Managing CO2 levels in potato stores is mainly done with large, energy-hungry fans. By not using your large fans but instead using a small Restrain CO2 extractor, you can save one and a half hours of run time of the large fans every 24 hours, according to a news release issued by Restrain company.

How does it work?
Place the extraction tube low to the ground, where the highest CO2 content is. When it detects a carbon dioxide concentration above the level selected by the store manager, the extractor starts up and flushes CO2-rich air from the store. Extraction continues until the desired concentration is achieved. When the CO2 content in the air increases, extraction starts again.

Less weight loss and better frying color
By automatically managing the CO2 content by extracting only small volumes of carbon dioxide-rich air, you reduce fluctuations in store temperature and humidity. This way, you ensure potatoes with less weight loss and a better fry color.

Calculate savings with the energy calculator 
Store managers can simply enter crop and storage information online, and within 30 seconds, the Restrain Energy Calculator will calculate how much can be saved monthly. Access the calculator here:
