Product features:
“C”： marine
“D”： low temperature
“SD”： Quick freezing device
Composition: The quick freezing device consists of a compression condensing unit and an end quick freezing device.
The compression condensing unit consists of a marine refrigeration compressor, a marine condenser, an oil separator, a gas-liquid separator, a drying filter, a liquid storage tank, an electrical control box, and a frame. The compression condensing unit equipment is assembled on a frame, greatly reducing the installation workload and space occupation on board, while also facilitating operation.
