Commercial dehumidifier TTK 170 ECO

Highly efficient. Extremely robust. Incredibly low-priced.

The TTK 170 ECO is our pragmatic solution when an equally low-cost and high-quality construction dryer is required

In case of the TTK 170 ECO the name says it all: Its favourable price impresses as much as the high dehumidification performance, and this attractive value-for-money ratio makes the TTK 170 ECO the first choice for all commercial users looking for a particularly robust and economic dehumidifier.

Thanks to the professional hot gas automatic, the TTK 170 ECO achieves high dehumidification levels also at low temperatures in unheated rooms or on cold building sites.

A frequent change of location from one building site to another or the application in rough surroundings and on difficult terrain does not pose a problem for this condenser dryer:

The robust steel construction in carriage design with transport handle and big wheels can withstand a fair bit and can easily be transported to any operating site.

Additional transport safety is provided by the practical cable holder at the back of the device – and seeing as the TTK 170 ECO comes equipped with an efficient rotary piston compressor, the low-maintenance device can be transported and stored in any position.

Owing to an external condensate drain and optionally available condensate pump, the TTK 170 ECO is further ideally suited for longer unattended dry keeping applications, the duration of which can be determined precisely by means of the integrated operating hours counter – perfect for commercial applications. Moreover, this dehumidifier comes with an additional connection for an optional hygrostat for the humidity-dependent drying control.

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.

In spite of its compact dimensions the TTK 170 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.

The removable water tank has a storage capacity of 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.

In the permanent mode, the TTK 170 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.

The commercial dehumidifier TTK 170 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 170 ECO. This prevents major delays caused by necessary drying processes in the construction project, even at low temperatures.

The TTK 170 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.

A few practical benefits:

  • Particularly economical solution for typical dehumidification applications in the commercial sector
  • High dehumidification performance even at low temperatures
  • Robust steel construction in carriage design
  • Portable and easily stored anywhere thanks to its rotary compressor
  • Hot gas automatic defrosting
  • External hygrostat connection

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.
