Multi V Plus III

MULTI V Inverter system offers one of the world's largest capacity units, essential for high-rise buildings. We are proud to say the system will ensure the highest level of customer satisfaction.
High cooling and heating COP

High efficiency BLDC V-scroll inverter compressor
High efficiency BLDC inverter fan motor
High air volume fan
Optimal heat exchanger distribution





Maximum single unit capacity of 20 HP

MULTI V lll offers bigger capacity of 20 HP for a single unit. Two basic modules, One Fan (up to 12 HP) and Two Fans (up to 20 HP), can be combined freely. Since one outdoor unit is enough to heat and cool a large area, the design of the MULTI V lll is simple and installation costs are kept to a minimum.





Technical innovation for high COP

As MULTI V lll has high efficiency parts, advanced interver control technology and optimal cycle control technology, the system's unified performance has been improved. Based on these advanced technologies, the product provides customers value through high efficiency and energy savings.





Continuous heating operation*

Continuous heating operation is possible with this product. Usually, when heating is being operated, freezing occurs in an outdoor unit heat exchanger. In such a situation, the usual way to solve this is to stop the indoor units and perform the defrost operation on the heat exchanger. However, since MULTI V III uses the split defrost technology it can operate heating continuously without stopping any indoor units, improving heating efficiency and always maintaining a warm indoor environment.

* Continuous heating operation can be switched to existing defrost mode depending on environmental conditions.





Night silent operation

By using, fan control technology and the real-time outdoor temperature detection technology, the product is equipped with the night low-noise operation function. 9 steps of low-noise operation are possible to provide more quiet operation during the night.

Real-time smart operation





Extended piping length and elevation

Because of the product's use of inverter control technology and sub-cooling control circuit technology, it is possible to design a system with longer piping length and world-class elevation difference. With this product, since a cooling and heating system can be designed more flexibly in a high-rise building or complex facilities building, the esigner's working time is reduced, thus allowing a more efficient design.





Space utilization by smaller size

The product size is reduced by up to 38% compared to the conventional products, reducing the required installation space greatly. This gives you more free space and thus allows for easier HVAC design.





Maximum combination capacity of 80HP with a single pipe

A combination of up to 80 HP can be made using 20 HP units. This makes it possible to design a HVAC system that fits into an extensive space. The usual major problems in design, such as installation space for outdoor units, pipe shaft space and piping line, are no longer an issue.





Eco-friendly design

We produce not only high efficiency products that have excellent energy-saving capability, but we also develop eco-friendly products with green technology that protect the earth and the environment. With these products, we are leading the world in low carbon and green development.





R410A Refrigerant

R410A is an eco-friendly refrigerant, with zero Ozone Depletion Potential (ODP). Since all the products use R410A refrigerant, they exhibit higher efficiency and energy-saving capability compared to products that use the conventional R22, thus contributing to global environmental protection.





No refrigerant leakage design and production





Auto leakage detection

The product monitors the operation status data in real time and decides the appropriate amount of refrigerant and displays it. It also automatically notifies the user of any small refrigerant leakage.





Refrigerant recovery and reuse

When performing maintenance on the product, the refrigerant is not discharged to the air but can be saved by collecting it in an outdoor unit, a refrigerant pipe or an indoor unit. This increases environmental protection and reduces costs.





New designs for low noise operation

To provide our customers with high cooling and heating performance at a minimum size, and as well as a pleasant environment ensured by quiet operation, MULTI V III uses various low noise technologies. It has minimized operation noise by using a compressor with BLDC motors, low noise fan motors, new soundproof technology, outdoor fans, and a newly developed shroud shape.
