Ethyleen converter

Storex Catalytic Ethylene Converters (CEC)

Storex has developed a range of highly efficient ethylene converter models. The catalyst used is a special type of platinum. The catalyst does not participate in the chemical reaction, but its presence makes the conversion reaction possible. At a temperature of 250 ºC in the presence of the platinum, a conversion of the ethylene takes place according to the following formula: C2H4 + 3O2, -> 2CO2 + 2H2O.

In the Storex ethylene converter, the cell air is heated to 250C ºC through an efficient process, where the conversion of ethylene takes place. The air is then cooled down to cell temperature as much as possible. For efficient energy management and minimal heating of the cell air, we apply the Energy Swing principle whereby the airflow passes the reactor with alternating airflow direction. The process is designed based on our strict principles of using large diameter piping and valves and variable speed fans.

ENERGY EFFICIENT – HIGH CAPACITY

Efficient conversion of ethylene present
Excellent protection against unwanted fruit ripening
Energy efficient through the use of large diameter valves and pipes, variable speed direct drive fans, temperature sensors and smart process control
Easy to operate, remote control provided
Gas-tight design for CA storage
Low energy consumption due to efficient heat retention (Energy Swing principle)
Due to the principle of catalytic conversion, no renewal of filter material is necessary
The high temperature shock of 250°C kills spores of mold and bacteria present in the air

C2H4 – Ethylene removal during fruit storage

Fruit produces ethylene during storage. Ethylene is an important plant hormone that stimulates ripening and has a direct effect on the firmness of sensitive fruits. During the storage season, both the ethylene production and the sensitivity of the product may be increased. This can lead to an unwanted early ripening.

Some fungi also produce ethylene. Both Botrytis cinerea and Penicillium digitatum mycelium have been found to produce ethylene at very low levels.

For kiwis, it is very important for fruit quality and shelf life that these fruits are stored under conditions with very low ethylene levels. A maximum level of 20 ppb ethylene is recommended.

Other products in (CA) storage may also respond positively to ethylene removal.
Storex offers both catalytic ethylene converter and ethylene adsorbers for ethylene removal.
