| Spagnol MCI 500 is an open mixing-tank fertigation computer. It can be used where there are high flow-rates and a request for precision dosing. The management features are the same as in the MCI 300. |

The MCI 500 is a fertigation computer with open mixing tank. It can work with flow-rates that go from 4 to 140 m2/h and dose concentrate solutions on the basis of total conductivity or volumetric ratio in ml for every litre of fresh water.
The hardware components of the MCI 500 are modular and expandable. In this way it can satisfy any request for nutrient solution, drainage and fresh water sourcing management.
Moreover, the MCI 500 can manage nebulization, misting and fog systems on the basis of climatic parameters inside and outside the greenhouse.
The MCI 500 can also manage greenhouse microclimate control systems like cooling vents and heating systems. It can be equipped with a meteorological station to continuously monitor climatic parameters.
The most important technical features of the MCI 500 are:
- double electrical conductivity measurement and regulation through temperature compensation
- double pH measurement and regulation through temperature compensation
- dosage of 8 concentrate solutions through total electrical conductivity or volumetric ratio concentrate solution/flow-rate of irrigation system
- aspiration of 2 acid solutions
- possibility to command from 1 to 144 solenoid valves with 24 independent fertigation programmes
- irrigation system flow-rates up to 60 m2/h (even zones with different flow-rates)
- nutrient solution dosage by time or volume (minutes or hectolitres of nutrient solution).
It is also possible to connect:
- a photoradiometer to start irrigation on the basis of solar radiation
- Drenamatic drainage probes for management of irrigation on the basis of drainage (very useful for irrigation management in soil-less crops)
- Scalematic for irrigation management on the basis of the weight of the substrate
- accessories that will automatically start irrigation, like tensiometers, Wet sensors, scales, etc.
- accessories for connection with sub-irrigation systems like ebb & flood systems or other nutrient solution recirculating systems
- hardware/software accessories for management of water sources like wells, catch basins or drainage
- inverters to regulate the pressure of each solenoid valve
- solenoid valves or other devices for automatic counter-washing of filters.
The MCI 500 has an internal memory for the filing of data regarding irrigation, alarms and climate.
An alarm programme intervenes in case of anomalies to the system inside or outside the greenhouse therefore protecting the crops and immediately informing the operator with messages on the monitor.
The MCI 500 can be connected to MC-Net 4 for long-distance supervision and to Process C1 for interaction with climate parameters.
