Product Details
Product introduction
Product Overview
Air-cooled scroll chillers are high-efficiency refrigeration units that utilize scroll compressors and air-cooled condensing technology. They provide chilled water (typically 7–12°C) for buildings or industrial processes via refrigerant circulation. These integrated systems eliminate the need for cooling towers and are ideal for small to medium cooling demands.

Core Components
* Scroll Compressor: Compresses refrigerant via meshing scrolls, ensuring quiet and stable operation.
* Air-Cooled Condenser: Uses fans to dissipate heat, condensing high-pressure refrigerant gas into liquid.
* Evaporator: Absorbs heat from the water system, generating chilled water.
* Electronic Expansion Valve: Precisely regulates refrigerant flow to optimize efficiency.

Working principle of the unit
Workflow
Refrigerant is compressed → High-temperature gas enters the condenser → Liquid refrigerant expands via the valve → Evaporates in the evaporator → Returns to the compressor.

Products Description
Compressor
The unit adopts the world famous brand compressor, which can realize the efficient operation of the full pressure ratio and obtain better comprehensive operation efficiency.
Title goes here.
Semi-Automatic PET Bottle Blowing Machine Bottle Making Machine Bottle Moulding Machine PET Bottle Making Machine is suitable for producing PET plastic containers and bottles in all shapes.
Electronic EEV
Precise adjustment of cooling capacity, more energy-saving operation. Adopt high-precision electronic expansion valve to ensure stable and efficient operation under all working conditions.
Water-side heat exchanger
The water-side heat exchanger adopts a new shell-and-tube heat exchanger with high efficiency, and the heat exchange tube is a high-efficiency copper tube with internal thread, which enhances the heat exchange efficiency between the water side and the refrigerant side, optimizes the pipeline layout and baffle design, ensures low water resistance and high efficiency, and has a large internal waterway flow area, which is not easy to block and scale, prolongs the cleaning cycle and ensures the long-term operation stability of the unit.
Condensing fan
Adopt high efficiency and low speed fan, low noise, and adopt fully sealed scroll compressor, with rubber shock absorber at the bottom as standard, which runs smoothly.

Installation Instructions
Unit hoisting
When lifting with a crane, handle it carefully. Use a flat belt or steel cable to bind the lifting steel pipe for lifting. There should be a pad at the contact between the steel cable and the machine to avoid injury to the equipment. The steel cable at the hook should be wound around the hook to avoid danger due to unbalanced weight.
Unit installation specification
The installation of the unit shall meet the following requirements: 1)Ensure that air inlet and exhaust are smooth; 2)Avoid being affected by dirty and corrosive airflow; 3)There should be room for outdoor unit maintenance; 4)The impact on the surrounding environment should be minimized; 5)Condensate and defrosting water should have drainage channels. 6)Unit installation refer to the recommended spacing to ensure smooth airflow. There should be no obstacles up there. If the top space is insufficient, install a curved air duct to direct the air far away to avoid short circuit and affect the unit performance.
