    LBII-PLUS series semi-hermetic screw refrigeration compressor

    In recent years, Hanbell has launched LB, LB-PLUS series low temperature screw refrigeration compressor based on the integrated application experience in low temperature field and customer demand. In order to further expand the application field and reliability of products, LBII-PLUS series compressors are specially developed. LBII-PLUS series compressors continue to use the automatic control function of LB-PLUS. On the premise of ensuring intelligent application, LBII-PLUS series further optimize the motor cooling control logic and cooling structure, improve the safety margin of LBII-PLUS, and further expand the operation range, so that LBII-PLUS can meet the application requirements of air-cooled system. At the same time, it further improves the performance, so that LBII-PLUS can be widely used in refrigeration, industrial process cooling, freeze-drying and other fields with sufficient competitiveness. In general, LBII-PLUS is a new elite product of Hanbell in the low temperature application field.

    Features
    Model Specification

    Electronic expansion valve

    The LBII-PLUS adopts electronic expansion valve. Its precise control, stability in operation and simplification control make compressors simpler, safer and more reliable.

     

    Independent cooling of motor

    It ensures that the motor runs at the ideal temperature, which effectively prolongs the life-time of the motor. The harmful superheating of the suction refrigerant will no longer been increased. The refrigerant after cooling the motor enters the compression chamber, so it will not cause the cooling loss due to the cooling of motor, which achieves a higher energy efficiency ratio, especially in the low temperature application.

     

    Application design of single compressor and parallel connection

    LBII-100~280-PLUS are divided into two structural forms: with oil separator and without oil separator. LBII-360~410-PLUS have only one structure without oil separator. It can be applied to various application fields, and different suction and discharge outlet directions can be selected.

     

    High efficiency multistage oil separator

    Patented segmented high efficiency oil separator design ensures the lowest oil loss rate during the compressor operation.

     

    Optimization of motor cooling

    The motor cooling control logic of LBII is optimized and operation range is expanded to meet the requirements of air-cooling applications.

     

    Optimization of economizer connector

    The connector of economizer is optimized, and the performance of LBII-PLUS with economizer is improved compared with LB-PLUS.
