CalCA knows the secret: strictly controlled storage.
Produce-specific oxygen, nitrogen, and carbon dioxide levels plus temperature and humidity controls keep apples, peaches, grapes, and other fruits and vegetables in peak condition before they reach your table.
Between farm and market
Central California farmers produce the bulk of the nation's fruits and vegetables. And employee-owned California Controlled Atmosphere (CalCA) in Dinuba, California, is widely recognized as the area's leader in industrial refrigeration services.
CalCA looked for a flexible and scalable control system with a long operational life.
Changing harvests demand a reliable control system that can scale up and down as needed.
A third-generation farmer and pomologist, Doug Gerdts knows fruit. He also knows control programming.
"With Opto 22 we’ve been able to maintain systems for a long period of time," says Gerdts. "The I/O is very hardy. We’re able to do most of our controls directly through the output modules without any interposing relays."
