New Casing

New reinforced design

The frame structure has been strengthened to improve resistance to earthquakes and wind while protecting against falling damage.

Strongly resists earthquakes and high winds

Withstands 7 seismic
intensity earthquakes※1

Evaluation:
National Institute of Technology and Evaluation (NITE), an independent Japanese administrative institution

A vibration test conducted on a Japanese model*1 used vibration equivalent to a 7 seismic intensity earthquake to confirm no damage or effect to the refrigerant or electrical systems while showing the unit remained in good operating condition.

Withstands 60 m/s winds※2

An experiment conducted on a Japanese model used a force equivalent to a wind speed of 60 m/s to confirm that there was no risk of the unit falling over or suffering damage to any of its parts.

Cross-sectional images of the outdoor unit from above

Wind blowing from the front

The unit remains upright even when hit with a force equivalent to a wind speed of 60 m/s from the front.

Wind blowing from the rear

The front panel remains attached even when hit with a force equivalent to a wind speed of 60 m/s from the rear.

Vibration tests were conducted on the Japanese model, recreating the seismic waveforms of the area (Kurihara City, Miyagi Prefecture) where the maximum seismic intensity of the Great East Japan Earthquake was recorded.
• The magnitude of an earthquake depends not only on its intensity but also on its gal (acceleration) and natural period. Please inspect the outdoor unit after an earthquake occurs.

The outdoor unit should be installed on a concrete surface on the ground or on a mounting surface with equal or greater strength.

Energy Savings

Further energy savings have been achieved through the evolution of software and hardware technologies.

Improves Energy Efficiency Ratio (EER)

New VRV 6 X series improves energy efficiency during actual operation (low load), equipped with a new compressor, new heat exchanger and VRT Smart II control.

Hardware technology

A Parallel Flow Condenser (PFC) heat exchanger designed for the new VRV 6 X series.

High Efficiency – Higher Heat Exchanging performance

Superior corrosion resistance for long-term reliability

By reducing the risk of rust and surface damage over time, Silver HeatX helps extend the life of your equipment, lowers maintenance costs, and ensures stable performance in any climate.

Helps the environment – Equivalent to planting 388 cedar trees

*CO₂ reduction is calculated based on the GWP of R-410A (2,090) and an estimated annual CO₂ absorption of 14 kg per cedar tree. Actual values may vary depending on tree species, age, environmental conditions, and refrigerant type.

Hardware technology
High Efficiency Compressor

New technologies increase seasonal efficiency and enable a compact design

Software technology
VRT Smart II Control

Optimal supply exactly meets the required capacity of indoor units

Further improvement of energy savings is achieved due to optimal control of the outdoor airflow rate.

Reliability

Designed to withstand hard environments.

IP55 sealed electrical component box

IP55 sealed component box protects electrical component from a cause of failure, that is the ingress of debris (lizards, bugs, sand, water).

The internal mounting plate is hinged, enabling easy maintenance of the PCB on the back.

Gecko Experiment on the Electrical Component Box

Individual electrical component boxes were used to conduct accelerated testing of gecko ingress, considered a frequent cause of failures in the market. An electrical component box was placed in an acrylic box along with 20 geckos, for 24-hour tests conducted over four days.

Enables operation in high outdoor temperature

Three refrigerant cooling circuits enable stable operation even in high outdoor temperatures by suppressing a temperature rise for the PCB mounted in the sealed electrical component box.

Expanded operation temperature range

The outdoor operation temperature range is now extended from 49 to 52°C. This enables reliable operation even under high temperature conditions and a wider choice of installation locations.

Keep rated cooling capacity in high outdoor
temperature up to 43°C*

Rated cooling capacity can be maintained even when outdoor temperature is up to 43°C*.
*Rated cooling capacity for 16-20 HP is up to 42°C.

IP55

IP55 is the degrees of dust and water protection for the electrical component box equipped on the product.

IP55

*IP55 is the protection degree of the wiring box as a single unit. The protection grade of outdoor unit is IP14 as well as conventional model.

Design Flexibility

Long piping length enhances design flexibility, enabling support for large buildings.

Long refrigerant piping

Simultaneous extension of height difference and equivalent length

Design flexibility is further improved by simultaneous extension of height difference, improved from 90 m to 110 m, and equivalent length (up to 190 m).

Height difference extension
Max. 110 m

For height differences exceeding 50 m with the outdoor unit above the indoor unit and 40 m with the outdoor unit below, the main piping liquid piping size must be increased.

The operating temperature range is up to 49˚C (Outdoor units above indoor units only).
The minimum connection capacity index of the indoor unit shall be 62.5 (7.1 kW) or more (Outdoor units above indoor units only).
Equivalent length extension
Max. 190 m

When the equivalent piping length from outdoor unit to indoor unit is 90 m or more, be sure to increase the size of the liquid and gas pipes of the main piping.

* In addition to increasing the size of the main pipe, there are other piping restrictions regarding height difference extension and equivalent length. Check the Installation Manual for details.

REFNET header downstream branching supported

Piping branch by REFNET joint is possible downstream of REFNET header.
The indoor unit arrangement can be more flexible.

Easy Installation

New structure improves installability.

Automatic refrigerant charge function

Simultaneous extension of height difference and equivalent length

Contribute to optimised operation efficiency, higher quality and easier installation.

Electrical component service window

Main PCB 7-segment LED and setting buttons can be accessed without removing the front panel. Workability has been highly improved for servicing and field settings.

Process visualization
(Test run only^*)

In the new models, in addition to the actual step (t01 to t10), a progress rate (0% to 99%) is available as a guideline when making arrangements for on-site work.
* Effective when test run is carried out independently after manual refrigerant charging.

Improved refrigerant piping workability

By dividing piping and wiring holes to the left and right, piping and wiring work can be easily performed on site.

Comfort

Suppresses the nighttime operating sound to maintain the quiet environment.

Nighttime quiet operation function

The nighttime quiet operation function automatically suppresses the nighttime operating sound by reducing operation capacity to maintain the quiet environment of the neighborhood.
Three selectable modes are available depending on the required level.

*1. Initial setting is 8 hours. Can be selected from 6, 8 and 10 hours.
*2. Initial setting is 9 hours. Can be selected from 8, 9 and 10 hours.
*3. In case of 6-12 HP outdoor unit.

Notes: This function is available in setting at site.
The operating sound in quiet operation mode is the actual value measured by our company.
The relationship of outdoor temperature (load) and time shown above is just an example.
