Bitzer two stage compressor

Types of Bitzer two-stage compressors

A Bitzer two-stage compressor is a refrigeration compressor created to compress refrigerant in two stages. The first stage compresses the refrigerant partially, and the second stage completes the process. Two-stage compressors are more efficient than one-stage compressors because the refrigerant is more completely compressed. Additionally, two-stage compressors offer better control of the temperature in a building because the compressor can run at two different levels.

Generally, Bitzer compressors can be categorized based on the way they compress gas.

• Two-stage semi-hermetic compressors: These compressors are mostly used in industrial refrigeration applications. They function well with Bitzer refrigerants.
• Two-stage open compressors: Bitzer two-stage open compressors are mainly used in water chillers and industrial refrigeration systems.
• Two-stage helical-rotary compressors: These compressors are mostly applied in commercial refrigeration and air conditioning systems.

More specifically, the Bitzer two-stage piston compressor can be further divided into single and double pieces.

• Single-pistoned compressors: They perform partial compression of the refrigerant in the first stage and complete compression in the second stage.
• Double-pistoned compressors: They are more efficient than single-pistoned ones. Double-pistoned compressors can handle more significant refrigerant flows and are suitable for larger systems.

How to Choose Bitzer Two Stage Compressors

When purchasing a Bitzer two stage compressor, some features and factors have to be focused on to ensure they fulfill the ultimate purpose.

• Industrial Purpose: Understanding the application is critical to selecting the ideal compressor. There exists a variety of models that fulfill distinct needs. Make sure that the model selected corresponds to the intended use. For instance, a refrigeration compressor might be suitable for cold storage but not for air conditioning.
• Capacity and Power: Consider the cooling needs or workload of the intended application. The capacity is usually measured in tons or kilowatts. Ensure that the selected compressor has a sufficient power rating to handle the required loads. Additionally, pay attention to the energy efficiency of the compressor. Higher efficiency models can lead to significant energy savings over time.
• Operating Conditions: Evaluate the operating conditions of the application, such as temperature ranges and pressure requirements. Some compressors are designed for specific conditions. For instance, open compressors are suitable for low-temperature applications, while semi-hermetic and completely enclosed compressors are ideal for high-temperature applications.
• Control System: Bitzer compressors utilize different control systems to manage their performance and energy consumption. Select a compressor with a control system that matches the application's control requirements. For instance, if precise capacity control is needed, a compressor with an electronic controller might be preferred.
• Compliance and Reliability: Select a two-stage compressor that meets the necessary compliance and regulatory standards. In addition, the durability and reliability of the compressor is crucial for long-term performance and minimal downtime. Research the reputation of the manufacturer and choose a compressor known for its reliability.
