This patented product features a unique membrane that promotes moisture entry into the tank but prevents it from escaping. This allows harmful moisture to be removed and prevents water that has been absorbed into the tank from escaping.
SaniDry Tray is suitable for rooms up to 30 m3 and SaniDry Tray Grande up to 60 m3 for approximately three months. Recommendations may vary depending on temperature and humidity.
The SaniDry Dehumidifier absorbs moisture from the air efficiently, safely and cleanly. It also minimizes the risks of direct contact and accidental water leakage. (It is not a problem if the product falls over, as moisture penetrates the membrane from the outside to the inside, but the absorbed moisture can no longer escape.)
The product starts absorbing moisture as soon as it is taken out of the packaging. It is ready to use immediately, without the waiting time usually required when using this type of product.
Removes excess moisture in many different applications: for example, excess moisture caused by rain or snow or brought in by a dog in a car, caravan, boat, home, garage, basement, summer cottage, house foundations or when camping.
SaniDry also reduces the growth of mold and prevents musty odors. It effectively prevents mold growth in refrigerators on boats or caravans, for example. The product also removes unpleasant musty odors very effectively.
- Size 250gr
- Coverage for 30m2 space
- Equipped with a unique membrane: prevents moisture from returning to the space from which it is desired to remove moisture.
- Very good absorbency.
- Does not leak when spilled
- Prevents mold growth
- Prevents musty odors
- Available in two sizes
- Easy to use – the product is ready to use right out of the box
- You can start using the product as soon as you remove the outer packaging.
- Patented and manufactured in Europe
- Recyclable packaging

The dry ball effectively absorbs excessive moisture and condensation, which cause mold damage and bad odors. Removing moisture and condensation also reduces the energy needed for heating in a holiday home. Used in holiday homes, caravans, boats, garages, basements, bathrooms, laundry and storage rooms or similar moisture-sensitive rooms. One refill bag is enough for 1-3 months depending on the amount of moisture and temperature and is suitable for a space of approximately 12-14m2. Avoid direct contact with metal. Rinse with lukewarm water if necessary. When the mesh bag is empty and the jar is full of liquid, the container is emptied into the drain. Add the contents of the separately purchased refill bag and the dry ball is ready for use again.
How to use
Torrbollen Original consists of three plastic parts and one dehumidifier bag. Assemble the product as follows: first place the flat lid part on the bottom part, and on top of it the dehumidifier bag, which has been removed from the plastic. Then place the perforated top part in place.
The bag absorbs moisture from the air, and the collected liquid drains into the bottom of the Torrbollen. The liquid should only be poured out when the container starts to fill up. The liquid is environmentally friendly and can be poured into the drain.
IN THE PACKAGE:
- 1 x dry ball
- 1 x refill pack
- Refills can be purchased separately
- Size: 450g
- Enough for 1-3 months of dehumidification
- For a space of 12-14m2
- Non-toxic
- Stops moisture, mold and bad odors

For spaces over 20m3, e.g. summer cottages. Works for 2 - 5 months/filling. The dry ball holds 3 filling bags.
Torrbollen Mega Dry Ball is designed to reduce humidity levels in enclosed spaces with little or no ventilation. Torrbollen effectively removes excess moisture and reduces the formation of mold and unpleasant odors. Mold can often cause allergy symptoms. It is ideal for use in winter storage of boats and caravans. It can also be used in holiday homes, basements, cellars, bathrooms, storage rooms, garages, storerooms, stables, changing rooms or similar moisture-sensitive rooms.
How long does Torrbollen's effect last?
It depends entirely on how humid the space is. Generally speaking, one refill bag will last 1-3 months in a 12-14 m² space.
How does Torrbollen work when the temperature drops below zero?
Torrbollen always works down to zero degrees, but when there is no moisture in the air, it stops working. The liquid in the jar does not freeze.
What to do if liquid spills on the floor or carpet, for example?
Dry and wash with warm water. Repeat if necessary.
Where do you pour the liquid when changing the filling bag?
Pour the liquid into the drain. This does not pose an environmental risk. Avoid contact of the liquid with metal as there is a risk of rust formation if it is not rinsed.
Why does a non-woven bag sometimes harden?
When the flakes in the non-woven bag are saturated with water and the moisture in the space runs out, they harden and dry together, making the bag hard. When the moisture returns, the process starts again, albeit with a slightly reduced efficiency, as the surface area of ??the flakes has decreased.
- For spaces over 20m3
- Works for 2-5 months
- Capacity: 3 x 450g

Three different sized refill packs available:
- 1 pc 450g refill pack
- 3 pcs 450g refill pack

Red Line diesel additives lubricate pumps and injectors. They clean the fuel system. They reduce exhaust fumes. They improve engine performance. They reduce wear in the fuel system.
Red Line diesel additives provide lubrication to the fuel while effectively cleaning the entire fuel and combustion system. This results in the engine running better and delivering more power. The improved lubricating properties of the fuel reduce wear on diesel pumps and injectors. Today's diesels are "rougher, drier" than in the past. In addition, fuel and engine oil form deposits. This generally results in poorer engine performance, increased fuel consumption and worse exhaust emissions.
- Cleans the fuel system
- Improves engine performance

Red Line SI-1 additive prevents sparking of glow plugs. It cleans the carburetor and injector. It prevents rust in the fuel system. It stabilizes the fuel during long-term storage. The current quality of gasoline, together with engine oil, forms deposits in the fuel system, which can manifest as starting difficulties, uneven running and increased fuel consumption.
Red Line gasoline additive is unique because it effectively removes deposits and lubricates the fuel system, but also because it stabilizes gasoline during long-term storage (such as off-season storage). SI-1 can be used in both 2-stroke and 4-stroke engines.
- Cleans carburetors and injectors
- For 2-stroke and 4-stroke engines
