Designed, tested and manufactured in Daikin’s own laboratories.

Launch of STEPLESS capacity control(Sales launch: August 2005)

Saves the environments resources …and nevertheless your own resources

Better partial load control WHAT YOU WANT IS WHAT YOU GET

More precise control of the temperature OUTLET CONTROL (± 0.5oC)

Smaller minimum water volume required Upto 40% less than stepped chillers

Less need for buffer tanks

G-type stepless
