The fan on site of a northern customer was damaged, which seriously affected the normal operation and production of the company. On September 28, we consulted our company for help, signed the contract on September 29, delivered the goods on September 30, arrived at the site on October 5 (National Day logistics was delayed for one day), and on October 5, during the National Day holiday, our debugging personnel worked overtime late at night to complete the on-site debugging and successfully started the machine!!! This is our service attitude, our work efficiency!! Thank you very much for your support and trust!! Thank you for your hard work!
