TTK 125 S commercial dehumidifier

“Nobody can offer as many litres at this weight”

Good things come in small packages: Power pack TTK 125 S

The TTK 125 S combines advanced detail solutions for powerful drying applications with a weight-optimized construction in a tried and tested German industrial design – protected prototype.

The inner values are in no way inferior to the impressive enclosure: All electric components are specially enclosed to protect the electronic equipment from anything dangerous which may enter and impair the functionality and durability. Thus, the TTK 125 S is also perfectly suitable for drying in rough conditions.

Due to its extremely low-maintenance design, the TTK 125 S is easy to clean and thanks to its low power to weight ratio and its clever mobility features, it is easy to transport. Nevertheless, in terms of dehumidification capacity, it is no lightweight:

Compared to cheaper reciprocating compressors, the high-quality 0.58 kW rotary compressor of the TTK 125 S offers the advantage of higher performance with comparatively lower power consumption – and creates additional reserves for high dehumidification performance even in unheated rooms.

As well as this, compared with other defrost systems, the high-quality hot gas automatic defrost of the TTK 125 S guarantees a much more efficient dehumidification performance without pausing on a time interval during which no dehumidification occurs!

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 ...

Environmentally friendly refrigerant R290

Propane (R290) as environmentally friendly refrigerant in dehumidifiers

Every year, several million tonnes of environmentally harmful CO2emissions (greenhouse gases) are emitted into the air by synthetic refrigerants. For this reason, the utilization of alternative refrigerants has become one of our key objectives. By using propane (R290) as refrigerant, this dehumidifier makes a valuable contribution to protecting our climate.

The natural refrigerant propane (R290) is an organic compound belonging to the group of hydrocarbons. Unlike synthetic refrigerants the environmentally friendly propane (R290) comes with neither ozone depletion potential (ODP = 0) nor a noteworthy greenhouse effect (GWP = 3).

Additional bonus for the environment: Owing to its excellent thermodynamic properties, propane (R290) is a particularly energy-efficient refrigerant thereby additionally reducing your energy costs.

The top drying performer of its power to weight class

This innovative condenser dryer can dehumidify impressive 32 litres within 24 hours. Astounding for a robust and compact package which only weighs 26 kilograms.

In practice, the TTK 125 S seems much lighter than that, because its robust Trotec ergonomic recessed handles with an inner Grip-Clip provide an optimal hold while carrying. With its four sturdy swivel casters with wheel locks, tight construction sites are no problem.

Even in storage, the TTK 125 S makes a good impression – because it only needs surprisingly little space. Due to its two practical stacking grooves on top, equally sized TTK-S devices can be safely stacked to save space during transport and storage.

As with all commercial dehumidifiers of the TTK-S series, the TTK 125 S has a built in operating hours counter which records the precise duration of work accurately and reliably. A dual counter for additional detection of power consumption is optionally available.

TTK 125 S – special equipment features

TTK 125 S - control panel
Clearly arranged control panel – protected by protective bars.
TTK 125 S - operating hours counter
The standard operating hours counter of the TTK 125 S commercial dehumidifier is optionally available as a dual counter for operating and kilowatt hours.
TTK 125 S - stacking grooves
A special enclosure reliably protects the TTK 125 S dehumidifier electronics from dangerous inclusions.
TTK 125 S - electronics protection
Two stacking grooves make it possible to stably stack equally sized TTK-S commercial dehumidifiers to save space.
TTK 125 S - automatic mode
The TTK 125 S 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 50 % and 90 %, depending on the air humidity value in the room which is to be reached.
TTK 125 S - automatic defrosting
The TTK 125 S comes with function for automatic defrosting. When the room temperature is below 11 °C, the evaporator would freeze during dehumidification. This is why the TTK 125 S carries out fully automatic self-defrosting, if required.
TTK 125 S - memory function
The TTK 125 S has a memory function. Thanks to this, the device restarts after an unexpected shutdown due to a power interruption with the preselected setting as soon as the power supply is available again.
TTK 125 S - permanent mode
In order to continuously drain the condensation water, a pipe can be connected on the rear of the device. This is especially suitable for cellar or storage spaces which are subjected to mould formation by excess humidity.

TTK 125 S - warehouse
The commercial dehumidifier TTK 125 S, 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.
TTK 125 S - shell
Shells can be dried perfectly and easily in no time with the powerful and comfortable commercial dehumidifier TTK 125 S. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.
TTK 125 S - water damage restoration
The TTK 125 S 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.

With a pump performance up to a distance of 50 m and a maximum delivery head of 4.3 metres, this pump is ideally suitable for longer unattended dry keeping applications in continuous operation – just add it to your order right away!

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 axial fans of the TTV series and TTV-S series are especially suitable to provide assistance with regard to the drying process.

Protective hood

A practical protective cover is optionally available for all commercial dehumidifiers of the TTK-S series.

So that weather conditions, dust etc. can no longer clog the TTK 125 S dehumidifier.
