Ethylene Control

Ethylene management in flower bulbs is crucial. Ethylene can seriously affect the development and quality of flower bulbs, leading to loss of color, shape and vitality.

During the storage of tulip bulbs, so-called 'sour bulbs' (affected by the Fusarium fungus) produce ethylene. This gas has harmful effects on healthy bulbs: ethylene causes excessive knotting in planting material and flower desiccation in available bulbs.

Effective ethylene management can improve the lifespan and quality of flower bulbs. The Besseling ethylene converter removes the ethylene gas quickly and easily. This way your product retains eternal youth.

The ethylene converter consists of two columns, each with a heat storage medium, a catalyst, heating elements and one fan. Cold room air is led up and heated alternately per column. The air is then led through the catalyst bed where the ethylene gas is broken down. Finally, the air flow is led through the second catalyst bed, where the remaining ethylene is broken down and the air is cooled again.

With the Besseling ethylene converter, an ethylene level of 1 ppb (0.0000001%) can be achieved without the use of chemicals. This makes this process extremely environmentally friendly. By recovering heat and accurately controlling the optimal temperature, the converter consumes minimal energy.
