Why is it necessary to accelerate fan energy-saving replacement at this stage?

The core direction of the “Implementation Plan for High-Quality Development of Energy-Efficient Equipment (2026–2028)” is to build a standardized and systematic industrial energy-saving framework. From both technological breakthroughs and system-level energy efficiency, the plan sets a clear pathway for the upgrading of industrial fans:

The column clearly defines the core technological directions for energy-efficient fan development, focusing on key areas such as high-efficiency wide-load triturboimpellers, low-cost permanent magnet materials, and low-loss transmission structures. It also identifies permanent magnet variable frequency speed control and permanent magnet synchronous direct drive as key technologies for promotion, and encourages priority adoption of advanced solutions listed in the Recommended Catalogue of Energy-Saving and Carbon-Reduction Technologies and Equipment.

At the same time, the plan further emphasizes system-level energy optimization as a key focus, promoting precise matching between energy-saving equipment and operating loads and conditions. It encourages coordinated optimization across interconnected systems and integrated intelligent operation and maintenance management, driving the transformation from single-equipment retrofits to full-process system-wide energy efficiency improvement.

This means that fan energy efficiency upgrades are no longer a matter of voluntary enterprise choice, but an inevitable measure under policy-driven technical standards, mandatory retrofitting of existing capacity, and full-process energy efficiency supervision. Only energy-saving fan solutions that align with the prescribed policy and technological roadmap can truly achieve compliance, cost reduction, and long-term performance.

What should be prioritized when selecting energy-efficient fans?

▶Aerodynamic optimization of impellers and application of triturbotechnology

The policy document clearly states the need to continuously upgrade the aerodynamic design of energy-efficient fan impellers and optimize internal flow channel structures. By reducing airflow losses, overall operating efficiency should be improved. It also identifies the high-efficiency wide-loadtriturboimpelleras a key core component for industry-focused technological breakthroughs.

As the core component of a fan, the impeller directly determines overall energy consumption levels. Traditional impeller designs have clear structural limitations, leading to airflow instability and significant vortex losses. They can only operate under fixed conditions and are unable to meet current energy efficiency upgrade standards.

Leveraging mature triturboaerodynamic technology, NorthGlass triturbo fans achieve integrated optimization of impeller and flow channel design. Through simulation-based modeling of full-domain airflow conditions, the system effectively reduces unnecessary internal losses, enabling stable and highly efficient performance throughout long-term operation.

▶Permanent Magnet Motor & Direct-Drive Low-Loss Structural Layout

In the energy-efficient equipment technology upgrade roadmap, the state prioritizes the R&D and application of permanent magnet materials, while actively promoting technologies such as permanent magnet synchronous direct drive and variable frequency speed control. The core objective is to reduce energy losses caused by mechanical transmission systems.

Traditional fans rely on transmission components such as belts and gearboxes, resulting in complex structures, significant power transmission losses, and consistently high maintenance and servicing costs over the long term.

In line with evolving policy trends, NorthGlass adopts a high-efficiency permanent magnet direct-drive solution to simplify the transmission structure and reduce intermediate power losses. Leveraging its mature equipment adaptation experience and existing plant operating conditions, NorthGlass is able to provide customized power upgrade solutions for enterprises, ensuring both operational stability and long-term energy efficiency.

▶Wide-range high-efficiency operation, adaptable to complex and variable working conditions

Industrial production is typically characterized by significant load fluctuations and frequent changes in operating conditions. The policy also emphasizes that energy-efficient equipment must possess stronger scenario adaptability, eliminating inefficient “oversized equipment for small loads” operation modes and preventing excessive energy consumption at the source.

Most conventional fans only meet performance standards under rated operating conditions. Once production loads fluctuate or are adjusted, operating efficiency drops significantly, resulting in a substantial reduction in actual energy-saving performance.

NorthGlass triturbo fans expand the high-efficiency operating range and are designed to adapt to dynamic changes in airflow and pressure across production scenarios. Even under frequent operating condition fluctuations, they maintain stable and efficient performance, fully meeting the continuous and increasingly complex production requirements of modern factories.

▶System-level coordinated optimization for integrated energy-saving retrofit solutions

The new energy-saving policy no longer focuses solely on efficiency improvements of individual equipment, but places greater emphasis on the coordinated optimization of entire energy systems. It promotes integrated control of equipment, adaptive adjustment of pipeline networks, and drives the transition from single-unit energy efficiency improvements to system-wide energy optimization across the entire plant.

To maximize the value of retrofitting, factors such as pipeline layout, equipment matching, and operational management all ultimately influence the final energy-saving performance.

Unlike simple equipment supply, NorthGlass also provides comprehensive plant-wide energy-saving diagnostic services. By on-site analysis of existing fan operating data, pipeline layout, and energy consumption inefficiencies, and in combination with policy standards and actual production conditions, NorthGlass delivers tailored, integrated solutions for fan retrofit and system optimization.Through supporting measures such as variable frequency control and intelligent operation and maintenance management platforms, NorthGlass helps enterprises streamline the entire energy-saving retrofit process, achieving systematic cost reduction and efficiency improvement.

Not Just Equipment Upgrades, but a Transformation in Energy Efficiency

The period from 2026 to 2028 marks a critical phase for the standardization of industrial energy-efficient equipment technologies and large-scale retrofit of existing capacity.Replacing a fanis not merely about upgrading a set of equipment, but a practical measure to optimize energy usage, control operating costs, and comply with policy requirements.

Against the backdrop of the current momentum toward energy conservation and carbon reduction, the phasing out and upgrading of old, high-energy-consuming fans has become an inevitable trend. Through the iteration of high-efficiency energy-saving fans and new technologies such as permanent magnet drive, enterprises can effectively reduce overall plant energy consumption, lower long-term electricity costs, and steadily improve equipment operational stability and production efficiency.At the same time, this transformation helps companies align with dual-carbon regulatory requirements, strengthen the foundation of green manufacturing, and achieve multiple value outcomes including energy saving, cost reduction, efficiency improvement, and low-carbon development, thereby building a solid green foundation for long-term and stable business operations.
