Kazakhstan is the largest economy among the five Central Asian countries, and its economy has developed rapidly in recent years. The autoclaved aerated concrete (AAC) industry in Kazakhstan is experiencing a period of rapid growth, with a supply shortage of AAC products. Although there are many AAC plants in Kazakhstan, most of the AAC plants are characterized by low production capacity, low automation, and low product yield, which results in failure to meet the increasing market autoclaved aerated concrete (AAC) demand and quality requirements.
SENSATA Group is a well-known real estate developer in Kazakhstan. To ensure the quality and progress of their projects, they decided to invest in establishing their own AAC plant. After multiple site inspections and associated studies, Teeyer Intelligent successfully signed a contract with Sensata Group in 2023 to jointly build the UNITON project. Located in Astana, this project will produce 200,000 cubic meters of autoclaved aerated concrete (AAC) blocks annually and is expected to begin AAC production smoothly in June 2024, setting a new benchmark for the local autoclaved aerated concrete industry.

A fully customized AAC plant
The UNITON project is the most advanced and highest-standard autoclaved aerated concrete production line established in Kazakhstan in the past three years. It takes into full consideration the local market characteristics, climatic features, and building design standards, and adopts Teeyer's latest 4.8 × 1.2m AAC production line model. As Astana is located in northern Kazakhstan, the long winter season limits the time available for large-scale outdoor construction, resulting in significant seasonal variations in autoclaved aerated concrete (AAC) product sales. Teeyer's 4.8 × 1.2m AAC production line model can adapt to a daily production capacity ranging from 300 to 1000 cubic meters, allowing users to flexibly adjust production capacity. When the peak season arrives and autoclaved aerated concrete production volume rapidly increases, the average energy consumption and labor requirements of the entire plant will not significantly rise.This is due to the flexibility of Teeyer's AAC production rhythm and the precise control of automation. Under stable and reliable conditions, the 4.8 × 1.2m AAC production line model can achieve a continuous production rhythm of 2 minutes per mould, without affecting the quality of the products or increasing equipment wear. This provides users with ample capacity for production increases, making production management more flexible and controllable.

All-round one-step service in establishing autoclaved aerated concrete (AAC) production line.
Teeyer Intelligent was deeply involved in the entire construction process of the UNITON AAC plant project, providing a full range of one-stop AAC production line services, including preliminary AAC plant planning, process design, civil construction guidance, AAC equipment installation, automation debugging, process formulation support, and autoclaved aerated concrete trial production. It took only 11 months from signing the contract to producing the first product, making it one of the shortest construction periods for AAC production lines in the Central Asian region. Teeyer not only has a strong AAC equipment R&D team but also boasts professional design, AAC project management, after-sales service teams, as well as an experienced AAC plant production and management team. During the construction of the UNITON AAC project, Teeyer dispatched nearly 20 support personnel to provide strong support and assistance to the user.

Considering the general lack of professional electrical engineers and maintenance workers in Kazakhstan's AAC plants, the UNITON project's automation design framework utilizes industrial Ethernet communication, with Profinet combined with a human-machine interface to form a three-level control structure of central control, regional centralized control, and single-machine control, enabling information exchange and data sharing. Siemens S7-1500+ET200 system equipment is used as the main hardware, employing advanced technologies such as system redundancy and digital computing. This design features low system failure rates, stable operation, and easy maintenance. The three-level architecture complements each other, ensuring that the entire AAC production line does not shut down due to control system failures.
Accounting for the local raw material conditions in Kazakhstan, Teeyer’s electrical engineers developed a process control system tailored for Kazakhstan, using advanced algorithms for precise mix design calculations and material process control. Through a simple automated operation process, it meets the requirements of
autoclaved aerated concrete process data under different environmental conditions and achieves precise control of servo systems for cutting, conveying, autoclaving, and packaging equipment, ensuring AAC product quality and improving AAC production efficiency.

Through multi-logic programming, such as predictive programming, real-time feedback, position correction, feedforward control, and optimal control, the control system has been extensively upgraded across multiple production lines. High-precision sensors are widely used, and technologies such as background suppression, multi-detection, signal authenticity discrimination, and shielding are applied. These technologies consider and adapt physical production variables such as equipment position, displacement, liquid level, and temperature, achieving automatic, intelligent, and energy-saving control of the AAC production process.
The human-machine interface is designed with process graphics, motion status, real-time data, trend curves, data reports, alarm records, and parameter settings, focusing on practicality, ease of use, and data visualization. This ensures that users can adjust equipment position, speed, and other parameters according to production needs and process requirements, as well as timely monitor the real-time status of on-site equipment and quickly find the required information and functions. Teeyer provides clear operation instructions and processes, enabling users to smoothly operate the systems and execute successful troubleshooting.
Teeyer Intelligent has been deeply involved in the autoclaved aerated concrete industry for over 30 years. During its internationalization process, it has always adhered to a "customer-centered" business philosophy, adapting to local conditions, and striving for localization in research and development, design, manufacturing, and service based on local market characteristics, product features, and customers' individual needs. At the same time, Teeyer will continue to support users and industry associations in various regions to promote the use of autoclaved aerated concrete products, enabling more countries and regions to use lightweight, energy-saving, and environmentally friendly AAC products, thereby driving the transformation and upgrading of the local building materials industry.
