TTK 170 S – overview

The universal all-rounder!

Whether for drying after water damage, construction drying or dry keeping of heated or unheated storage and work rooms, with this universal dehumidifier you can benefit from a budget-friendly dehumidification solution without compromising in terms of workmanship or reliability.

For behind the price tag on a Far East level, there is a robust metal plate from traditional EU manufacturing accommodating tried and tested brand technology that runs and runs and runs. Easy-care, low-maintenance, reasonably priced.

The TTK 170 S is equipped with a professional hot gas automatic defrost system and dehumidifies rooms with a size of up to 180 m² and a performance of up to 50 litres in 24 hours. This high-performance construction dryer is hygrostat-controlled. The desired humidity level can be preselected between 32 % and 100 % RH using the practical rotary switch. Furthermore it generates an air volume of 580 cubic metres per hour. Thanks to its stable carriage construction and the large impellers you can easily and frequently change its application site.

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

Safe and powerful!

The operating switch and the filling level warning light are 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 condensation tank indicator light lights up when the condensation tank is full. In addition, the TTK 170 S switches off automatically when the water tank is full.

Inside, a professional hot gas automatic defrost system guarantees effective dehumidification result even at low temperatures, and thanks to the external condensate drain integrated as standard the TTK 170 S is also suited for longer unattended continuous drying applications and for construction drying.

The TTK 170 S is exclusively available only at Trotec and can be optionally delivered with an integrated operating hours counter or MID-compliant dual counter for operation hours and kilowatt hours.

What does MID-compliant mean?

In some areas, the Measuring Instruments Directive (MID) replaces the previous regulation of national authorization and subsequent calibration. As a result, all energy meters in Europe used for energy consumption-based billing have to be MID-compliant from now on.

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.

TTK 170 S – special equipment features

In spite of its compact dimensions the TTK 170 S is outstanding with a dehumidification performance of 50 l/24h for rooms sized up to 180 m² or 450 m³. Owing to the rotary piston compressor, its carriage design of robust metal can be transported and stored in any position.
TTK 170 S – dimensions
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.

The integrated recessed handles make the transport and positioning of the TTK 170 S to every desired location even easier.
TTK 170 S – recessed handles
The external condensate drain that comes as a standard makes the TTK 170 S ideal for longer and unattended continuous drying applications.
TTK 170 S – external drain integrated as a standard
The TTK 170 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 170 S – automatic mode
The TTK 170 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 170 S carries out fully automatic self-defrosting, if required.
TTK 170 S – automatic defrosting
The TTK 170 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 170 S – memory function
In the permanent mode, the TTK 170 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.
TTK 170 S – permanent mode
The commercial dehumidifier TTK 170 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.
TTK 170 S – storage hall
Shells can be dried perfectly and easily in no time with the powerful and comfortable commercial dehumidifier TTK 170 S. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.
TTK 170 S – construction shell
The TTK 170 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.

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.
