Humidity stabilization - Propadyndustry
Humidity tailored to your needs!

Propadyndustry is a dynamic humidity stabilizer, composed mainly of organic/biodegradable ingredients. Propadyndustry does not eliminate humidity, but rather stabilizes it in order to obtain the right level of moisture depending on what must be protected. There are numerous commercially available products capable of absorbing and eliminating the moisture present in the air. Propadyn is much more.
Propadyndustry controls andstabilizes humidity at the desired level in a gradual manner, without abrupt fluctuations, based on transport or storage needs.
Propadyndustry stands out for its versatility and effectiveness:
- It constantly maintains the desired level of humidity inside closed environments ranging in size from a small box to a shipping container, during transport and storage, even for long periods of time and without any need for electricity.
- It can be used in every type of climate situation: from the desert to the tropics, in places with high or low humidity levels.
- Propadyndustry can be programmed to maintain the desired degree of humidity, between 35 and 80 percent.
Technical characteristics:
- Propadyndustry prevents humidity fluctuations originating from internal or external sources by gradually compensating for the entry or escape of moisture, thus constantly maintaining a stable level of humidity as programmed.
- Propadyndustry rapidly corrects variations in humidity, preventing abrupt fluctuations and constantly maintaining the desired humidity.
- It is highly effective both in absorbing and releasing the desired humidity.
- It is supplied at the desired humidity level.
- It is biocompatible and not harmful since consisting of food ingredients.
- It is available in the following formats: cassette, sheet, strip.
- It requires no pre-conditioning prior to use.
- It does not release liquid and powder during use, which is the most frequent drawback of many dehydrating agents and humidity controllers.
- Propadyndustry is not deliquescent and can therefore be used under all conditions.
- It is extremely versatile and suitable for use in a variety of sectors, including pharmaceuticals, cultural heritage, construction, interior spaces…
- It enables high energy savings in synergy with air conditioning systems.
- Thanks to its chemical composition, it acts as a flame retardant, countering the propagation of fire.
- It is an excellent building insulation material, since it is extremely effective in dampening vibrations (footsteps for example) without modifying shape or geometry (excellent compressibility).
- Propadyndustry is not affected by Volatile Organic Compounds (VOC) and, at the same time, is able to absorb a high amount of these atmospheric VOC.
- Propadyndustry is entirely made in Italy.
- Propadyndustry represents the most advanced, safe and customizable solution for protecting goods vulnerable to humidity fluctuations.
With Propadyndustry humidity is controlled and stabilized…

PROPASEC – Dessicant Clay
Effective, economic and ecological prevention of humidity
PROPASEC desiccant bags represent the most successful and safe solution to reduce the humidity level inside your packaging. Thanks to its absorption capacity, PROPASEC reduces the dew point inside the package allowing to protect the product qualities and properties against humidity attack.
PROPASEC bags allow to transport and stock safely your products for a long time.
PROPASEC desiccant bags are made by a natural mineral material which makes them a safe, environmentally friendly product. Furthermore, Propagroup carefully selects its clays and textiles to guarantee top quality in terms of resistance and high absorption level. PROPASEC range can be supplied in bags, chains or panels according to FDA standard.
Main applications:
- Industrial packaging
- Electronic equipment
- Food packaging
- Medical devices
- Medical diagnostic equipment
- Optical instruments
In case of material produced in accordance with standard DIN 55473:2001-02, the desiccant unit defines the quantity of drying material that absorbs a minimum quantity of 6,0 g of water vapour, at an air temperature of 23±2 ºC and a Relative Humidity of 40%.
Certifications and regulations:
PROPASEC is certified according to DIN, NFH and MIL
PROPASIL - Silica gel
Prevention in any condition
Made from amorphous silica, PROPASIL appears as a hard, semitransparent granular substance. Its moisture-absorbing capacity is very high changing with environmental conditions.
PROPASIL was developed to protect the product from damages caused by moisture. Thanks to its absorption capacity, PROPASIL reduces the dew point inside the packing during shipment, thus preserving its qualities and properties.
PROPASIL micro range is an extremely practical and highly absorbent products. It is the ideal solution for humidity problems in small spaces. Being highly compact it occupies minimal space within the package, while effectively absorbing the residual internal relative humidity.
PROPASIL micro is available in sizes from 0,5 to 3 g.
PROPASIL is available in canisters and in capsules of different weights, certified US DMF and FDA approved. Thanks to their small dimensions they are perfect to absorb the excess humidity in small spaces as inside the containers and vials of medicines or dietary supplements.
PROPASIL range can be supplied in bags, chains or panels according to FDA standard.
Main applications:
- Electronic equipment
- Pharmaceutical products
- Vitamins
- Food packaging
- Medical devices
- Medical diagnostic equipment
- Optical instruments
- Products made of leather, suede etc
- Industrial packaging
PROPADRY - Dessicants for Container
Long protection from humidity
PROPADRY is a revolutionary product line that Propagroup developed to prevent humidity in closed spaces and packages, thus protecting the quality of your goods. It is well known that moisture inside freight containers is one of the main causes of product damage during transportation and storage.
In closed environments, in fact, humidity in the air combined with the one deriving from the evaporation of water contained in the load, virtually tends to create a tropical microclimate that allows infiltration of water vapor into the packages transported.
The result is the creation of condensation that continuously forms and dries, causing irreparable damages. Preventing formation of condensation in containers is fundamental to protect and preserve the quality of your goods.
PROPADRY PLUS 125 gram tray, available in the sizes: 200 x 150 and 300 x 110mm
PROPADRY 125 gram tray, available in the sizes: 200 x 150 and 300 x 110mm
NEW PROPADRY CHAIN: the desiccant chain designed to speed up placing into containers. PROPADRY CHAIN is available in both TRADITIONAL and PLUS versions.
PROPACONTAINER
Condensation is… packed away!
The traditional PROPACONTAINER desiccant pack, 1 kg and 2 kg.
