Definitely excellent supplier and sales team. They helped me purchase a 12000BPH water production line this April. I'm a mineral water producer from SA and as new to the industry, so I was looking for a supplier who could provide me with comprehensive support and guidance throughout the process. From factory configuration to after-sales service, Hengyu sales team was with us every step of the way. They helped us choose the right equipment as well gave us a very competitive price. Working with them was a real pleasure. Our water plant just opened a few days ago, and when we need to purchase more in future, I would turn to you again. Good job guys!
