BP6 - Replace refrigeration compressor

Company name: MINH DANG Co., Ltd
Address: 83 Provincial Road 8, My Xuyen Town, My Xuyen District, Soc Trang Province
Project Summary: Replacement of piston refrigeration compressors with screw refrigeration compressors. The project targets to reduce the energy costs and the emission of greenhouse gases.
Year of implementation: 2017

Status before implementation

Minh Dang Co., Ltd. produces frozen seafood for export with main products including: squid, octopus. The factory has 2 continuous refrigeration systems for cold storage, IQF conveyor, and re-freezing.

In order to save the energy, the plant was planning to replace 4 existing reciprocating compressors with 2 high-efficient screw refrigeration compressors.

                           

          Existing reciprocating compressors                      

Result

The plant has replaced 4 reciprocating refrigeration compressors with 2 high-efficient screw compressors. Total power consumption for the refrigeration systems reduced by 30.6% 298 tons of CO2/ year have been be reduced.
