Damp walls? Mould? Rust? Whatever your problem, we have the solution!

Many of the problems which we are confronted with in the course of our daily lives are caused by high humidity levels in the home, the office or in the workplace. Yet whether it’s that musty, acrid smell, those ominously dark stains spreading out over a wet wall or even worse festering mould or rampant rust, the solution is often the same: a dehumidifier. But which dehumidifier is best to suit my needs? Dehumidifiers are designed to draw off exactly the amount of excess moisture in the air that can turn a comfortable, agreeable and healthy indoor climate into an uncomfortable, disagreeable and unhealthy one. A dehumidifier doesn’t just monitor the ambient air and check humidity levels, it ensures that the humidity level you have selected is maintained for as long as you want. But which dehumidifier is the right one for you? Dehumidifiers come in all shapes and sizes. They can be packed with an array of different functions and valuable features. But the one thing that you should be looking out for most when you choose the model that you need to solve your problem is a dehumidifier that you know you can rely on.

Which is why we would like to show you everything you need to know about the dehumidifiers from Trotec…

Why do I need a dehumidifier?

There are a number of reasons why the right indoor climate is of such particular importance. The right indoor climate does not only enhance the way you feel, it also plays a significant part in protecting your health as well as your prized possessions and property. That’s because a relative humidity of only 70% is all that mould spores need to multiply and spread while a mere 60% is enough to cause corrosion and rust.

Mould, stains and rust. What you can do to prevent damage caused by moisture!

The first thing that you need to be doing is keeping an eye on the humidity level in your home and in your workplace. Dehumidifiers are especially important in rooms where there are high levels of moisture like kitchens, bathrooms or utility rooms, for example.

Damage caused by moisture is not only unsightly, or quite simply plain ugly, it can quickly become an exceedingly expensive problem. Especially when whole rooms or even houses are affected. This would seem to be reason enough to invest in a reliable and effective dehumidifier that can prevent such damage from occurring.

Protect your home, your family and your health!

What are the most typical areas of application for a dehumidifier?

Dehumidifiers are designed to combat high levels of moisture and regulate the indoor climate in a variety of different scenarios. They are excellently-suited for use in the home and in the office, but they are just as well-suited for use on boats or in museums, in work or repair shops, in various fields of industry or in holiday homes:

  • Dehumidifiers for different scenarios

    Did you know that an adult can give off as much as 0.5l of water through respiration and transpiration in a single night? The moisture that evolves from the fact that you breathe and sweat while you sleep can negatively affect the moisture content of the room you are in. But you are not the only one who is contributing to the level of moisture in the ambient air. Your plants and pets also give off moisture. And so do you or other members of your household when you do certain chores or activities like washing or cooking or have a shower or bath. All these factors that contribute to higher humidity levels cannot be compensated by airing alone.

    The Comfort Dehumidifiers in the TTK S Series have been designed and developed to meet your individual requirements and to blend into their surroundings as aesthetically as possible. No matter which dehumidifier you choose: they all have different dehumidification capacities for different scenarios and different room sizes.

     
  • In the workplace or office

    Another place where you should not underestimate the positive or negative impact which the indoor climate can have on you and your work is your workplace or office. Did you know, for example, that the productivity of a workforce can depend on the right relative humidity and the right room climate? People in general have less drive and suffer from both mental and physical fatigue when the relative humidity is too high and feel uncomfortable and find it stifling when the temperature levels are above normal.

    The dehumidifiers in the TTK S Series are just right for such scenarios. The dehumidifiers significantly and perceptibly change the room climate to the better – and provide you with a healthier and cleaner environment.

     
  • Museums, archives, libraries

    Special objects deserve special care and attention. And because works of art, valuable collections and important documents are often irreplaceable, it makes sense both from an economical and from a sentimental point of view to protect the valuable assets that are stored in museums, archives or libraries against damage caused by moistures.

    High humidity levels can cause irreparable damage to valuable objects. Books can become sodden and the pages wavy, paintings can turn yellow and become covered with stains and documents and files can become damp and mildewy. Such damage is often irreversible, and if the objects in question can be restored, then only at huge cost to the owner. That’s why we think that a dehumidifier is so important. One small investment that can control the relative humidity and save you a potentially huge sum – and the worry and stress that inevitably goes hand in hand with such damage.

     
  • Industry

    The indoor climate often plays a key role in industry. This may be either for economical reasons or for reasons of hygiene. But whatever the reason, high humidity levels, which often occur during industrial production processes, during distribution and during storage are often not just an unwelcome phenomenon, they are an essential part of the equation and have to be factored in.

    That’s why we have developed professional dehumidification systems which have been designed especially for use in industry and which work according either to the adsorption or to the condensation principle, depending on the area of application for which they are needed. These systems enable you to control the indoor climate and reliably regulate the relative humidity in your production sites, plants or facilities in order to prevent condensation, corrosion and mould from forming and to protect your goods, your workforce
    and your interests.

How does a dehumidifier work?

There are two types of dehumidifiers: Adsorption dryers and Condensation dryers. We would like to show you the difference between the two types of dehumidifiers and which of the two technologies is more suitable for your individual requirement…
 
 

Dehumidifiers which work according to the condensation principle

Dehumidfiers which work according to the condensation principle

This type of dehumidifier works very much like a conventional air conditioner with a compressor which conducts a refrigerant past a cooling block. The moist air which is in the room that the dehumidifier has been installed in is also conducted past the cooling block, this time by using a fan, where it then condenses because it falls below the dew point temperature and is collected in the dehumidifier’s tank.

For which applications is a dehumidifier which works according to the condensation principle most well-suited?

One of the biggest benefits which such a dehumidifier has to offer is the fact that it is economical to run. Compared to a dryer that operates according to the adsorption principle, a condensation dryer consumes only 30-40% of the energy at an ambient temperature of 12°C to dehumidify the location at which it has been installed. The energy consumption starts to increase the lower the temperature gets so that an adsorption dryer becomes the more viable and efficient alternative as soon as the temperature falls below circa 7°C.

In addition, condensation dryers are, as a rule, lower in price.

It is important to remember that a condensate dryer can only achieve a relative humidity of about 35%. This means that if you plan to work with humidity levels that are lower, then you will need an adsorption dryer to control your indoor climate.

Dehumidfiers which work according to the adsoption principle

Dehumidfiers which work according to the adsoption principle

Unlike condensation dryers, adsorption dryers operate without a refrigerant. Dehumidifiers which work according to the adsorption principle use a silicagel which soaks up the excess moisture which is present in the ambient air. In the second stage of the regeneration process, air that has been previously warmed up absorbs the moisture that has collected in the sorption material and transports it away from the dehumidifier.

Which applications is a dehumidifier which works according to the adsorption principle best-suited for?

Dehumidifiers which work according to the adsorption principle are an extremely effective solution for combating high humidity levels at low temperatures. Whereas due to the nature of their design condensation dryers are prone to suffer from icing at low temperatures, which inevitably means that they then become less efficient, adsorption dryers are ideal for use in environments where the temperatures are extremely low. The dehumidifiers in the TTR Series are built to operate in temperatures as low as -20°C and as high as 35°C.

In addition, adsorption dryers can achieve relative humidity levels below 35%. This special feature makes them ideal for use in a variety of sectors in industry.

Which dehumidifier is the right one for me?

There are several things which you have to watch out for when you have made up your mind and decided to buy a dehumidifier.
We have compiled a list of questions which you need to ask yourself before you go on to the next step and purchase your dehumidifier. After all, we would not want you to regret your decision to buy one of our dehumidifiers in any way:
Decision support dehumidifier

 
 

  1. How high is the dehumidification performance?

    The chances are this is the one question you will want to have answered first. How many litres of moisture can the dehumidifier draw out of the ambient air in a single day? But there are a number of other factors which have to be taken into consideration before you can decide which dehumidifier meets your specific requirements. Factors like the size of the room that needs to be dehumidified and the surrounding temperature. We have developed an easy-to-use online calculator which will help you to determine which dehumidifier is the right dehumidifier for you.

  2. What is the room temperature going to be like?

    We can recommend two types of dehumidifiers depending on whether the rooms you wish to install your dehumidifier in are heated or not. Condensation dryers are by far the more economical alternative when it comes to dehumidifying heated rooms whereas adsorption dryers are far more reliable and also more efficient when the rooms or facilities are unheated and temperatures are very low.

  3. What do you need your dehumidifier for?

    Generally speaking, it would be fair to say that in the field of dehumidification we differentiate between dehumidifiers which are designed to keep rooms dry and ensure that the relative humidity is kept at a constant level and dehumidifiers which are used in the scope of water damage remediation and which are installed because they are capable of extracting vast amounts of moisture out of the ambient air extremely quickly and effectively.

    The dehumidifier you wish to buy must have a much higher dehumidification performance if you are planning on using it to help dry out a building than if you are planning on using it to keep the rooms in your home your workplace or a storeroom dry. As a guideline you can say that a TTK 200, for example, is ideally-suited for drying out a room with a volume of up to 200 m³ whereas the same dehumidifier is easily able to keep the relative humidity in a room double the size at a constant level.

     
     
     
     

  4. Which extras do I need?

    Dehumidifiers are equipped with a wide range of practical functions and features which can increase their efficiency and also make them more comfortable to use. That’s why you need to know which features you think you can happily do without and which features you really need to optimise your dehumidifier’s performance. Here is a compilation of some of the features which you really shouldn’t be compromising on:

    Dehumidifiers with extra features

    • Humidistat:

      A humidistat enables your dehumidifier to regulate the relative humidity automatically. This is definitely a must-have unless you think that there’s nothing wrong with keeping a constant eye on your dehumidifier.

    • Automatic de-icing:

      This may seem to be little more than a nice little extra, but it can make all the difference when you are using a dehumidifier that works according to the condensation principle. Such dehumidifiers are, by the nature of their design, prone to icing at low temperatures. The automatic hot-gas de-icing function can counteract such icing by freeing the evaporator of ice when the dehumidifier’s performance starts to lag, thus ensuring that your dehumidifier works more efficiently more of the time.

    • Overflow protection:

      This smart little feature automatically stops the tank of your dehumidifier from overflowing when it is full. This means that the water which your dehumidifier has drawn out of the air remains in your unit and not over the floor.

    • Twin condensate discharge system:

      You have the choice. You may either choose to empty the waste water tank of your dehumidifier the normal way or you may wish to connect a hose to the outlet at the bottom of the unit and run the water off to a nearby sump or drain. This added feature means that your dehumidifier is even more flexible and also excellently equipped for non-stop use over longer periods.

    • Dual counter:

      The dual counter allows you to document the number of hours that your dehumidifier is in operation and enables you to keep a close watch on the energy consumption and costs.

    • Air filter:

      An air filter may be a standard feature in many dehumidifiers, but you need to make sure that it is also easily accessible and easy to clean. If you can’t reach the air filter and you can’t clean it, then it cannot perform the task it was designed to do. The quality of the air in the room will then suffer accordingly.

The ideal room climate

A dehumidifier is not just another needless accessory. It is a state-of-the-art appliance that provides you with a comfortable and healthy indoor climate. But which humidity values are ideal and which are not?

The ideal indoor climate, the climate that you feel most comfortable in, is a combination of the right temperature and the right relative humidity. When the relative humidity is too high, then high temperatures are also perceived differently: the heat becomes uncomfortable, even stifling. When the relative humidity is too low, then the room temperature is perceived to be lower than it actually is. For most people the ideal room temperature is somewhere between 18 and 24°C and the ideal relative humidity is between 40 and 70 %.

Dehumidifiers for extreme situations: in building drying and water damage restoration

Dehumidifiers are normally used to keep rooms in homes, offices and workplaces dry. But after flooding or high water when vast amounts of moisture have to be removed or in new builds when the building materials are still fresh a dehumidifier can end up being pushed to its limits. That’s why we at Trotec have developed a series of building dryers that are more than a match for any amount of moisture and which you can totally rely on.

The difference between building dryers and regular dehumidifiers

The most important outstanding difference between the building dryers in the TTK Professional Series and a regular dehumidifier is, of course, the performance. The most powerful of our dehumidifiers can extract a stunning 400 litres out of the ambient air in only a single day. In addition, our building dryers are far more robust than the dehumidifiers you would normally use in your home. They have to be. Otherwise they would not be able to stand up to the harsh demands which are put on them when they are used on changing building sites to dry out new buildings or when they are deployed to dry buildings and prevent further, even more potentially harmful, damage from occurring in the aftermath of flooding or high water.

That’s also why the building dryers in the TTK Professional Series have to be mobile and easy to transport and why they are equipped with extremely sturdy, heavy-duty, rubber-tyred wheels as well as an extremely practical bar handle. Even the largest of our building dryers, the TTK 1500, is constructed as a mobile unit and is therefore equally excellently-suited for use on building sites and in changing scenarios.

Because building dryers are able to extract far greater quantities of moisture out of the ambient air than the dehumidifiers in the TTK S Series, they do not have an integrated waste water tank. The water is not collected in the unit’s housing, it is conducted away from the unit via a hose that is connected to the drain outlets. The reason for this major difference in design is the difference in the demands that are placed on a dryer of this class and category. Whereas our range of elegantly-crafted conventional dehumidifiers has been designed to blend into their surroundings and be especially comfortable to use, our building dryers are built to be extremely robust, exceptionally mobile and exceedingly efficient when it comes to dealing with sheer unbelievable amounts of moisture.

But there is one thing which the dehumidifiers in the TTK S Series and the building dryers in the TTK Professional Series have in common – they are all high-quality products that have been built to last.
