Suzhou Hengda Purification Equipment Co., Ltd inspects raw materials and facilities before the production of hydrogen production unit begins. After product samples are provided, we verify that the suppliers have ordered the correct raw materials. We also randomly select and inspect a sample of partially produced products for potential defects. We improve product quality and minimize the chance of defects during production.

For Zhongsu Hengda, it is important to gain access to international markets through online marketing. Since inception, we have been longing for being an international brand. To achieve that, we have built our own website and always post our updated information on our social media. Many customers give their comments like 'We love your products. They are perfect in their performance and can be used for a long time'. Some customers repurchase our products several times and many of them choose to be our long-term cooperative partners.

These years witnessed the success of Hengda Purification in providing on-time services for all products. Among these services, customization for hydrogen production unit is highly appraised for meeting different demands.
