Product Advantages

1. Compact Structure, Stable Operation:

The unit utilizes an imported high-efficiency fully hermetic scroll compressor paired with condensers and evaporators featuring high-efficiency heat transfer tubes. This results in a compact overall design, small footprint, light weight, low installation space requirements, and reliable, smooth operation.

2. Intelligent and Energy-Saving Control:

Equipped with a sophisticated energy control system that automatically adjusts unit operation (including start/stop cycles) based on real-time load changes, ensuring optimal energy efficiency.

3. User-Friendly Operation:

Features a microprocessor-based controller (with Chinese or digital display) that guides users via an intuitive on-screen/panel menu. Operation is as simple as touching the corresponding buttons.

4. Comprehensive Safety Protection:

The microprocessor controller integrates multiple protective functions, including compressor overcurrent, pump overcurrent, chilled water flow switch, low/high chilled water outlet temperature, compressor overload, frequent start/stop protection, abnormal voltage, and high/low pressure protection, ensuring safe and reliable operation.

5. Efficient and Eco-Friendly Configuration:

The air-cooled refrigeration design offers high energy efficiency and low operational noise. It requires no cooling tower or associated water pump, simplifying the system and meeting environmental requirements.

6. Quick and Easy Installation:

The unit is fully assembled and factory-tested prior to shipment. On-site installation only requires connection to the electrical power supply for immediate commissioning, making the process exceptionally straightforward.
