Customer background

It serves as the core manufacturing and R&D base for a global leading electronic paper company in China, responsible for the key production of electronic paper modules and display materials. With the rapid growth of large-format electronic paper and smart display applications, continuous factory expansion, and the demand for high-cleanliness processes and environmental control, energy consumption has greatly increased. Under global customers' requirements for low-carbon supply chains and ESG disclosure, how to reduce energy consumption while ensuring product yield has become a key operational issue.

Challenges and pain points

Core process "no room for deviation by the second"

E-paper production demands extremely high temperature, humidity, and cleanliness. If air conditioning and cooling systems reduce power to save energy, it will directly threaten product yield, creating a tug-of-war between "energy saving and yield."

The 'black box effect' of electricity consumption

Electricity in the plant accounts for 70–80% of the area, but the energy consumption of process equipment and facility facilities is intertwined, making it difficult for traditional manual meter reading to identify the true "hidden energy-consuming monster."

Energy-saving investment recovery and operating cost pressures

High-efficiency equipment, green electricity, and energy-saving retrofits require long-term investment, and companies must balance energy-saving benefits with operating costs.

Compliance and ESG pressures of 'falling behind if you don't upgrade.'

It must align with the Group's carbon reduction targets and international client requirements (RE100, Carbon Disclosure), and energy and carbon data must be time-sensitive and traceable.

Learn about our products and platforms

Visible: Energy Diagnostics and Process Energy Consumption Structure Establishment (Consultant)

In a multi-system factory operation with complex energy consumption sources, JOSUN conducts energy inventory and flow analysis to break down the electricity usage structure of air conditioning, air compressors, and process equipment, establishing energy KPIs and management indicators.
👉 This shifts energy from being "distributed and invisible" to "visualized management," effectively reducing unnecessary energy consumption

Manage: Energy Dynamic Optimization under Process Conditions (Platform)

Without compromising process stability, JOSUN has introduced an energy management platform (iFMCS/IWA) that integrates different energy flow directions, including process, fire protection/systems, and environment (including chilled water systems/air conditioning systems/process cooling water systems/lighting systems), and dynamically adjusts according to production line loads (variable air volume/variable water volume/intelligent control).
👉 Achieving 'Stable Process × Energy-Saving Optimization'

Achieved: Optimization of high-energy-consuming equipment and energy recovery (engineering)

Systematic optimization of key energy-consuming equipment
Magnetic Levitation Ice Water Main Unit (High-Efficiency Cooling)
