Latest Airixa Install Brings Modernized Control Systems to Two Avocado Processing and Storage Facilities in Mexico

If you purchased an Avocado this year with a sticker on it proclaiming, “Produce of California” or “Produce of Mexico,” there is a good chance it came from a ripening facility being run by an Airixa energy management and refrigeration system.

Recently, Process Solutions sent engineers to Mexico to begin work on commissioning new Airixa control systems to be installed in two separate Avocado processing and storage facilities.

The first facility was stocked with millions of dollars worth of produce when we arrived, which meant the customer could not afford to have the system down for a longer than 3 hours. Fortunately, we were aware of the situation before arriving and took steps to create wiring harnesses with mating connectors that plugged into the existing connectors left behind after removing the legacy control system. These plug and play harnesses allowed us to keep facility downtime minimal and install the entire system in one day.

During the installation, our engineers discovered that Airixa, with its Siemens S7-1517 PLC, 4 ET200SP racks, and highly optimized custom software package, was so powerful that it was able to replace and outperform all 11 of the existing control units. This created a highly efficient system with a significantly smaller footprint.

In addition to the PLC components, the Airixa system at this facility also included a combination of 67 variable frequency drives, 7 RTU to Modbus converters, and a fiber-optic cable to connect the system between two remote locations at the facility.

Once installation was complete, Airixa began operating 2 separate engine rooms with 7 refrigeration compressors, 6 condensers, 10 suction accumulators, and 2 Freon detectors, along with 15 cooler rooms housing 57 evaporators.

The second Airixa system we installed in Mexico was considerably smaller than the installation at the previous facility; however, it still led to a transformation in the customer’s production processes and helped significantly boost efficiency. After replacing the existing legacy control units, Airixa took over operation of the facility’s engine room, which included a chiller and glycol circuit, along with 3 refrigeration compressors, 5 condensers, and 4 cooler rooms with 14 air units. In order to run the facility’s equipment, this Airixa system was equipped with 30 Siemens G120 series VFDs.

Airixa is a technology platform for the control of industrial refrigeration systems and energy management. With Airixa, companies can reduce peak energy demands and run their facility at optimal efficiency without sacrificing operational performance.
