Aqua Setter Aquozu: Ultra High Liquid Pressure Tube Expansion machine

EXP_AQUOZU

AQUOZU

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.

Principle of Liquid Pressure Tube Expansion

Ultra-high pressure water acts on the aqua tube to expand the tube.

Features

  1. Environment Friendly
    : Water-assisted, clean, environment-friendly tube expansion.
    Work environment improved with oil leak-free servomotor.
  2. 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.
  3. Easy Operation
    : Even thick tube can be expanded at your fingertips.
    Foolproof equipment with touch-screen system.
  4. Safety
    : As no resistance force is generating during expansion, it improves
    safety of operation.
  5. Improve Quality
    : No tube deformation and tube inner diameter hardening/flaking is generated.
