Bitzer Semi-Hermetic Compressor

Bitzer is a well known manufacturer of Semi-Hermetic Compressors for a wide range of applications in refrigeration and air conditioning systems. Semi-hermetic compressor compressors integrate the motor and compressor in a single shell, but unlike the fully hermetic type, they have a removable top cover that allows maintenance or repair of the internal components.

DIVERSITY OF EXPLORATION

OUTDOOR SCENE

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
