce the potential consequences of abnormal operating conditions and process upsets. Safety functions are executed automatically when required to support the overall protection strategy of the facility.

By limiting the impact of hazardous situations, operators can improve plant safety and maintain greater confidence in day-to-day operations.

The Right Solution for Every ESD Application

Different applications require different levels of performance, scalability and flexibility. HIMA offers a portfolio of safety controllers that can be used for emergency shutdown functions across a wide range of industrial environments.

Whether using HIMax, HIQuad X, HIMatrix or Planar4, organisations benefit from proven technology designed to support safe plant operation and reliable protection in critical situations.

HIMax is a high-performance, uninterrupted safety controller for challenging applications. The SIL 3 platform protects your safety-critical production processes and makes your plants more profitable. One of the potential applications for HIMax is as an emergency shut down system for protecting depolymerization reactors. Here, HIMax can be used for all applications up to SIL 4 (CENELEC).

HIMatrix is the safety platform for networked and time-critical applications. The systems can be used as standalone devices or in distributed applications. They are specifically developed for applications with few inputs and outputs per location. For example, they are used in the rail industry as emergency shut down systems. Here, HIMatrix can be used for all applications up to SIL 4 (CENELEC).
