Energy Resource Management

Innolux's energy resource management, in addition to daily inspection of electricity consumption and identification of opportunities to reduce energy consumption, save energy through measures such as operation adjustment, control adjustment, equipment update and system integration, in line with national energy laws and international energy conservation and carbon reduction trends Each plant plans to improve the utilization rate of energy resources every year. Through the operation of the plant technical committee and its cross-plant platforms for water, electricity, gasification, and air conditioning, it implements the effective use of energy resources and the recycling of resources. The enterprise's competitiveness is a win-win operation cost and environmental protection.
 

ISO 50001 Energy Management System Implementation

In response to the development trend of global sustainable energy management, INNOLUX has established the energy management system and mechanism in accordance with ISO 50001:2018 standard in 2019, and established an energy management system in G6 and G8.5 TFT-LCD FAB as model pilot plants, and obtained the third-party ISO 50001 certificate from BSI British Standards Association in May, 2020.
 
The PCDA of ISO 50001 Energy Management System

To fully demonstrate the importance of energy management, INNOLUX has set up an energy management technical committee as the decision supervision unit who issued energy policies, built energy object and targets, established energy performance indicators, developed and promoted energy action plans to achieve continuous improvement of energy performance based on P-D-C-A continual improvement framework.
INNOLUX will extend ISO 50001 from two model pilot FABs to all TFT-LCD process FABs and the energy management will be integrated with the INNOLUX ESH culture to make contribution to sustainable development in environmental field and mitigation of climate change, and realize social responsibility.
 
2019 Major Energy Conservation Saving Projects
●Replace the pure water supply Canned Motor pump to a centrifugal pump. (Analysis of the operating efficiency of Canned Pump is only 60% of centrifugal pumps).
●CVD heat preservation and energy saving, due to the analysis that the newly purchased low temperature process CVD new machine is quite different from the old machine, and improve Chamber's heat preservation measures.
●The fan of CDA cooling water tower is changed to frequency conversion.
●Replacement of MAU wet-membrane plate: The wet-membrane plate of the external air conditioning box will increase with the use time, and the growth of microorganisms will affect the pressure loss and humidification efficiency, so it is replaced with a new product with high efficiency.
●CDA Final Filter pressure loss transformation: evaluate the inlet and outlet flange face space, increase the final filter barrel diameter and replace it with a new large flow low pressure loss filter.
