AMI Penta bio- and fertilizer Mixer

For precise dosing of biomass (bio-fertilizer and beneficials / microorganisms) based on flow of water

By mixing biomass, the addition can irrigate the culture medium at a very precise dosage. AMI Penta controls the irrigation flow so that the software in the mixer allows for different dosing strategies. Exact dosing ensures you control and thus success with your production.

The bio-part (venturi) can be connected to your existing AMI Penta or the function is available in a new mixer equipped with the desired number of bio-venturi. Therefore, the mixer can also function as a common fertilizer mixer with e.g. Ec, but simply with the Bio-program as an extra option. 

Software for all groups, recipes and control of valves are all included in the price - meaning no extra future cost if your needs change.

Easy to operate
AMI Penta fertilizer mixer is easy to operate with well-arranged menus shown on a 10.1” touch screen. Many languages are available and switching between them is very simple. This minimizes the risk and human errors in nurseries employing people of different nationality.

Large capacity and flexibility

AMI Penta can control up to 100 groups with individual start conditions. For each group you can choose between 20 different fertilizer recipes with information about EC, pH and the fertilizer mix. Each group can control up to 30 valves, and these can be chosen freely between the 200 valves available today in the mixer. Up to 9 valves can irrigate at the same time giving a maximal utilization of the capacity. Irrigation time and irrigation volume can be set individually for each valve.

Underlining it’s quality, AMI Penta operates with the very well-known brand GRUNDFOS as the main mixer pump.

Optimizing water resources

To get the same water mix to all valves in the same group, you can mix fresh water sources and return water in ratio percentages. Up to 8 return water basins can be selected with individual control. Thereby the return water is recycled and the water resources optimized.

Modern technology
When you buy an AMI Penta, you get exactly the functions and the functionality you need. The software in AMI Penta is based on a standard operating system and is easy to update and expand with more functions and larger capacity when needed. AMI Penta can be connected to one central PC with the SuperLink central control program for further analysis.

Bio mixer developed in collaboration with customers in Germany and Austria

Two customers with the same need of irrigation with a precise dosing of biomass - and it should be controlled automatically. As there was no fertilizer mixer on the market which was able to do so, they contacted Senmatic. This resulted in an exciting and enriching collaboration - but what was more important was that it also ended up with the development of a bio-mixer that could meet the customer's requirements.
