The classical all-rounder!

Whether you want to dehumidify and dry constructions sites, living spaces, bedrooms, shower and basement rooms, laundry rooms, weekend cottages, caravans, boats, or to continuously keep storage facilities, archives, laboratories, garages, bathrooms, washrooms and changing rooms dry – the powerful dehumidifier TTK 171 ECO is an especially economical solution for many typical commercial dehumidification tasks.

The carriage construction with handle bar, recessed handles and big wheels makes transporting even on difficult terrain or stairways much easier.

For quick start-up the dehumidifier TTK 171 ECO comes with an easy-care control panel with digital display of all functions. For hygrostat-controlled automatic operation the target value can be selected in percentage steps, this value will then be indicated along with the current actual value.

By means of the timer switch-on and switch-off time can be configured and owing to the integrated memory function the settings are saved even after a power interruption.

Permanent mode for construction drying applications

The possibility of connecting an external condensate drain – if required with an optional condensate pump – also makes the TTK 171 ECO ideally suitable for longer unattended dry keeping tasks, e.g. for construction drying.

With an optional air hose connection for drying hollows

In suspended ceilings, in bathtub hollows, in cassette walls or cable ducts – if moisture has entered hollows that are difficult to access, you should act quickly in order to prevent the formation of mould.

As the TTK 171 ECO is equipped with a special pressure fan, the device can also be used for the selective admission of dry air or for drying hollows. To do so, simply attach an air hose to the optionally available adapter connecting piece.

Radial fan with 3.2 MPa air pressure

The air hose can be installed in the hollow via inspection flaps or manually added apertures. With an air pressure of 3.2 MPa on the outlet side, the radial fan mounted in the TTK 171 ECO offers an especially extensive throwing range. The dry air is induced into the hollow via the air hose connected on the air outlet by means of an adapter. The air that has been blown in then escapes again through an aperture that is already available or that has been added manually in the hollow casing, in this way allowing for the moisture to be dried out by and by.

Note: If heavy dirt, dust or even mould has settled in the hollow, the space should not be inhabited or used at the time the drying process is carried out, if possible, since otherwise the dust particles and mould spores may spread everywhere. In this case we recommend additionally using an air cleaner.

Investment protection for your drying devices

Particularly during construction drying operations in summer or when drying water damages, it is very likely that climate conditions arise which may significantly shorten the lifetime of condenser dryers – regardless of the make. We as manufacturer care about the fact that for process-related reasons your condenser dryers often have to be replaced much too soon, hence we have prepared a valuable practical recommendation relating to the investment protection of your drying devices.

Technical construction drying

Did you know that every construction dryer is at the same time a commercial dehumidifier, but that not every commercial dehumidifier is automatically a real construction dryer? Here you can find out the reasons for this, and why hot gas defrosting makes the decisive difference ...

In spite of its compact dimensions the TTK 171 ECO is outstanding with a dehumidification performance of 52 l/24h for rooms sized up to 90 m² or 230 m³. Owing to the rotary piston compressor, its carriage design of robust steel can be transported and stored in any position.
TTK 171 ECO – dimensions
The control panel of the TTK 171 ECO is provided with a clear design and is easy to understand. The digital display for example shows you the current relative humidity level in the room.
TTK 171 ECO – control panel
Thanks to the special pressure fan, the TTK 171 ECO can be be used for the selective admission of dry air or for drying hollows. To do so, simply attach an air hose to the optionally available adapter connecting piece.
TTK 171 ECO – air hose connection
The removable water tank has a storage capacity of 5.5 litres. The device stops automatically when the tank is full and indicates this via LED. The removable air filter protects the device interior against soiling and can be easily wiped or washed out.
TTK 171 ECO – water tank and air filter
The TTK 171 ECO ensures automatically that the target value entry is kept constant. When this value is exceeded, the device switches off automatically and also switches on again automatically when the value falls below the target entry. The target value preselection is between 20 % and 90 %, depending on the air humidity value in the room which is to be reached.
TTK 171 ECO – automatic operation
Use the practical timer function to switch the device on or off after a defined number of hours. The time can be programmed in increments of 1 hour (1 to 24 h). The use of the timer prevents unnecessary operating periods and allows you to individually adapt the dehumidification to your needs.
TTK 171 ECO – timer function
The TTK 171 ECO is provided with a memory function. In case of an unexpected switch-off due to a power interruption, this function makes the device restart with the previously selected setting as soon as the power supply has been restored.
TTK 171 ECO – memory function
In the permanent mode, the TTK 171 ECO dehumidifies the room air in continuous operation. Ideal for longer unattended dry keeping tasks and professional construction drying applications. To avoid that you constantly have to drain the water tank, a condensate drain hose can be connected.
TTK 171 ECO – permanent mode
The commercial dehumidifier TTK 171 ECO, by its hygrostat-controlled automatic operation, provides for an optimum room climate, e.g. in storage halls. The target humidity value can be preselected in percentage steps and will then be indicated along with the current actual value.

Shells can be dried perfectly and easily in no time with the powerful and comfortable commercial dehumidifier TTK 171 ECO. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.
TTK 171 ECO – shell
The TTK 171 ECO is also an excellent choice when it comes to its use for water damage restoration. The process of drying the spaces can be substantially accelerated in such cases of damage, as a consequence considerably reducing mould formation. A connectable air hose also makes it possible to dry hollows.

Proper energy billing for existing equipment without meters?

You're using this or another electrical appliance without MID-compliant energy consumption meter of which you have to report the current consumption to insurance companies? Then the BX50 MID is the perfect solution. Just install it between the device and a fixed socket – done!

Fan assistance for construction drying

Fan assistance

Quicker construction drying by air circulation

The drying time can be reduced by half if construction dryers and fans are combined. In doing this, each dryer is supplemented with a fan, which significantly improves the drying performance and thus also the duration of the drying process.

The increased air circulation results in a quicker evaporation of the humidity, for the higher the flow rate at the material surface, the sooner will the drying process be completed.
The axialfans of the TTV series and TTV-S series are especially suitable to provide assistance with regard to the drying process.

External condensate pump

Accessory tip:

External condensate pump for continuous operation

This optionally available condensate pump is compatible with all TTK-ECO models from Trotec and is ideally suited for longer, unattended dry keeping applications. With a pump height of up to 5 metres the condensate can be pumped from the collection container of the construction dryer into a larger container or outside. This makes it possible to let the construction dryer run in continuous operation without a full collection container interrupting the dehumidification process.
