Ethylene gas system for processing potatoes

Experience the Restrain ethylene gas system for your potato storage — an innovative sprout control solution using a generator placed directly in your store. Our novel (patent-pending) startup procedure ensures fry color is preserved. With no harvest interval and no need to exclude personnel from the store, Restrain simplifies crop management. Fully approved and residue-free, Restrain keeps your store and crops clean, safe, and efficient.

Key benefits of ethylene gas

How it works

Treatment is continuous

The Restrain generator continuously distributes a low concentration of natural ethylene gas evenly throughout the store. Restrain is suitable for organic farming and leaves no residue.

Effective after 3 days

After three days of exposure to ethylene, the sprouting process of potatoes is suppressed. It is safe to be in and around the storage during treatments.

Sensor measures ethylene concentration

The sensor measures the temperature, relative humidity, CO2 and ethylene concentration in the store and automatically adjusts the ethylene production.
