Conviron's SR Series seed storage rooms are based on a modular platform. These seed storage rooms are custom sized for each application and are suitable for both long term and medium term collections. Long term seed storage conditions are typically set to minus 18 degrees C while medium term collections are stored at 4 degrees C and 30 to 50% RH. Dehumidification is provided using a chemical dehumidifier. Several different cooling methods are available while complete mechanical system redundancy is also available where required.
