Description and use (according to manufacturer)

Propadyn is a passive humidity controller, able to stabilize humidity levels in confined spaces, from small boxes to shipping containers, during exhibition, transport and storage.


Propadyn is the best solution to move and store goods vulnerable to humidity fluctuations, such as fruit, vegetables, chemical products, art works, coffee, tobacco and many more. Additionally, Propadyn is designed to stabilise the climatic conditions in all spaces subject to humidity level changes, such as camping tents, gyms, boats, etc..

Propadyn does not need activation and does not require electricity: it is provided ready to use and can maintain constant relative humidity levels between RH = 30% and RH = 80%.

Propadyn is a safe and biocompatible product, because each of its ingredients is natural and comes from the food sector.

Physical and chemical properties

Its capacity to stabilize humidity is represented by the value M, defined as the amount of water (in grams) that 1 kg of controller absorbs or releases when relative humidity increases or decreases by 1%. A high M value indicates high capacity of regulating humidity.

As the controller’s capacity of absorbing water varies with the level of humidity, M is calculated for each humidity range of interest. The table below shows the values of M that characterise Propadyn’s excellent performances: (Our comment: we think that M-values should be indicated for every % RH and not only for intervals of 10 % RH - this might lead to wrong conclusions...)

   

Dimensions and weight

Propadyn is provided, depending on the requirements, at a specific humidity level i between 30% and 80% RH, in the following dimensions:

  • Propadyn 3200:
    300 x 115 x 12 mm box containing 200 g of active material *
  • Propadyn 3400:
    300 x 115 x 24 mm box containing 400 g of active material *

* Weight reference RH = 45%


The boxes have a rigid polypropylene structure and a permeable fabric to allow exchange of moisture with the surrounding air.

Use

Propadyn does not require pre-conditioning and starts working as soon as it is taken out of its protective packaging. Therefore, we recommend it to be placed in the position in which it will be used as soon as possible after being opened.

According to the manufacturer Propadyn 3400 can stabilise approximately up to 1 m³ of air, depending on ambient conditions and the type of use (ventilation, external climatic fluctuations, allowable tolerance, etc.).

Propadyn was designed and developed to be reusable. Once its capacity to control moisture is exhausted, through a regenerating treatment designed by Propagroup, it can be brought back to its original RH level, completely restoring its characteristics.

Technical Data

  • Humidity controlling capacity: between RH 30% and RH 80%
  • Tolerance: ± 3% RH
  • Density (active material): 1,1 – 1,5 g/cm³

Packaging

Each box of Propadyn is wrapped in a protective packaging with laminated barrier film, keeping the product’s characteristics unaltered until the time of use.

Warning

To avoid alterations of the product, the manufacturer recommends avoiding immersing Propadyn in water or water solutions, as halide solutions could be released.
