Air-Cooled Screw Chiller Unit Product Introduction

Core Advantages

1. Air-Cooled Integrated Design, Convenient Installation and Simple Maintenance

   The unit adopts air-cooled heat dissipation design, no need for supporting auxiliary equipment such as cooling water towers and cooling water pumps, which greatly simplifies the installation process, reduces installation and maintenance costs, is perfectly suitable for water-scarce areas, scenarios with limited installation space such as rooftops/workshops, and can be put into use quickly.

2. International Brand Core Components, High-Efficiency and Stable Refrigeration

   It adopts internationally renowned brand semi-hermetic screw compressors with excellent energy efficiency ratio, low operating noise and long service life. It supports 33%-66%-100% stepless capacity adjustment, which can accurately match the actual load demand and greatly reduce operating energy consumption. Matched with Y-△/△-△ split winding starting method, the starting is stable and the impact on the power grid is small.

3. High-Efficiency Heat Exchange System, Adapt to Harsh Industrial Working Conditions

   The evaporator adopts a shell-and-tube high-efficiency heat exchanger, which has high heat exchange efficiency and strong anti-scaling ability, and can adapt to the complex water quality environment of industrial circulating water. The condenser adopts a high-efficiency copper tube with aluminum fin structure, which has excellent heat dissipation performance, high temperature resistance and corrosion resistance, and can operate stably in high temperature environments, ensuring the refrigeration demand of the equipment for 7×24 hours continuous production.

4. Fully Intelligent Control System, Multiple Safety Protection

   It is equipped with a fully automatic PLC control system, supports touch screen human-machine interaction, can real-time monitor the unit's operating status, adjust operating parameters, realize fault self-diagnosis and alarm, and support remote operation and maintenance, which greatly reduces the difficulty of on-site operation and maintenance. Built-in full-dimensional safety protection mechanisms such as high/low pressure protection, overload protection, current protection, phase reversal protection, oil pressure protection, discharge overheat protection, and compressor high temperature protection, which can effectively avoid various abnormal working condition risks and ensure the long-term stable operation of the equipment.

5. Full Coverage of Multiple Models, Support Non-standard Customization

   The full series covers the cooling capacity range from 100kW to 620kW. We can provide customized solutions according to the customer's personalized requirements such as process temperature, installation space, explosion-proof requirements, and power supply specifications, to meet the special refrigeration needs of different industrial scenarios.
