The stepless compressor is a DAIKIN development !
Designed, tested and manufactured in Daikin’s own laboratories.
Air conditioning – Refreshes your life
Stepless Single Screw Compressor
Launch of STEPLESS capacity control
(Sales launch: August 2005)
Better control of the chiller at partial load
 WHAT YOU WANT IS WHAT YOU GET
G-type stepless
More accurate control of the temperature
 OUTLET CONTROL (+/- 0,5°C)
If water quantity chiller + system ≥ minimum water quantity
 No buffertank required
Saves the environment’s resources …
and nevertheless your own resources
DAIKIN compressor = the compressor that you can count on
Designed, tested and manufactured in Daikin’s own laboratories.

How does it work ?
Pilot Valve
Loading and unloading via Pilot Valve:
-Pilot valve is driven by rod mechanism
-The rod mechanism is driven by

One control platform, pCO² digital controller
The pCO² gives you stronger control functions …
• Ensures efficient & harmonious operation of unit
• Efficient control of the chilled water temperature
• Control operating range of unit
• Manage safe operation of unit
• Provide useful information to the user
 Schedule time groups (4)
 Floating set point according to ambient temp.
 Comprehensive control logic for independent free cooling
 Load shedding through capacity setback (night setback)
 Customized control by programmable input/outputs
 D.I.C.N. = Daikin Integrated Chiller Network
Combine up to 4 Daikin chillers as if they were 1 unit
