Desiccant use at home, warehouse or boat.

Advice on solving humidity problems

Excess humidity at home can cause the appearance of mould, mildew, fungus and all kinds of nastiness that endangers your and your family’s health.

In order to solve the humidity problems in a room, bathroom, store room, etc. first of all you need to find out the cause of the excess humidity:

If the humidity comes from outside, caused by a leak or by defective insulation, our products will help to reduce the level of ambient humidity, but will not solve the problem for good. The best thing to do is to consult an insulation specialist so as to solve the root of the problem.

If the problem is due to excess ambient humidity in the room because of poor ventilation or condensation, our product can solve your problems.

How does it work?

Put the product anywhere in the room and leave it to work. The desiccant will activate automatically, absorbing the excess humidity. Once the desiccant has stopped absorbing, put in a refill. How long the product lasts depends on the temperature and level of humidity in the room.

It works without electricity or batteries.

Nordic Power Desiccant regulates the level of ambient humidity to bring it down to the recommended optimum level of 45-50%, without drying out the atmosphere, absorbing only the excess humidity.

Is it toxic? Can I use it in a child’s bedroom?

All Nordic products are non-toxic. They can be used without any problem in any room in the house, whether inside a wardrobe, in bathrooms or in store rooms – even in bedrooms. They are also very popular for use on a boat or yacht.

The desiccant contained in the product is calcium chloride, hygroscopic salts which are non-toxic and environmentally friendly.

Finding and Identifying Basement Mold


Basement mould is a term refers to the types of fungus that grow in basements under certain conditions. Basement mould is harmless in small quantities, but as it grow, it becomes more and more of a health hazard. Some will cause certain types of allergic reactions while others are outright poisonous. If left untreated, the basement mould will keep growing, eventually spreading through the entire building. This is why you must find the mold before the problem gets out of hand. Once you find it, you will need to be able to identify it—otherwise, you won’t be able to figure out how to get rid of it.

Finding Basement Mould

One of the easiest ways to identify the mould is by it’s stench. However, this is only true for some types of basement mould, others may not start to smell until their growth reaches a certain stage. That is why you may want to take a more proactive approach and check the spots where the mould is most likely to emerge. That way, you will have a better chance of spotting it while it is still at manageable size.

Basement mould needs a wet environment in order to grow. It will grow near the pipes and along the walls. The mould feeds on common household materials such as plywood, drywall, furring strips and carpet padding, as well as dust and cellulose in carpets themselves. Try to check any parts of the basement that are hospitable to mould at least once every week. Be sure to bring a flashlight with you—you may not be able to get adequate illumination without it.

If your basement suffers any sort of flooding, the walls will become infested with mould spores, which will remain dormant until they come in contact with water. The spores can remain dormant for a long time. Just because the mould didn’t develop after the flood doesn’t mean it won’t become an issue several years down the line.

Mould Safety

If you find a patch of mould, try not to inhale too deeply and don’t touch the mould with any part of your body. If it gets on your clothing or your tools, wash it immediately. You can identify the mould by sight, so there is no reason why you should be touching the mould in the first place.

Identifying Basement Moulds

Basement mould can be identified based on a number of factors. First, there is colour. Basement mould comes in a variety of colours that range from light gray to black. They may have  green, blue and/or brown tinges. If the mould is closer to black, it is either the Stachybotrys or Cladosporium molds. If it’s closer to light grey, it is either Aspergillus or Fusarium moulds.

To figure out which type of dark mould and you have, look at the texture. If the basement mould looks slimy, it is probably Strachybotrys. Otherwise, it’s Cladosporium.

To figure out what kind of light coloured mould you have, look at the growth pattern. If the mold grows in disjoint circular patches, it is most likely to be Aspergillus. Otherwise, it’s Fusarium.

The Next Step

If possible, try to get the mould tested in a lab. While the factors described above are usually fairly good indicators, only the professional analysis will be able to tell for sure. If the mold patches are small, you may be able to remove it yourself. However, if the patches are fairly large, you will need professional help.



About moisture and condensation in shipping containers

Nordic Power Desiccant: Piccolo Series

Q: How do Nordic absorbers help to solve moisture problems?

Nordic absorbers contain Calcium chloride that very aggressively grab and absorb moisture from the air. They dry the air. When the air is dry, there are no moisture problems.

Q: Can Nordic absorbers solve all moisture problems?

Well, not all. Some cargoes may be so wet that any reasonable number of Nordic absorbers get overwhelmed. But Nordic absorbers can reliable protect even very difficult cargoes that may contain tons of moisture, such as coffee beans, wood products or paper.

Q: I load my container under dry conditions and it is very tightly sealed. How come I still experience moisture problems?

Your cargo or the packaging, including container floors, pallets and crates, contain moisture that is evaporated into the air during transport. Wet packaging material is the most common cause of unexpected moisture problems.

Q: I have shipped the same cargo for years with Nordic absorbers without any trouble, but now I have a lot of damage. Have you changed the poles?

Check your container and your packaging material. Did you just start to store your pallets outdoors? Does your forklift drive into the container with snow on the wheels? Did you just change supplier of crates? You can’t tell by looking whether wood are carton is dry. The moisture properties of wood and cartons have an exponential character. It makes a huge difference if your pallets moisture content should be 20% instead of 17%, say.

Q: I ship consumer goods in tubes/cans/jars etc that contain no moisture, yet I still have problems.

Consumer goods are often shipped with a lot of cardboard packaging. Even if the boxes seem dry they could literally hold tons of water.

Q: Each container of my cargo of peanuts/coffee/cocoa contains tons of moisture. What difference does it make that Nordic absorbers absorb a few litres during a voyage?

All the important things that happen have an exponential character. That means that a small change in circumstances can have a huge effect on the outcome. Nordic absorbers create circumstances that allow almost all of the moisture to remain in the cargo even while the level of humidity in the air is lowered by a crucial amount, sufficient to prevent damage. It is a question of ”leverage”.

Q: Does it make a lot of difference that my cocoa beans have a moisture content of 8% instead of 7%?

Yes, such a difference could be all the difference between no damage and disaster. The moisture behaviour of most agricultural products have a strong exponential character.

Q: My cargo of peanuts had suffered damage in the centre even though the outside of the cargo looked fine and there was were no signs of condensation?

Lots, if not most, damage to cargoes is caused by prolonged periods of elevated humidity without any condensation (Container rain, Container sweat, Super Saturation Event). It is common that cargoes loaded at cool temperature and then moved into warm condition suffer damage in the centre of the cargo as a result of a difference in temperature between the outside and the centre of the cargo. Warm air from the outside of the cargo becomes humid as it moves into the cooler centre. Nordic absorbers protect against this effect even though the absorbers are mounted on the container walls.

Q: I had damage to my cargo even though I used lots of silica gel and there was no condensation. Would it help to switch to Nordic absorbers?

Calcium chloride absorbs moisture even when the humidity is not very high. This protects the cargo against damage caused by prolonged periods of elevated humidity. Some kinds of steel start to corrode at 70% relative humidity, moulds can grow at 80% relative humidity and at near 90% relative humidity lots of things go wrong. Yet, Nordic absorbers are also at their most efficient protecting against condensation. Most other products, such as silica gels, are really effective only in very humid conditions and in protecting the cargo against condensation damage.

Q: What is so great about Nordic absorbers anyway?

Well, they will not fall off the wall, get punctured during loading and unloading, leave a wet puddle on the cargo or run out after half the voyage. They are installed in seconds without ladders and take up no cargo space. The capacity of each absorber is big, so fewer is required. The cost of an installation is very competitive, even against much inferior alternatives.

Q: How many absorbers do I need?

The number of Nordic absorbers required to protect the cargo depends on the cargo, the temperature conditions during the voyage, the length of the voyage – and just how safe you want to be. For some really dry cargoes e.g.. steel coils or household removals, 2-3 Nordic absorbers are enough. For a lot of ”normal” goods 4-6 Nordic absorbers is about right. Some cargoes with very difficult moisture properties on long voyages may require up to 16 Nordic absorbers.

Q: Do I need to line my container with kraft paper?

Lots of containers are lined with Kraft paper primarily for reasons of hygiene or to simply isolate the cargo from direct contact with the container walls. The liner will act as a kind of sponge, catching and absorbing any droplets of water and then re-evaporating the moisture into the air. If liner is used without Nordic absorbers it could contribute top a kind of pumping effect, drawing moisture out of the cargo. When used together with Nordic absorbers the liner will act as a buffer in extreme conditions, and will prevent any container rain from reaching the cargo. Much the same can be said for so called dew cloths.

Q: My container is absolutely filled with cargo. Will the Nordic absorbers still work?

Moisture diffuses very effectively, even through a seemingly compact cargo. Experience shows that Nordic absorbers will make a difference even to mould growth inside cartons in the cargo. It is, however, necessary that some free space is left in front of each Nordic absorbers. If some Nordic absorbers have collected less water than others inside a container, there may be a problem with air access to those absorbers.

Q: I have problems with mould growth inside my shrink-wrapped pallets. Will Nordic absorbers help?

Yes, so long that there is some access of air through the top and bottom of the pallets. If this is not possible, a spiked roller may be used to tear holes in the shrink wrap.

Q: My shipments of steel/galvanised components/aluminium/machinery etc arrives corroded, stained or discoloured despite heavy packaging. Will Nordic absorbers help?

You can forget about your Tectyl, coatings, oil-paper and plastic wraps that are expensive both to apply and remove. Your container can probably be equipped with a sufficient number of Nordic absorbers to protect against any damage at less cost than your present packaging.

Q: I got some brine on my hands while removing used Nordic absorbers . Is it dangerous?

No it isn’t. Calcium chloride is non-toxic and environmentally safe. It is the second biggest constituent of sea-salt and is liberally sprinkled over icy roads in cold countries. The brine is somewhat similar to very salty seawater, and may cause irritation and rashes if left to dry on the skin. We recommend that you wear gloves and goggles when handling used absorbers, but should you get splashed by brine just wash off immediately with lots of fresh water.

Q: Can I re-cycle my used absorbers?

The absorbers can not be re-used but can be disposed of environmentally friendly. It doesn’t contain any harmful chemicals.
