Recently, our after-sales engineer went to Zhengzhou, Henan, to visit an old customer: Henan Ecological Environment Monitoring Center for product equipment maintenance. Since Henan Ecological Environment Monitoring Center purchased two intelligent integrated distillers from our company in 2014, it has successively added four of the same products, both old and new models. We thank users for their recognition of our company's products, and we also feel a great sense of responsibility. It is equally important to focus on product quality and insist on visiting end users and providing good after-sales service.
