2. Advanced Compressor Control
- Step less compressor control
- Precise control technology of 0.1 Hz ensures your units operate as efficiently as possible.
- Outdoor units perform faster with improved scroll compressor’s dramatically extended range of rotation speed.
- Increases efficiency
3. Σ Shaped Heat Exchanger
- The heat exchange area has been increased by more than 10% (single module)
- Greater heat exchange efficiency
- The heat exchanger’s split structure creates a unique sigma shape to facilitate efficient cooling and heating.
- Increased heat exchange surface while preserving a small footprint
4. Air Outlet Design
- Improvement of air flow volume by 23% (single module)
- Energy consumption in the driving shaft has decreased by 20% on average
5. Smooth Drive Function
- Smooth Drive keeps the scroll compressor running at the optimal level by measuring the load level and calibrating the required amount of refrigerant.
- As a result, power consumption is reduced by almost 40%.
6. Improved External Static Pressure
- Less piping length
- Lower installation cost
- Visual aesthetics
7. Ambient Temperature Range
8. Piping Connection Workability
- Suitable for a high-rise building or complex facilities
- Leads to cost/time saving for designers, with more efficient design
9. Improved Strength
10. Maintenance Ease
- Easy maintenance via redesigned service access points
- Upper panel section provides high visibility and easy replacement of PCBs
- Lower panel is independently removable, allowing access to compressors and expansion valves for easy refrigerant recovery
