Key Features & Technology

It's the unique features of Daikin products that makes us the world leader.

... ...
...
Top Class Efficiency

Four efficiency tiers with 3 sound configurations providing full flexibility to meet customer needs.

...
Extended Operating Envelope

New TZ-D is the perfect solution for comfort applications as well as process and critical cooling thanks to the widest range of operating condition: Outdoor conditions: from -20°C up to +55°C. Supplied chilled fluid from -12°C up to +30°C.

...
Low Environmental Impact

The very low GWP of R1234ze (low direct emissions) combinedwith the reduced power consumption (low indirect emissions) result in the best Life Cycle ClimatePerformance (LCCP).

...
Outstanding Reliability

Each compressor is provided with a Variable Frequency Drive (VFD) installed on the compressor and cooled directly by the refrigerant. Daikin technology offer real independency from outdoor conditions (temperature, humidity, altitude, pollutions) and continuously operate in the most extreme conditions.

...
Fan Silent Mode

Units with EC motor fans offer a fan silent mode. This feature lets users set specific time bands to reduce fan rotation speed and minimize sound emission during nighttime hours. This results in quieter operation, with a reduction of approximately -4dB(A) depending on the unit model and operating conditions.

Range Overview

The IV generation of TZ chiller is available with 3 refrigerants

3 refrigerants:

  • R1234ze (EWAH)
  • R513A (EWAS)
  • R134a (EWAD)

All available in four efficiency tiers:

  • Blue (B-) (avg. EER = 2,9 ; avg. SEER = 4,7)
  • Silver (S-) (avg. EER = 3,1 ; avg. SEER = 5,5)
  • Gold (X-) (avg. EER = 3,4 ; avg. SEER = 6,0)
  • Platinum (P-) (avg. EER = 3,7 ; avg. SEER = 6,6)

Three sound configurations

  • Standard Noise
  • Standard Sound + option 76-b (compressor enclosure)
  • Reduced Sound
