CO2 compressor series have these kinds of models: 4M8, H8, 4M12, 4M16, 4M20, 4M32, 4M22, 6M20, 6M25, 6M40 and 6M22, 6M32, 6M40 etc. Such a compressor can be used as one of the major equipments in various urea processes (the whole solution circulating process, CO2 stripping, NH3 stripping, ACES and IDR etc.) for producing the synthetic ammonia of 133-900 tons per day (40,000-300,000 tons of urea per year). (CO2 flow process for food and cigarette industry)

The CO2 compressor with 4-throws M type adopts 4 stages compression, when its discharge pressure<160 bar. It adopts 5 stages compression, when its discharge pressure>160 bar.

The 4D12, 4D16 and 4D22 type compressors and their spare parts are still produced to meet the needs of the users.

Dalong brand compressor can meet the different needs of the users, such as oil-free lubrication or efficient de-oiling filter will be employed for the compressor according to different processes.
