Construction dryer at its best!

Designed as reference class of professional construction dryers the TTK 900 MP practically leaves nothing to be desired. Its tough design and robust components ensure a permanently maximum dehumidification performance and value retention. Owing to a perfect combination of an especially powerful and efficient rotation compressor, an utterly robust high-pressure radial fan as well as high-quality electronic and mechanical components, the TTK 900 MP can impress with an excellent dehumidification capacity, especially at low ambient temperatures.

Powerful air-circulating radial fan with dry air outlet on both sides

In order to quickly distribute the dry, dehumidified air in the entire room, the TTK 900 MP is fitted with a dry air outlet on both sides. This way, the dry air is blown out at a high volume by the high-pressure radial fan via two air outlet sides without dynamic pressure and can flow evenly through the room – an enormous practical advantage for the fast drying of large rooms!

At the same time, the TTK 900 MP has been consistently designed to provide maximum mobility for ever-changing sites of operation and to withstand rough working conditions. This is why the TTK 900 features not only a carriage with adjustable push handle, but also large wheels with non-marking rubber tyres – all combined in a robust metal housing.

Along with its minimized energy and floor space requirements the TTK 900 MP presents the ultimate construction dryer, which is also suitable for water damage drying and dewatering waterworks facilities or large storage facilities with low ambient temperatures.

Effective process for high dehumidification performance of up to max. 110 l/24 h

For an effective dehumidification, the TTK 900 MP comes equipped with a powerful automatic two-point hot gas defrost system based on the bypass procedure. This system only requires very short defrost phases, which increases the performance level and makes the device ideally suited for an effective dehumidification in low-temperature surroundings such as unheated rooms.

If required, a hygrostat can be connected to the TTK 900 MP enabling automatic humidity-controlled dry keeping in continuous operation. A condensate pump for condensate discharge across storeys is also available for this purpose.

TTK 900 MP with VarioDry technology – unique in the world!

The unique combination of an innovative heat exchanger design with optimised evaporator circuit and highly efficient EC radial fan makes it possible: The TTK 900 MP can be easily adjusted to the desired operating environment and obtains the optimum setup for the respective type of application by means of just one switch setting. Both high relative humidity levels and lower temperatures (e.g. when drying new buildings) or lower relative humidity levels in warmer environments for water damage restorations are pefectly suitable for the device. Simply select the construction drying or water damage restoration mode via the VarioDry function switch, and the TTK 900 MP automatically adjusts its device setup to the maximum drying performance in this operating mode!

At the same time, the new, elaborate two-point automatic hot-gas defrosting system ensures extremely short defrosting times and thus considerably longer drying cycles.

Benefit now from 20 % more efficiency than before

The TTK 900 MP impresses with 10 % more performance at 10 % less energy consumption compared to the predecessor model TTK 800. Thus, it can boast the best energy coefficient in its class as a result of an elaborately balanced energy management system! In plain words: No other dryer in this area achieves a higher kW output in litres than the TTK 900 MP – across all fields of application, water damage restoration and drying new buildings.

The sum of these advantages makes the TTK 900 the new reference for professional dryers worldwide!

100 % construction dryer – the name says it all

It's not just a name that turns a commercial dehumidifier into a true construction dryer. The name is an obligation: the device must be able to dry large amounts of air in continuous operation, on the construction site, in cool environments. After all, construction dryers make their living in drying applications, not in the warehouse and particularly not in the workshop.

Which is why the construction dryers of the TTK series have been consistently designed for high dehumidification performance and a long lifetime. Even in continuous use on the construction site, the devices work reliably and without interruption – and if maintenance is required, it can be carried out more quickly than ever before:

Innovative central chassis – low-maintenance modular design

TTK 500 and TTK 900 MP have an innovative central chassis from which the robust metal housing can be quickly and easily removed. Ideal for service, maintenance and cleaning tasks.

And the entire electronic equipment is not only specially enclosed and thus reliably protected against harmful deposits – it is also designed in a modular fashion and all individual electronics modules are provided with maintenance-friendly plug connections. The replacement of individual modules is therefore quick and easy, even on site: unplug, replace module, plug back in – done. Maintenance-related periods of non-use can thus be reduced to a minimum.

Refrigerant R-454C – less GWP, more efficiency and safety

Refrigerants frequently used in compression refrigeration dryers up to now have a high greenhouse potential. One of the reasons for the EU's F-gas phase down – and for Trotec a self-evident obligation to use not only environmentally friendly but also an equally safe and efficient refrigerant for the TTK construction dryers of the latest generation.

R-454C scores in all three aspects – eco-friendliness, safety and efficiency. Therefore, R-454C is the refrigerant of our choice for the powerful TTK construction dryers.

Unlike natural refrigerants such as propane, R-454C is only flammable with high ignition energy. Consequently, there is no risk of explosion even in the event of a leak, which means that operation and maintenance of the heat exchanger remains simple and safe. The non-toxic R-454C is ideally suited for hermetically sealed refrigeration systems and is not only characterized by a high COP (coefficient of performance), but also by a very low GWP (global warming potential) of less than 150 and an ODP (ozone depletion potential) of 0. This means that R-454C contributes at least 10 times less to the greenhouse effect when it escapes into the atmosphere than commonly used refrigerants.

A short snap shot of the classes of water damage 

Class 1 (least amount of water, absorption and evaporation): Water losses that affect only part of a room or area, or larger areas containing materials that have absorbed minimal moisture. Little or no wet carpet and/or cushion is present

Class 2 (large amount of water, absorption and evaporation): Water losses that affect at least an entire room of carpet and cushion (pad). Water has wicked up walls less than 60cm. There is moisture remaining in structural materials; e.g., plywood, particle board, structural wood, VCT, concrete and substructure soil

Class 3 (greatest amount of water, absorption and evaporation): Water may have come from overhead. Ceilings, walls, insulation, carpet, cushion and subfloor in virtually the entire area are saturated

Class 4 (specialty drying situations): These consist of wet materials with very low permeance/porosity (e.g., hardwood, plaster, brick, concrete, light weight concrete and stone). Typically, there are deep pockets of saturation, which require very low specific humidity. These types of losses may require longer drying times and special methods

Air Exchange is example if the room is 100 cubic meters LxWxH and the dehumidifier is 400 cubic meters per hour that means that 4 times an hour the complete air from the room with air movement assistance will exchange the air through the dehumidifier.
