Core Advantages

1. Professional Anti-corrosion Design, Adapt to Harsh Chemical Working Conditions

   Both the evaporator and condenser adopt anti-corrosion shell-and-tube high-efficiency heat exchangers, with special anti-corrosion treatment for the corrosive water quality and process environment in the chemical industry, which greatly improves the service life of the equipment, and can stably adapt to strong corrosion scenarios such as electroplating, anodizing, and chemical synthesis.

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. Matched with thermostatic expansion valve for precise temperature control, the unit's COP value is leading in the industry. It can realize 0-25%-50%-75%-100% stepless capacity adjustment, accurately match the actual load demand, and greatly reduce operating energy consumption.

3. Fully Intelligent Control System, Easy to Operate and Maintain

   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.

4. Multiple Safety Protection Mechanisms, Ensure Long-Term Stable Operation

   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 7×24 hours continuous and stable operation of the equipment.

5. Support Non-standard Customization, Adapt to Diverse Process Needs

   We can provide customized solutions according to the customer's personalized requirements such as process temperature, water quality, installation space, and explosion-proof requirements, to meet the special refrigeration needs of different scenarios in the chemical industry.
