In Hyderabad, India, Tirumala Aerated Autoclaved Blocks Private Company has been operating an AAC plant for over twelve years using Teeyer's complete production lines. Running a plant for more than a decade inevitably brings challenges: aging equipment, stagnating output, and missed opportunities in a rapidly growing market.
The plant was producing 900 cubic meters per day—a respectable figure, but well below what the market demanded. Expanding with a completely new line would require massive capital expenditure, extended downtime, and months of disruption. The customer needed a smarter, faster, more economical solution.
The answer? AAC Plant Refurbishment Modernisation — a focused, intelligent upgrade that would transform an aging facility without rebuilding it from the ground up.
Key Takeaways
| Metric | Before Upgrade | After Upgrade | Change |

The Upgrade Project: Scope and Execution
Phase 1: Comprehensive Plant Assessment
The first step in any COMPLEX AAC PLANT RENOVATION is a thorough audit of the existing equipment, control systems, and production bottlenecks. Teeyer's engineering team conducted on‑site diagnostics, analyzing:
Cutting system accuracy and wear levels
Autoclave efficiency and steam utilization
Control system response times and automation gaps
Material handling and waste generation points
This assessment revealed that the plant's core mechanical infrastructure remained sound, but its automation, cutting precision, and process control systems were limiting output and consistency.
Phase 2: Key Equipment Upgrades
Rather than replacing entire production lines, Teeyer targeted the most impactful upgrades:
High‑precision AAC cutting machine upgrading. The existing cutting system was replaced with Teeyer's latest servo‑driven cutting technology, delivering faster cycle times and tighter dimensional tolerances. The result: reduced waste and significantly higher product qualification rates.
Control system modernization. The plant's legacy PLC system was upgraded to a fully integrated DCS (Distributed Control System) based on Siemens PLC hardware, forming the backbone of a true Smart AAC Factory. This upgrade enabled:
Centralized monitoring of all production parameters
Automated recipe adjustments for different product specifications
Real‑time data logging for quality assurance and predictive maintenance
Phase 3: Full AAC Production Line Automation Upgrade
With new hardware in place, Teeyer executed a complete AAC production line automation upgrade, integrating every production stage from raw material batching to finished product packaging. The upgrade included:
Automated formula management for consistent mix design
Servo‑controlled cutting and green cake separation
Intelligent autoclave scheduling and steam recovery
Automated packaging with real‑time quality verification
Results: Measurable Impact in Just Two Months
The upgrade was completed in record time—just two months from start to full operational capacity. By the end of the second month, the plant had increased daily production from 900 cubic meters to 1,400 cubic meters, a 56% improvement.
Beyond raw output, the plant achieved:
Higher product qualification rates. Teeyer's AAC machinery is known for its dimensional accuracy and operational stability, which ensures the highest product qualification rate.
Reduced labor dependency. The automation system uses globally recognized electrical components and features simple yet reliable program logic—this not only reduces labor demand but also enhances production efficiency.
Lower energy consumption. The upgraded DCS systems enabled precise control of steam usage and material flows, cutting waste and reducing energy costs.
How the Upgrade Positions the Plant for the Future
Smart AAC Factory Capabilities
The plant now functions as a truly Smart AAC Factory. Operators can monitor and control production remotely, with the system flagging anomalies before they escalate into stoppages.
Sustainable Building Materials Manufacturing
AAC is inherently a green building material, but this upgrade further reduced the plant's environmental footprint. Energy monitoring tools identify inefficiencies, while reduced waste generation lowers material consumption. The plant now exemplifies sustainable building materials manufacturing at scale—producing more with less.
Remote Diagnosis and Intelligent After-Sales System
Perhaps most valuable for long‑term operation, the upgraded plant is now connected to Teeyer's Remote Diagnosis and Intelligent After-Sales System. Teeyer's whole production line is highly intelligent, capable of remote monitoring and operation. All real‑time data can be recorded, which helps solve production problems quickly, supported by a dedicated team of around 60 engineers with 24‑hour quick response service.
This means that when issues arise—whether a sensor drift, a valve malfunction, or a process deviation—Teeyer's engineers can diagnose the problem remotely, often resolving it before the customer even notices. For urgent needs, the company guarantees rapid spare parts delivery and, when necessary, on‑site technical support.
Customer Testimonial: The Teeyer Difference
Amit Kumar, Director of Tirumala Aerated Autoclaved Blocks Private Company, offered a direct assessment of the partnership:
"Teeyer has always provided us with professional, prompt, and precise service. Their AAC machinery is known for its dimensional accuracy and operational stability, which ensures the highest product qualification rate. Their automation system uses globally recognized electrical components and features simple yet reliable program logic—this not only reduces labor demand but also enhances production efficiency.
Teeyer has installed over forty-five production lines across India and has maintained a leading market share for the past 20 years. Their reputation among both new and long‑standing clients is outstanding—the Teeyer brand is the one you can truly trust."
On the upgrade itself, Kumar added: "Right now, our factory is undergoing a major upgrade. In just two months, we will reach a new daily production capacity of 1,400 cubic meters from 900 cubic meters per day, with automation upgraded to the highest level. We're truly excited about what lies ahead."
His final recommendation: "For anyone considering AAC equipment, my recommendation would be Teeyer — Lead the Future."
FAQ
A: For targeted upgrades like the Indian plant described above, the entire process—from assessment to full operation—can be completed in as little as 2.5 months. More extensive COMPLEX AAC PLANT RENOVATION projects may take three to six months, depending on scope.
