Product Description:
The compressor systems are categorized into three types depending on the evaporating temperature and nominal power. The three types of compressor systems are high-temperature type, intermediate-temperature type, and low-temperature type.
The high-temperature type compressor system is designed to operate at an evaporating temperature ranging from 12.5°C to -10°C. The compressor motor of the high-temperature type has a nominal power ranging from 60HP to 600HP.


The intermediate-temperature type compressor system is designed to operate at an evaporating temperature ranging from -15°C to -30°C. The compressor motor of the intermediate-temperature type has a nominal power ranging from 50HP to 540HP.
The low-temperature type compressor system is designed to operate at an evaporating temperature ranging from -35°C to -45°C. The compressor motor of the low-temperature type has a nominal power ranging from 50HP to 540HP.

Applications:
When it comes to refrigeration systems, there are high-temperature, intermediate-temperature, and low-temperature types. For the High-temperature Type, the evaporating temperature ranges from 12.5°C to -10°C, making it suitable for a wide range of applications. The compressor motor of the High-temperature Type typically has a nominal power of 60HP to 600HP, providing ample power for the system to operate efficiently.

The Intermediate-temperature Type, on the other hand, typically operates with an evaporating temperature between -15°C to -30°C. This type of system is commonly used in refrigeration applications such as cold storage rooms, walk-in freezers, and refrigerated trucks, among others. For the Intermediate-temperature Type, the compressor motor usually has a nominal power of 50HP to 540HP, providing enough power to maintain the set temperature effectively.
Finally, the Low-temperature Type is designed to operate with an evaporating temperature of -35°C to -45°C, making it suitable for ultra-low temperature applications such as scientific research labs and industrial processes. This type of system also typically has a compressor motor with a nominal power of 50HP to 540HP, ensuring that the system can maintain the desired temperature with ample power.
