MOISTURE STABILIZERS

Humidity fluctuations cause products to deteriorate, whether in food, industrial products or cultural goods. Moisture stabilizers allow you to maintain humidity in a certain range.

Moisture stabilizers are ideal for maintaining relative humidity in a specific humidity range to avoid deterioration in products. They are able to achieve this since, when the humidity rises above a certain threshold, they react quickly by absorbing water vapor from the environment. Similarly, when the relative humidity drops below the threshold, they release water vapor into the environment to increase the relative humidity value.

Moisture stabilizers can be used in all those closed spaces in which you want to keep humidity at a specific value: conservation of works of art, food industry, pharmaceutical industry, military industry, etc.
At Sercalia we offer different types of humidity stabilizers that cover different needs (different ranges of relative humidity). You can consult them below.
Moisture absorber. Propadyn Museart. Control humidity. Sercalia

Propadyn Museart

The moisture stabilizer PROPADYN Museart allows you to control humidity by keeping it at a certain desired value to protect and safeguard works of art from deterioration. Faced with a rise in humidity, the product reduces it by reacting quickly. In the opposite case, when the humidity has dropped, it is able to release humidity to leave it at the desired value.

Humidity stabilizer. Dehumidifier. Propadyndustry. Sercalia

Propadyndustry

Changes in humidity cause deterioration in many products, both in food, industry or cultural goods. The Propadyndustry moisture stabilizer achieves control at a specific value.

Prosorb. Moisture stabiliser. Sercalia

Prosorb

The Prosorb moisture stabilizer allows you to control humidity by keeping it at a certain desired value between 30 and 60% relative humidity. Due to its large internal surface and its ability to absorb and release water vapor from the environment, Prosorb can maintain a stable relative humidity.

Artsorb. Sercalia. Moisture stabiliser

Artsorb

Artsorb Moisture Stabilizers allow you to control relative humidity by keeping it at a desired value between 65 and 75% (or 50% using the stabilizer sheets). Due to its large internal surface and the ability to absorb and emanate water vapor from the environment, Artsorb is able to maintain a stable high relative humidity. It also contains lithium chloride as an additive that allows it to reduce humidity in environments with higher values.

FAQs

How moisture stabilisers work and why they are key to maintaining stable conditions

What problems can a lack of humidity control cause in sealed products and spaces?

Sudden changes in humidity or incorrect levels can cause materials to shrink or warp, metal components to corrode, mould to grow, food or pharmaceutical properties to change, and even damage to works of art and heritage items. Humidity stabilisers maintain relative humidity within an optimal range, preventing these types of degradation.

What types of humidity stabilisers does Sercalia offer?

Sercalia offers you an extensive range of humidity stabilisers, including:

  • Relative humidity control cassettes and panels
  • Absorbent bags or sachets and bulk products capable of releasing or retaining vapour as required.
  • Systems for display cases, archives, and shipping containers that regulate humidity in both directions.
  • Special solutions for specific relative humidity ranges (30–60%, 50–75%). Each format is tailored to different sectors and technical requirements.

Discover above the specialized brands we offer in humidity stabilizers, with formats adapted for showcases, archives, packaging, and industrial containers.

How do I choose the most suitable humidity stabiliser for my application?

The selection depends on factors such as the volume of the space, the desired humidity range, the duration of the storage or transit period, and the type of product (heritage, industrial, food or pharmaceutical). At Sercalia, we carry out a technical analysis to determine the appropriate range, the type of system (absorbing or releasing) and the optimal format according to your needs.

What is the difference between the various grades and formats of moisture stabilisers?

The key differences lie in the range of relative humidity they maintain (e.g. 30–60% RH versus 50–75% RH), the physical format (cassette, bag, panel), and the capacity to absorb or release vapour. For example, a high-capacity cassette works for large chambers or museums, while a bag may be sufficient for a container or cabinet.

What solutions does Sercalia offer for large volumes or long-distance transport?

For international shipments, storage chambers or shipping containers, Sercalia offers humidity stabilisers with high regulation capacity, modular systems capable of absorbing and emitting vapour according to environmental variations, maintaining stable relative humidity for days or weeks without manual intervention.

Can I combine humidity stabilisers with other environmental protection systems?

Yes. In many applications, humidity stabilisers are combined with moisture absorbers, oxygen absorbers, temperature control or vapour barriers. This combination allows for comprehensive control of critical factors—humidity, oxygen, temperature—and increases the reliability of the preservation or transport process.

In which sectors is the use of humidity stabilisers recommended?

Humidity stabilisers are particularly relevant in:

  1. Art and heritage conservation (display cases, archives).
  2. Food and logistics (warehouses, transport of dry goods).
  3. Pharmaceutical (sensitive packaging, stability chambers).
  4. Electronics and automotive (components susceptible to moisture).

Each sector has specific conditions that Sercalia understands and addresses technically.

Are humidity stabilisers safe for food or pharmaceutical use?

Yes. Most Sercalia products are designed with inert materials that are safe for indirect contact with food or pharmaceutical products and comply with international regulations that guarantee their suitability, without affecting the quality or safety of the product.

How long does a moisture stabiliser remain effective?

The duration depends on the format, environmental conditions, and level of sealing of the space. A properly sized stabiliser can maintain the desired humidity level for weeks or even months. For continuous and critical control, we recommend monitoring or replacement according to the manufacturer’s technical data sheet.
