Low Temperature Screw Compressor

Core Advantages:

1. Electronic Expansion Valve

The LBI1-PLUS model utilizes an electronic expansion valve, providing precise temperature control and highly stable operation. This design simplifies compressor control, enhancing safety and ensuring long-term stability and reliability.

2. Independent Cooling

This design ensures the motor operates at optimal temperatures, effectively preventing refrigerant overheating caused by motor cooling. The cooled refrigerant enters the compression chamber, further improving energy efficiency, especially suitable for low-temperature applications, ensuring efficient system operation.

3. Single and Parallel Compressor Design

The LBI1-PLUS series compressors offer both single and parallel compressor design options, supporting various structural configurations to meet different application needs. This flexibility allows the compressor to adapt to various suction and discharge port directions, meeting diverse installation requirements.

4. Electrical Insulation

The LBI1 series Low Temperature Screw Compressor features optimized electrical wiring, positioned away from the suction port to reduce frosting and improve electrical safety. Compared to traditional low-temperature screw compressors, this design significantly enhances equipment safety and long-term operational reliability.

5. Multi-Stage Oil Separation Design

The LBI1-PLUS adopts a multi-stage high-efficiency oil separation design, reducing oil carryover during compressor operation, further improving refrigeration efficiency and reducing environmental pollution, ensuring efficient and continuous operation.

6. Optimized Motor Cooling

The LBI1 series optimizes the motor cooling control logic, broadening the operating range and allowing it to adapt to a wider range of air-cooled applications, improving compressor operational stability.

7. Optimized Economizer Interface

The economizer interface design has been optimized, resulting in a significant performance improvement with the economizer compared to the LB-PLUS series compressors. This improvement allows the LBI1-PLUS to more efficiently support low-temperature conditions, enhancing overall system energy efficiency.
