This vertical tube expander is specially designed for heat exchanger coil production. It can expand copper tubes, enlarge tube ends and flare tube ends in one cycle, to make copper tubes and aluminum fins join tightly for higher heating exchange efficiency.
The machine adopts centralized compulsive lubricating system for whole equipment lubrication.
For large-size heat exchanger coil production, horizontal tube expanders will be used
For small-capacity workshops, portable tube expanders will be a good option
