Core features and technical advantages

• Powerful and reliable "heart": using German Bitzer semi-hermetic piston compressor. Bitzer compressor is well-known in the refrigeration industry for its high performance, high reliability and stable operation, especially suitable for medium and low temperature applications. Its good quality and reliable operation
• Efficient heat exchange system: The unit is usually equipped with a high-efficiency finned air-cooled condenser, which has high heat exchange efficiency and long service life. The evaporator can be designed for corrosion resistance according to the properties of the refrigerant (such as corrosiveness).
• Intelligent control and comprehensive protection: Modern industrial chillers often feature a liquid crystal display (LCD) human-machine interface (HMI) for easy operation and a clear overview of operating status. Multiple safety protection devices are integrated into the units, typically including high and low voltage protection, motor overload protection, phase loss/reverse phase protection, antifreeze protection, and water flow protection, ensuring safe operation under various operating conditions.
• Adaptable and convenient design: The air-cooled design eliminates the need for additional cooling towers and cooling water pumps, reducing installation complexity and supporting infrastructure costs. The unit can be equipped with its own water tank and circulating water pump, depending on cooling capacity. The unit is typically designed for 24-hour operation, meeting the cooling needs of continuous production processes.

Application Scenario

This type of chiller, which can provide a low temperature of -30°C, is commonly used in the following areas:

• Chemical industry: low-temperature cooling of reactors and material crystallization processes.
• Medicine and bioengineering: low-temperature extraction, freeze-drying, and low-temperature storage of drugs.
• Food processing: quick freezing (IQF), low temperature refrigeration.
• Low-temperature freezing and cold storage: Provide the cooling capacity required for low-temperature warehouses.
• Others: Environmental test chambers, laser technology, vacuum coating and other processes that require low-temperature cooling.

Selection and usage precautions

1. Verify key parameters: Be sure to confirm with the supplier the actual cooling capacity at a -30°C outlet water temperature. The cooling capacity of the unit will vary significantly under different operating conditions.
2. Indicate the type of refrigerant: inform the supplier of the type of refrigerant you plan to use (such as the concentration of ethylene glycol water solution) so that they can make corresponding anti-corrosion designs for components such as the evaporator.
3. Confirm environmental adaptability: Understand the unit's requirements for ambient temperature and ensure that it can operate normally at the highest ambient temperature at your installation location.
4. Focus on energy efficiency and operating costs: Choosing a compressor with a high energy efficiency ratio and an optimized design of the whole machine will help reduce long-term electricity costs.
5. Consider installation and maintenance: While air-cooled units simplify installation, the installation site still needs to be well-ventilated to facilitate heat dissipation and maintenance. It's also crucial to choose a supplier with excellent after-sales service and timely technical support.
