Product Features
Wide Capacity Range

The Ultima VRF system offers a robust capacity, ranging from 28,000 to 60,000 British Thermal Units per hour (BTU/h). This wide range allows it to adapt to various environmental conditions and requirements, thereby demonstrating its versatility.

One primary benefit of the Ultima VRF system’s extensive capacity range lies in the reduced necessity for numerous outdoor units. Its efficient performance means that fewer units are required to meet the same cooling or heating demands. Consequently, a significant amount of outdoor space can be conserved, leading to a more streamlined and aesthetically appealing setting.

1 to 9 Indoor Units Connection

The Ultima VRF system is designed with space efficiency in mind, with each outdoor unit capable of supporting between 1 to 9 indoor units. This design means that fewer outdoor units are needed, freeing up substantial outdoor space and reducing clutter.

Imagine the possibilities for your backyard or outdoor area when it isn’t filled with multiple HVAC units. The reduced number of outdoor units that the Ultima VRF system requires, creates more available space, allowing you to utilize your backyard more effectively and wisely. Whether it’s for landscaping, a play area, an outdoor dining space, or a garden, the Ultima VRF system can help you reclaim your outdoor space.

Wide Range of Indoor Units

The Ultima VRF indoor unit series presents a comprehensive selection of models to cater to diverse indoor needs, with capacities spanning from 5,000 to 56,000 British Thermal Units per hour (BTU/h). This broad array of options allows users to pick the most appropriate model for their particular requirements.

The Ultima VRF series encompasses models such as the One-way Cassette, Four-way Cassette, and the more space-efficient Compact Four-way Cassette. For those who prefer wall-mounted options, the Ultima VRF series offers Wall-mounted units, in addition to the versatile Ceiling & Floor units. For more unique cooling and heating requirements, especially in larger or more complicated spaces, the Medium Static Pressure Duct, Arc Series Duct, and High Static Pressure Duct models are available.

With such a diverse range of indoor units, the Ultima VRF series can meet a wide variety of indoor needs, enhancing comfort, convenience, and efficiency across different environments and settings.

DC Inverter Compressor

The use of DC inverter compressors in the Ultima VRF system allows for the output of the outdoor unit to be directly modulated according to the specific cooling or heating demands of the zone it is controlling. This sophisticated approach ensures a high degree of precision in temperature regulation, minimizing fluctuations and maintaining optimal comfort levels.

Moreover, this advanced system optimizes energy usage, contributing to its high efficiency. By only using the energy necessary to match the specific demands of each zone, the Ultima VRF system avoids energy wastage commonly associated with more traditional HVAC systems. This energy-efficient operation not only leads to lower energy costs but also makes a significant contribution to environmental conservation. By reducing the overall energy consumption and consequently reducing greenhouse gas emissions, the Ultima VRF system helps users contribute to a more sustainable future.

DC Fan Motor

The Ultima VRF system includes a DC fan motor, notable for its ability to provide stepless adjustment. This feature allows the fan motor’s speed to be precisely controlled in response to the varying cooling or heating demands, thus ensuring optimal performance at all times.

The stepless adjustment of the DC fan motor helps maintain the system at the lowest possible power consumption. By precisely matching the fan speed to the needs of the system, it minimizes energy waste, which not only results in lower operating costs but also contributes to more sustainable energy use.

By balancing optimal comfort with minimal energy consumption, the DC fan motor in the Ultima VRF system delivers both a highly comfortable environment and cost-effective operation. This advanced design results in a significant reduction in operational costs, making it a preferred choice for energy-conscious users.

Refrigerant Cooling PCB

The Ultima VRF unit employs refrigerant cooling technology to manage the temperature of the electric control box. This technology effectively reduces the average temperature of the electrical control components by approximately 8 degrees. This drop in temperature significantly enhances the stability and safety of the control system.

By maintaining a lower temperature, the refrigerant cooling technology helps to prevent overheating, which can cause system damage or inefficiencies over time. The cooler operating temperature ensures the long-term reliability and safety of the control system, reducing the risk of system failures or disruptions.

This cooling approach guarantees the consistent, safe, and efficient operation of the Ultima VRF unit, reinforcing the overall durability and longevity of the system. This ultimately leads to smoother operation, reduced maintenance needs, and longer service life, providing greater peace of mind for users.

Auto Addressing

The Ultima VRF system’s outdoor units automatically assign addresses to each indoor unit, simplifying setup and management. Furthermore, using remote or wired controllers, users can easily check or alter the address of any indoor unit, enhancing system control and efficiency.

Long Piping Length

The Ultima VRF Mini series offers considerable flexibility in system design due to its substantial piping length and height difference allowances. It supports a total piping length of up to 100 meters, facilitating a wide range of system configurations.

In addition, the system can manage a maximum height difference of 30 meters between outdoor and indoor units. This allows for installations across multiple floors or levels. Moreover, the permissible height difference between indoor units can be as great as 10 meters.

These generous allowances ensure that the Ultima VRF Mini series can accommodate a wide variety of system designs. This provides a greater degree of flexibility in meeting unique building layouts and individual user requirements.

Intelligent Defrosting Technology

The Ultima VRF system features an intelligent defrosting program that optimizes the defrosting process based on the system’s actual status. By calculating the necessary defrosting time, the program eliminates heat losses that may result from unnecessary or excessive defrosting.

Additionally, a specialized defrosting valve is incorporated into the system. This valve is designed to reduce the time required for defrosting significantly, bringing it down to as little as four minutes.

These advanced features ensure efficient defrosting processes that minimize energy consumption and maximize system performance. By optimizing defrosting based on actual needs, the Ultima VRF system enhances energy efficiency, operation reliability, and overall system longevity.

Multiple Priority Modes

The Ultima VRF system offers multiple priority mode settings, providing enhanced customization and flexibility to suit customer needs. These diverse settings ensure that users have the freedom to optimize their HVAC system according to their specific preferences and requirements.

Whether it’s prioritizing energy efficiency, rapid temperature changes, or maintaining a steady temperature, these customizable modes give users greater control over their heating and cooling systems. This increased freedom and convenience ensure a more personalized, efficient, and comfortable experience, making the Ultima VRF system a highly adaptable choice for a variety of settings and needs.
