Application field

The GRAEFF intelligent controller series, with its precision, reliability and flexibility, is widely used in the following industries and related fields:

Extrusion machinery field

Extrusion machinery is a key equipment for the molding of materials such as plastics and rubber. Even minor fluctuations in temperature and pressure during the production process can lead to deviations in product size and performance. The GRAEFF G100 model is suitable for extrusion applications. During the extrusion process, it quickly captures and responds to the dynamic changes in temperature and pressure, avoiding overshoot and undershoot, and reducing the defect rate from the source. Meanwhile, its energy-saving design can reduce production energy consumption and help enterprises cut costs and increase efficiency.

The field of food machinery

Food production has strict requirements for temperature accuracy and production continuity, and must strictly follow food safety standards. The temperature control accuracy of GRAEFF's intelligent controller can ensure the stability of the temperature during the heating and cooling processes of food. High-quality components are adopted to achieve low power consumption and low-temperature drift, saving energy while reducing production costs. Its anti-interference performance meets the strict industrial electromagnetic compatibility requirements, ensuring the continuous and safe production of food and safeguarding "food safety on the tip of the tongue".

The field of industrial intelligence

The intelligent transformation of industry needs to be driven by data to achieve intelligent control and remote management of equipment. The self-tuning function of GRAEFF's intelligent controller can automatically optimize parameters based on the controlled object, eliminating the need for repeated manual debugging. It has a data acquisition function and can capture real-time data such as temperature, pressure and liquid level, providing support for production decisions.

The petrochemical industry

Petrochemical production often operates under complex conditions of high temperature, high pressure and strong electromagnetic interference, which places extremely high demands on the response speed and anti-interference capability of control equipment. The GRAEFF intelligent controller can respond quickly to sudden changes in temperature and pressure, avoiding safety accidents caused by control lag. Its anti-interference performance enables it to operate stably in a strong electromagnetic environment. Single/dual configurable alarm functions monitor key parameters in real time and issue timely warnings when abnormalities occur to ensure production safety.

The field of energy and environment

In the energy industry: At power stations, controllers monitor the operational status to ensure a stable and safe power supply. In oil and gas pipelines, monitor the pressure and temperature inside the pipelines to prevent leakage accidents.

Environmental monitoring: Environmental monitoring stations use it to monitor air pressure and temperature, assisting in the assessment of air quality and climate change. Water treatment plants monitor water pressure and water temperature through it to ensure effective management of water resources.

The field of HVAC and smart home

Hvac system: The controller regulates the indoor temperature and humidity to create a comfortable environment. Optimize temperature and pressure control, improve energy utilization efficiency, and reduce operating costs.

Smart home: Monitor changes in pressure and temperature in the home environment, and promptly detect gas leakage and fire risks. Automatically regulate indoor temperature and humidity to enhance living comfort and save energy.

Laboratory research field

In chemical and biological experiments, the precise control of experimental conditions is the key to ensuring the accuracy and repeatability of results. The GRAEFF intelligent controller can precisely control experimental conditions such as pressure and temperature. It also has a data recording function to store data during the experiment, facilitating subsequent analysis and research.

Summary

The GRAEFF intelligent controller series, with "precise control, multi-scenario adaptation, and high reliability" as its core advantages, has built a complete industrial control solution covering from basic display to precise regulation. From ensuring the production accuracy of extrusion machinery and food machinery to the safe and stable operation of petrochemicals, energy and the environment, and then to the innovation-driven development of industrial intelligence and laboratory research, its in-depth application in multiple fields is not only the core driving force of industrial automation, but also a key technical support for promoting cost reduction, efficiency improvement and digital transformation in various industries. In the future, as the demand for industrial intelligence continues to upgrade, GRAEFF intelligent controllers will continue to take technological innovation as the engine, release the value of precise control in broader industrial scenarios, and inject strong impetus into the development of global industrial automation.
