Caravans Silica Gel Manufacturers

This caravans silica gel is a moisture-proof and dehumidifying product designed specifically for caravans (travel trailers, campers,etc.). It can effectively control the humidity in the caravans, preventing mold growth, rust on metal parts, and mildew on the interior. This desiccant can ensure that your caravans maintains a dry and comfortable environment while parked or traveling.

Noted: We can custom silica gel desiccant for specific application.

Moisture Absorption Capacity

Under standard conditions of 25℃ and 80% relative humidity, its moisture absorption rate can reach 28%-32% of its own weight. In a closed caravans environment (about 5m³space), 100 grams of caravans silica gel can absorb about 30 grams of water vapor in 24 hours, reducing the relative humidity from 80% to below 50%.

This desiccant maintains a stable moisture absorption efficiency in the humidity range of 20%-90%. Even at a low temperature of -40℃ or a high temperature of 120℃, it can still maintain a moisture absorption capacity of more than 85%. According to our tests, a 500-gram desiccant can work effectively for 30-45 days (depending on the ambient humidity) in a standard caravans environment (10m³). After saturation, it can be completely regenerated by heating at 110℃ for 1-2 hours.

Product Features

1. This caravans silica gel can quickly absorb moisture inside the caravans, and prevent condensation from accumulating. Therefore, it can protect the furniture, electronic equipment and clothing from moisture.

2. It can inhibit mold and odor. Therefore, it is particularly suitable for closed caravans spaces to keep the air fresh.

3. Non-toxic and odorless. It does not contain corrosive ingredients. It complies with RoHS standards, so it is suitable for long-term use in closed environments.

4. Strong temperature resistance. It adapts to the use needs of caravans in different climates. And it can still work stably in high temperature (such as summer exposure) or low temperature environments.

5. Renewable and reusable. Cost-saving solutions.

6. A variety of packaging specifications (bags, cans or hanging). It is convenient for placement in different moisture-prone areas.

Applications

Our caravans silica gel is widely used in various types of caravans, including but not limited to the following types:

Caravans Types	Recommended Use
Motorhomes	Place 50g~100g desiccant bags in bedrooms, kitchens, and bathrooms.
Travel Trailers	Place desiccants in lockers and under beds, paying special attention to protecting tires and mechanical parts.
Pop-up Campers	Place a 10g~20g desiccant packet on the folded area before storage.
Off-Road Caravans	Use large capacity (500g) canned desiccant and ventilate system.
Campervans)	Hang breathable bagged desiccant under seats and in the trunk.

Our caravans silica gel is very suitable for seasonal parking, use in high humidity areas, and winter condensation prevention. In addition, we can customize the most effective moisture-proof solution according to different application scenarios.
