About Mazelu

A heat exchanger manufacturer in Wuxi, China, working mainly on custom and equipment-integrated projects.

What we manufacture

Three product lines: finned tube heat exchangers, shell and tube heat exchangers, and spiral plate heat exchangers. Finned tube units are the main line, covering air heating, air cooling, flue gas heat recovery and special duties such as process gas cooling and thermal storage bundles.

The company builds pressure-bearing equipment, so shell and tube and spiral plate units can be manufactured and inspected for pressurized duty.

Team

Our team handles thermal design, mechanical design and process engineering. Finned tube forming, tube bundle assembly, casing fabrication, pressure testing and final inspection are all carried out at our works in Wuxi.

How we work

Most of our projects are not catalogue sales. We are brought in while the customer's equipment is still being developed, and we take the heat exchanger from requirements and thermal calculation through prototype build and test validation, then into series production. That is the pattern behind our photovoltaic, hydrogen and drying equipment work.

  • Heat exchanger geometry built to the host equipment envelope, not the other way round
  • Prototype validation before any series commitment
  • Process and inspection consistency maintained across production batches

Export track record

We have supplied high-pressure copper tube, copper fin steam heaters to the Russian market in series for a number of years, and delivered a copper tube with carbon steel shell heat exchanger to Italy. Both are in operation.
