MICO multistage centrifugal blowers are high pressure units manufactured by SAVIO in Italy since 1945. Thanks to the intermediate stages forming diffusers and return channels, they reach pressures up to approximately 1,100 mBar with flow rates up to approximately 4,800 m³/h. Available in ATEX version up to zone 1/21.
FLUID:
Suitable for clean air and gases, up to +100 °C.
TYPICAL APPLICATIONS:
The ideal solution for biogas conveying and handling, oxygenation in wastewater treatment tanks, process gas recirculation and burner feeding.
Operating Range
The MICO range comprises 4 sizes (90K, 125, 160, 220), each available from 3 to 8 stages: 24 models covering flow rates up to approximately 4,800 m³/h and pressures up to approximately 1,100 mBar, both in compression and suction.
| Size | Stages | Max. flow rate [m³/h] | Max. pressure [mBar] | Max. vacuum [mBar] | Max. power [kW] | Weight [kg] |
|---|---|---|---|---|---|---|
| MICO 90K | 3 – 8 | ~ 1,200 | ~ 850 | ~ 790 | ~ 24 | 75 – 134 |
| MICO 125 | 3 – 8 | ~ 2,200 | ~ 750 | ~ 600 | ~ 65 | 155 – 268 |
| MICO 160 | 3 – 8 | ~ 3,400 | ~ 1,100 | ~ 890 | ~ 120 | 260 – 480 |
| MICO 220 | 3 – 8 | ~ 4,800 | ~ 1,050 | ~ 800 | ~ 190 | 350 – 800 |
Construction
- Central body, intermediate stages (diffusers and return channels) and end plates in aluminium, assembled with tie rods
- Aluminium airfoil impellers, keyed on special steel shaft and statically and dynamically balanced
- Ball and roller bearings in cast iron housings, with automatic elimination of excess grease
- Belt and pulley transmission, belt tensioner on motor base and standard protective guard
- Maximum inlet fluid temperature 100 °C; temperature rise between suction and discharge approximately 50 °C
Special Executions
- ATEX up to zone 1/21 for explosive gases and atmospheres
- Dedicated seals for biogas and technical gases
- High efficiency motors IE3 / IE4 and 60 Hz versions
- Acoustic enclosure with average reduction of approximately 20 dB(A), also for outdoor installation
Biogas and gases with H₂S
General indications on the hydrogen sulfide content in the treated gas:
- up to 5,000 ppm of H₂S: standard ATEX construction
- from 5,000 to 10,000 ppm: anodizing and internal polyurethane coating
- over 10,000 ppm: we recommend treating the gas upstream of the blower
Temperature, humidity, and shutdown cycles affect durability as much as concentration: for every plant, we evaluate the most suitable solution together with you.
Accessories
Single blower/motor base (MICO 125, 160 and 220) · intake filter · silencers · anti-vibration joints on suction and discharge · safety valve for minimum flow · non-return valve · manual butterfly valve · anchoring anti-vibration mounts.
