Ambient & Outlet Water Temperature

Stable operation even under extreme conditions: -14°C to 43°C.

Note: For cooling mode, if outlet water temperature is less than 5°C, anti-freeze liquid is needed. 0°C water temperature can be reached by changing DIP switch setting.

High Quality Components

DC Inverter compressor

At the heart of the chiller lies a world-leading DC inverter compressor. The compressor’s innovative design and numerous high performance features reduce power consumption by 25%.

  1. Twin rotary structure
  2. High efficiency DC motor
  3. Highly stable moving parts
  4. Better balance and extremely low vibration

High Efficiency Plate Heat Exchanger

Plate heat exchanger uses metal plates to transfer heat between refrigerant and water. The fluids are exposed to a much larger surface area because the fluids spread out over the plates, so both heat transfer efficiency and heat exchanger speed are greatly improved. Multi protections including voltage protection, current protection, anti-freezing protection and water flow protection ensure system safety running.

DC Fan Motors

Fan speed is controlled according to the system pressure and system load, reducing power consumption by 30%. There are 32-step vector control.

Spray Liquid Cooling Control

Spray liquid cooling control, which is used for enhancing heating capacity in low temperature condition.

Precise Oil Control Technology

Four stages of oil control technology ensure all outdoor compressor oil is always kept at a safe level, eliminating any compressor oil shortage problems.

  • Compressor internal oil separation.
  • High-efficiency centrifugal oil separator (with separation efficiency of up to 99%) ensures that oil is separated from the discharge gas and returned to the compressors in a timely fashion.
  • Oil balance pipe ensures oil distribution to keep compressor running normally.
  • Auto oil return program monitors the running time and system status to ensure reliable oil return.

Intelligent Defrosting Technology

The intelligent defrosting program calculates the time required for defrosting according to the actual system status, eliminating heat losses from unnecessary defrosting. A specialized defrosting valve reduces time required for defrosting to as little as four minutes.

Rapid Cooling or Heating

The DC inverter compressor reaches full capacity rapidly, providing quicker cooling or heating with lower levels of temperature fluctuation during the cooling/heating operation.

Modular Design

Modularity is perfect when an extension of capacity becomes required as the building load range from 30kW to 960kW.

High Reliability

Alternate Defrost Operation

By detecting the water temperature, the proportion of defrosting unit can be determined intelligently so as to realize small water temperature fluctuation during the alternate defrosting period.

Alternative Cycle Duty Operation

In one combination system, all units operate as alternative in cycle duty to keep equal running time, realize higher stability, better reliability and longer lifespan.

Backup Function

In a combination system, if one unit failed, other units can be back-up instead of the failed one for continuing operation.

Multiple Slient Modes

Different silent modes enable noise reduction to suit time of day and ambient noise levels.

  • Standard mode
  • Silent mode
  • Super silent mode
  • Night silent mode

Weather temperature curve

With the help of weather temperature curve function, water temperature will automatically change as outside air temperature changes. When outdoor air temperature increases/decreases, the heating load will decrease/increase and water temperature will decrease/increase automatically. When outdoor air temperature decreases/increases, the cooling load will decrease/increase and water temperature will increase/decrease automatically.

Anti-Corrosion Protection

Outdoor units are given anti-corrosion treatment for non-extreme conditions as standard and can also be customized with heavy anti-corrosion treatment on main components for surface protection against corrosive air, acid rain and saline air (for installations in coastal regions) to extend machine life span. The integrity of the anti-corrosion treatment is ensured by subjecting major components and parts to salt mist testing, moisture and heating testing and light aging testing.
