Powerful technology for workshops, storage spaces and construction sites

High dehumidification performance even at low temperatures

With this compact industrial dehumidifier you can benefit from a budget-friendly dehumidification solution without compromising in terms of workmanship and reliability. The TTK 140 S available exclusively at Trotec is of traditional EU manufacturing and demonstrates in a respectable way that a price level of the Far East is indeed compatible with robust brand quality.

Four swivel castors with RollStop catch and two integrated recessed handles simplify the transport and positioning of the device. Thus you can apply the TTK 140 S flexibly for various drying operations, for example for dry keeping of heated and unheated living, sanitary, storage or basement rooms, garages and workshops.

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 140 S ideally suitable for longer unattended dry keeping tasks, e.g. for construction drying.

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.

Performance and safety are the top priorities here!

The operating switch of the TTK 140 S is protected from dust and spray water by a protective cap, and a slotted hygrostat rotary switch protects against inadvertent misadjustment of the switch position.

The professional hot gas automatic defrost system of the TTK 140 S guarantees effective dehumidification results even at low temperatures, and thanks to the standard external condensate drain this dehumidifier is also suited for longer unattended continuous drying applications, for instance in holiday homes.

The TTK 140 S is optionally also available with an integrated operating hours counter or a MID-compliant dual counter for operating and kilowatt hours.

What does MID compliant mean? 

The European Measuring Instruments Directive (MID) has replaced the existing rules of national approval and subsequent calibration in some areas. As a result, all power meters, which are used for energy consumption billing, must be MID compliant in the future.

TTK 170 S – special equipment features

TTK 140 S – dimensions
In spite of its compact dimensions the TTK 140 S is outstanding with a dehumidification performance of 40 l/24h for rooms sized up to 140 m² or 350 m³. Owing to the rotary piston compressor, its carriage design of robust metal can be transported and stored in any position.
TTK 140 S – operating switch and filling level warning light
A protective cap protects the operating switch and the filling level warning light from dust and spray water. The slotted hygrostat rotary switch offers protection against unintended changes to the setting of the switch position.
TTK 140 S – recessed handles
The integrated recessed handles make the transport and positioning of the TTK 140 S to every desired location even easier.
TTK 140 S – external drain integrated as a standard
The external condensate drain that comes as a standard makes the TTK 140 S ideal for longer and unattended continuous drying applications.
TTK 140 S – automatic mode
The TTK 140 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 32 % and 100 %, depending on the air humidity value in the room which is to be reached.
TTK 140 S – automatic defrosting
The TTK 140 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 140 S carries out fully automatic self-defrosting, if required.
TTK 140 S – memory function
The TTK 140 S is provided with a memory function. In the 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 140 S – permanent mode
In the permanent mode, the TTK 140 S dehumidifies the room air in continuous operation. Therefore it is ideally suited for longer unattended dry keeping tasks and professional construction drying applications. The condensate produced in the course of the dehumidification process should be discharged via the connectable drain hose, so that you do not have to keep emptying the water tank.

Application examples from practical experience:

TTK 140 S – storage hall
The commercial dehumidifier TTK 140 S, by its hygrostat-controlled automatic operation, provides for an optimum room climate, e.g. in storage halls. The target value can be adjusted via a rotary switch from a minimum value to the maximum value.
Shells can be dried perfectly and easily in no time with the powerful and comfortable commercial dehumidifier TTK 140 S. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.
The TTK 140 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.

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.
