This is our Hitachi series semi-hermetic refrigeration compressor. We imported all the production line and technical from Hitachi Japan. This series of compressors are suitable for middle and low temperature cold storage. Compared to our other series compressor, this series compressors are with lower prices but smaller capacity. We totally have four models in this series, ranging from 3HP to 7.5HP. They are more suitable for those projects that are not big and without so much budgets. This one is our smallest compressor. It is 3HP. Below is the detailed information of this model.
