In semiconductor, new energy and other high-energy-consuming factories, HVAC and compressed air systems are the true 'power heart', typically accounting for over 30% of total plant energy consumption. But this 'heart' often operates inefficiently. Core equipment like chillers, air compressors, and pumps mostly rely on fixed operation strategies or manual adjustments based on experienced workers' intuition, leading to common 'big horse pulling small cart' rough operations and wasted electricity on redundant operations.

Moreover, parameter settings tend to be conservative, failing to adjust with weather changes or production pace, so energy efficiency never reaches optimal levels. Worse still, chiller stations, air compressor stations, and circulating water systems operate independently without coordination, and local adjustments sometimes lower overall efficiency.

In essence, traditional management is reactive and siloed, making public utility systems a tough hurdle in factory cost reduction, efficiency improvement, and green transformation.

Public Utility Intelligent Control Agent: Paradigm upgrade from extensive to precise

Against this backdrop, Gtrontec Public Utility Intelligent Control Agent was born. It's not a retrofit of single equipment but a 'system-level energy efficiency optimization engine' integrating deep industry knowledge and data intelligence.

The core value of the solution is to help public utility systems achieve three upgrades:

 

From extensive operation to precise supply: real-time optimization algorithm dynamically matches the best working point of equipment, truly 'supplying as needed'.

From post-event statistics to prediction-driven: based on load forecasting and energy efficiency simulation, adjust operation strategies in advance, turning passive response into active intervention.

From single-point optimization to global coordination: break down barriers between subsystems, achieving coordinated scheduling of chillers, pumps, cooling towers, air compressors, and other equipment groups, optimizing load distribution.

By deploying modules for real-time energy efficiency monitoring, online simulation, and intelligent control, we enable the factory's power system to operate precisely and efficiently every time, completely eliminating 'ineffective energy consumption'.

A leading semiconductor company implementation, tangible energy-saving benefitsA top domestic semiconductor manufacturing company faced high energy consumption in its public utility system: the plant's chiller station and compressed air system consumed enormous energy, long relying on manual experience for adjustments, with conservative operation strategies and repeated setbacks in energy efficiency improvement, resulting in annual energy costs of tens of millions of RMB. To meet the group's requirements for green transformation, cost reduction, and efficiency improvement, the company introduced the Public Utility Intelligent Control Agent. Gtrontec conducted a comprehensive intelligent energy-saving retrofit of the chiller station water system, improved the sensor network, and deeply integrated with the plant's original factory monitoring system, achieving end-to-end transparent management of key data. Leveraging built-in optimization algorithms and industry mechanism models, the system globally optimizes equipment like chillers, pumps, and cooling towers, achieving automatic control without frequent manual intervention.

Building on the customer's solid foundation of high-level energy management, breaking through the existing energy-saving bottleneck, the system achieved about 9% system energy efficiency improvement, with annual energy-saving benefits exceeding 4 million RMB. Meanwhile, intelligent monitoring and automated inspections greatly improved O&M efficiency, successfully achieving centralized management and reduced staffing. This retrofit not only saved real money for the company but also solidified the foundation for refined management, providing solid practical support for certifications like green factory and energy efficiency leader.

Next issue, we will present the EHS Intelligent Environment, Health and Safety Agent solution, see how to integrate scattered EHS risk points into a unified visual management platform, shifting from passive compliance to active prevention.
