Customer Reviews

Jennifer Anderson

The chevron-type mist eliminators have been crucial in our distillation tower, preventing liquid carryover and improving product quality. Combined with their robust tower internals, we’ve seen a 30% reduction in equipment downtime. The team’s attention to detail in design—from material selection to flow optimization—makes them our go-to supplier for tower solutions.

Michael Brown

The tower internals from Changzhou Sanli Tech have transformed our packed bed operations. The liquid trough distributors efficiently handle high flow rates, and the gas spargers ensure uniform steam distribution. Made from durable stainless steel and special alloys, they resist scaling even in harsh conditions. The mesh mist eliminators have significantly improved product purity while reducing equipment damage. A reliable solution for our chemical processes!
