Stepless Single Screw Compressor
Launch of STEPLESS capacity control(Sales launch: August 2005)
Designed, tested and manufactured in Daikin’s own laboratories.
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 Single Screw Compressor
STEPLESS capacity regulation
Designed, tested and manufactured in Daikin’s own laboratories.
The compressor has built-in capacity control by 15 – 100% by stepless slide valve mechanism, and adjustable volumetric ratio
