Feature

1. Advanced Screw Compressor Technology

Superior Efficiency: Utilizes semi-hermetic screw compressors from world-leading brands, optimized for eco-friendly R134a refrigerant.
Flexible Control: Infinite Capacity Control or 4-step loading allows the unit to match the building's actual load precisely, maximizing energy savings even at 25% part-load operation.

2. Optimized Heat Exchange System

Flooded Evaporator Technology: The flooded-type evaporator design significantly enhances heat transfer efficiency compared to conventional types, while ensuring easy maintenance and copper tube cleaning.
V-shaped Condenser: The V-shaped structure optimizes airflow, increases the cooling surface area, and reduces the overall unit footprint, saving valuable installation space.

3. Intelligent Control & Comprehensive Connectivity

Electronic Expansion Valve (EXV): Provides fast and precise response to cooling load variations, ensuring the system consistently operates at its most stable state.
Economizer Feature: An integrated economizer enhances cooling capacity and operational efficiency without increasing the compressor size.
Remote Monitoring: Supports RS485 communication interface, allowing seamless integration into Building Management Systems (BMS) for centralized monitoring and control.

4. Extreme Environment Adaptability

Wide Operating Range: The unit operates stably in extreme ambient temperatures ranging from -32°C to 55°C, making it suitable for all climates, from scorching tropical heat to freezing temperate zones.
Diverse Options: Available in Fixed Speed or Inverter (Variable Speed) models, meeting international T1/T3 standards.

5. International Quality Certifications

Products are tested at national-standard testing stations (with capacities up to 1,650kW).
Complies with rigorous quality standards, ensuring that real-world technical specifications are 100% accurate compared to the data provided by the Selection Software.
