Aqua Setter Aquozu: Ultra High Liquid Pressure Tube Expansion machine
Lightweight, compact, energy-saving and space-saving tube expansion equipment!
Aquozu is a tube expansion machine which expands tubes by ultra-high pressured water and servomotor is
installed as a driving source. Ultra-high pressured water works inside a tube and this makes the tube fixing to
the tube sheet by a plastic deformation. This machine is suitable for thick and/or long tube expansion.

Features
- Environment Friendly
: Water-assisted, clean, environment-friendly tube expansion.
Work environment improved with oil leak-free servomotor. - Economical : With its ability to expand 800mm in a single expansion, Aqua Setter Eco greatly reduce the expansion time and total cost.
generated.in thickness. - Easy Operation
: Even thick tube can be expanded at your fingertips.
Foolproof equipment with touch-screen system. - Safety
: As no resistance force is generating during expansion, it improves
safety of operation. - Improve Quality : No tube deformation and tube inner diameter hardening/flaking is generated.
Application Examples
- Feed water heaters for power generation plants
- Tube reactors for natural gas plants
- Heat exchangers for petrochemical plants, etc.
