Mapro International Installs Centrifugal Blowers in Thailand

Instead of anerobic digester mixing propellers, MAPRO RF Rotary Vane Compressors were chosen to inject 100 m3/h at 1.3 bar (60 CFM at 18.6 PSI) recirculating air/gas. When mixing digester liquor through a more uniform distribution of flow into blind areas a propeller does not reach, this results in lower energy consumption, lower maintenance, higher reliability, lower corrosion, and better system efficiency.

The MAPRO CM multistage Centrifugal Blowers were chosen over PD Blower technology to feed 2200 m3/h at 250 mbar (1294 CFM at 3.6 PSI) gas motors. This resulted in lower maintenance, easy access to seal replacement, fewer spare parts required, higher flow flexibility, forced ventilation on the electric motor not required, no sparking materials, higher tolerance on handling condensates, higher reliability due to Aluminum impellers, and low risk of seizure. Anticorrosive treatments are also available.
