Ultra Low Ambient Air Cooled Chiller (Heat Pump) Unit | Screw Compressor Chiller for -20℃ Heating

The Ultra Low Ambient Air Cooled Chiller (Heat Pump) Unit is a heavy-duty HVAC solution engineered for reliable cooling and heating in extreme cold climates. Powered by a high-efficiency screw compressor, this unit delivers stable operation even at -20℃ ambient temperature, making it ideal for regions with harsh winters.

🔧 Key Features & Advantages

1. High-Efficiency Screw Compressor
At the core of the unit is a high-efficiency screw compressor, designed for continuous operation under heavy loads. The Screw Compressor Chiller offers low vibration, quiet operation, and exceptional durability, ensuring years of trouble-free service.

2. Ultra-Low Ambient Heating Capability
This Ultra Low Ambient Chiller is specifically engineered for cold climates. Both low-temperature and ultra-low-temperature versions are available, with the ultra-low model providing stable heating performance down to -20℃. This makes it a true Low Temperature Heat Pump, capable of maintaining indoor comfort without auxiliary electric heaters.

3. Air Cooled Design for Easy Installation
As an Air Cooled Chiller Heat Pump, the unit rejects heat to the outdoor air, eliminating the need for cooling towers or condenser water loops. This simplifies installation, reduces maintenance, and saves valuable mechanical room space. The unit is ready for outdoor placement with weather-resistant casing.

4. High Efficiency & Energy Savings
The screw compressor, combined with optimized fin-tube heat exchangers and electronic expansion valves, delivers high COP and EER values. The unit also features part-load efficiency improvements, reducing energy consumption during off-peak conditions.

5. Reliable Operation in Harsh Conditions
The unit is equipped with crankcase heaters, anti-freeze protection, and defrost controls to ensure reliable operation during freezing weather. The robust steel frame and corrosion-resistant coating extend service life in outdoor environments.

6. Modular Capacity Options
Multiple units can be combined in parallel to match the heating/cooling demand of large buildings – from hospitals and cleanrooms to hotels, office buildings, and industrial plants.
