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

The stepless compressor is a DAIKIN development !


Stepless Single Screw Compressor

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


Saves the environment’s resources …and nevertheless your own resources

DAIKIN compressor = the compressor that you can count on

Better control of the chiller at partial load WHAT YOU WANT IS WHAT YOU GET

More accurate control of the temperature OUTLET CONTROL (+/- 0,5°C)

If water quantity chiller + system ≥ minimum water quantity No buffertank required

G-type stepless



STEPLESS capacity regulation


The compressor has built-in capacity control by 15 – 100% by stepless slide valve mechanism, and adjustable volumetric ratio

STEPLESS capacity regulationHow does it work ?

Loading and unloading via Pilot Valve:

-Pilot valve is driven by rod mechanism

-The rod mechanism is driven by shaded-pole motor
