Well-shaped externals（Small, Light, and Compact）
 Small, Light, and Compact design.
（50% lighter than previous type.）
The installation space has been minimized without spoiling an environmental fine sight.
All wires are built into the machine.
（There is no exposing wire.）

Quick opening and closing
The opening and closing speed can be three times and programmable.
In emergency , high-speed closing is possible.
At first it opens slowly, and later becomes high-speed (1.0m/min).
When it is closing, high-speed re-try mode (to remove the obstacle by the repetition of opening and closing at the position) and flushing mode (to clean the bottom of the penstock by high-velocity water flow of narrow bottom space) are available as standard function. |
|
Easy maintenance（Reduction in life cycle cost）
 The oil exchange is concentrated in one place, and the amount of wasted oil become 1/10.
Reliability improved greatly according to the parts become 1/5 by simple design. |
|
Simple＆Ubiquitous（Corresponds with communication facilities）
Immediate operation just by plugging in. (Built-in control panel is standard）
Superb reliability through all-in-one design.
Capable of easy connection to various telecommunication systems.（option） |
