What is the operating voltage of the Grain Cooler?

The standard operating voltage is 380V/50HZ (3PH), but it can be customized.

What types of grains can be stored using this system?

It is suitable for rice, maize, wheat, barley, soybeans, sunflower seeds, sorghum, cotton seeds, green coffee beans, and feed pellets.

How does the cooling process work in a silo?

Cold air is introduced at the bottom, pushing heat upwards through the grain mass until the exhaust air is cold, forming a cooling zone.
