Extraetil, molecular sieve for the ethylene absorption

Extraetil, molecular sieve for the ethylene absorption

EXTRAETIL by BRANCATO is a granulous product absolutely ecological, with a macroreticular and microporous structure and an extraordinary capacity of absorption of ethylene.

EXTRAETIL was studied and tested in our laboratories and its capacity of absorption is on the average from 2 to 4 times higher, under the same weight, than the other similar reactive substances which exploit the same principle, that is KMnO4 (potassium permanganate). Our firm produces and sells EXTRAETIL at a very profitable cost.

EXTRAETIL has the following advantages:
- It is characterized by a high degree of porosity, active surface of exchange 60/70 sqm/g
- The purification action of ethylene is performed not only outside the surface of the granule surface, but even inside the volume of the pores
- The absorption capacity ranges from 3.5 gr to 4.0 gr of ethylene/kg of EXTRAETIL, used with our absorber BK/3
- It also eliminates some harmful gases such as hydrocarbons, and same toxic once such as S02. Density 1070/1020 g/l(according to the granulometry)
- Air filtering by means of EXTRAETIL with our absorber "BK/3" keeps the ethylene concentration near 0 (change the product in time)
- Granules, when absorb ethylene, oxidize and develop CO2 and H2O and turns its color from violet into brown
- To be sure that some active principle still remains, take some granules out and pour them in a small cup full of water: if the water gets violet, the principles are still active
- EXTRAETIL is supplied in cartridges containing 14 kg of product
- They are made in such a way as to be inserted inside our BK/3, or in 10 kg or 50 kg containers to be used in other machines, too
- Moreover, EXTRAETIL is supplied in mattresses of about kg 2, (cm. 70 length), that can be used in cupboards, containers or small cool-rooms for fruits and flowers
