Xinjiang Oriental Hope is a core long-term cooperative customer of Hope Deepblue. In the past, it has always given priority to cooperating with Hope Deepblue in multiple lithium bromide unit projects. As a national key high-tech enterprise and an industry-recognized "waste heat utilization expert", Hope Deepblue has won high recognition and full trust from Xinjiang Oriental Hope through in-depth cooperation in previous projects, relying on its excellent product quality of lithium bromide units, improved after-sales service system and rich service experience in the industrial field. This year, to further increase polysilicon production capacity, Xinjiang Oriental Hope once again invited Hope Deepblue to provide professional maintenance services for the in-service steam-type lithium bromide units in its Zhundong Polysilicon Plant, helping to promote its stable production.

On the way to Xinjiang, the technical service team of Hope Deepblue in the northwest region suddenly received an urgent feedback from the on-site of Xinjiang Oriental Hope: the unit had a sudden failure and lost refrigeration function, which directly threatened the normal operation of polysilicon production. Adhering to the service commitment of "responding within 2 hours for any unit failure and maintenance request", Hope Deepblue quickly activated the emergency response mechanism and initially judged the cause of the failure based on years of experience in lithium bromide unit maintenance. To minimize the impact of the failure on production, the company immediately set up a special online communication group and arranged experienced senior service engineers to provide full-process video practical guidance to on-site staff, quickly implemented emergency treatment measures, and successfully temporarily restored the unit operation, gaining valuable time for subsequent on-site maintenance.

After the service team arrived at the site, with the close coordination of the company's business, technology, materials, construction and other departments, they quickly carried out a comprehensive investigation, accurately located the core of the failure, scientifically formulated a detailed maintenance plan, and efficiently completed the contract signing. Relying on Hope Deepblue's improved spare parts supply system and professional technical strength, the maintenance team efficiently promoted the fault repair work. At present, all fault points of Unit 3 have been successfully repaired, and the unit is operating stably and efficiently, which has successfully solved the user's urgent needs and comprehensively ensured the continuity of polysilicon production of Xinjiang Oriental Hope.

The efficient emergency response and professional maintenance services have made Xinjiang Oriental Hope full of praise for Hope Deepblue's service efficiency and technical strength. It put forward the intention of in-depth cooperation on the spot and decided to entrust all lithium bromide units with obvious attenuation in operational performance in the plant to Hope Deepblue's team for maintenance. Considering the continuity requirements of polysilicon production, to avoid the impact of large-scale shutdown on production progress, Hope Deepblue's service engineers went deep into the production workshop, carefully inspected the actual operation status of each unit, comprehensively analyzed the causes of unit performance attenuation, and combined with the user's urgent needs, jointly agreed with Xinjiang Oriental Hope to adopt a phased maintenance mode, carrying out maintenance work on each unit according to the priority of unit faults, so as to achieve both maintenance and production.

Hope Deepblue's scientific, prudent and meticulous work attitude and professional and efficient service capabilities have once again been highly recognized by the user. At present, Xinjiang Oriental Hope has officially approved the maintenance project approval of Unit 8 and will continue to entrust Hope Deepblue to provide full-process maintenance services for its lithium bromide units, working together to build a solid production guarantee line. In the future, Hope Deepblue will continue to adhere to the service concept of "customer first", give play to its advantages in R&D and service in the field of lithium bromide technology, and with the full-life cycle service concept, provide more refined and professional equipment maintenance and system solutions for users in various industries, protect the stable production of users with professionalism and efficiency, interpret the corporate philosophy of "Serving the Country through Industry, Striving for the First Forever" with strength, and continuously convey brand value and trust.
