Key Features
-
Lower Environmental Impact
Three refrigerant models are offered, including R1234ze, R513A or R134A to choose from for the best fit. R1234ze refrigerant has a GWP value of 1* and will reduce potential direct emissions. -
TOP CLASS EFFICIENCY
Compact footprint with EER up to 3.7 and IPLV up to 7.4 available on the Platinum version delivering high efficiencies at both full load and part load. -
ADVANCED COMPRESSOR TECHNOLOGY
Single screw compressor designed and manufactured by Daikin has a new 3:10 geometry optimised for high rotational speed. Each compressor is equipped with a Variable Frequency Drive (VFD) and cooled directly by refrigerant. -
EXTENDED OPERATING ENVELOPE
Operational envelope can be extended through a selection of specific options to operate -20°C up to +55°C and supply chilled fluid from -12°C up to +30°C. -
NOISE REDUCTION
The optimised “V” angle on the condenser combined with in-house developed innovative fan design increases airflow while delivering lower noise levels in conjunction with optional full metallic insulated soundproof compressor enclosure. -
INTEGRATED ACTIVE HARMONIC FILTER
Optional Daikin Design Integrated Active Harmonic Filter shares the same technology as refrigerant-cooled VFD, designed to reduce the Total Harmonic Distortion (THDi) to less than 5%.
