Stationary industrial desiccant dehumidifiers of the TTR series

Durable, low-maintenance, extremely flexible and modularly configurable with high dehumidification performance even at low dew points

The TTR series combines premium quality and maximum economic efficiency

Humidity control at its best

With our robust high-performance dehumidifiers you constantly benefit from a perfect solution with regard to drying applications. The TTR units ensure efficient and permanent dehumidification with a high capacity, even at low dew points.

The application possibilities for these industrial desiccant dehumidifiers are as versatile as their comprehensive standard equipment and the numerous additional equipment options facilitate a virtually custom-tailored adaptation of these devices to meet any requirement.

High Performance made in Germany

All industrial dehumidifiers of the TTR series are developed and manufactured in Germany according to the highest quality standards. They exclusively consist of efficient branded components of the latest generation of technology supplied by leading component manufacturers.

The TTR platform strategy consisting of four construction modules with altogether eleven devices of different performance classes ensures a maximum of quality and cost-effectiveness.

Thanks to the internal heat recycling process as well as the high level of resilience and performance of their special sorption rotors, the desiccant dehumidifiers of the TTR series are among the most economical dehumidifiers of their kind!

High dry air flow rate even with a low dew point

For the purpose of dehumidification the desiccant dehumidifiers of the TTR series take advantage of the vapour pressure gradient between the humid air and a hygroscopic sorption agent incorporated in a desiccant wheel with an extremely large surface structure. This procedure ensures a high dehumidification performance even at a low humidity level and low air temperatures.

TTR Trisorp Dual principle

Each desiccant dehumidifier is provided with two separate air flow ducts for process and regeneration air with one fan each. The process air to be dehumidified is sucked in by a fan and flows through the dehumidification sector of the continuously rotating desiccant wheel. There the contained moisture is withdrawn by the sorbent and in the further course the dried air flows towards the air outlet.

The regeneration air is also sucked in by a separate fan and guided through the purging sector. Seeing as the desiccant wheel heats up due to the released desiccation heat and the regeneration heat, the purging sector serves for heat recovery and for cooling the desiccant wheel. This leads to a reduced energy input and an improved dehumidification performance alike – especially at lower dew points.

Whilst flowing through the heater battery the air is heated up substantially, in the course of this the relative humidity is extremely reduced. As a result, the air passing through the regeneration sector again absorbs the moisture retained by the silica gel and can then be discharged to the outside as extremely humid regeneration air through the humid air outlet.

All industrial desiccant dehumidifiers of the TTR series operate according to the TTR Trisorp Dual principle of operation with separate air flows of process and regeneration air implemented by one fan each as well as a respective purging sector for the heat recycling process of the incoming regeneration air.

Diverse application possibilities

Owing to their high dehumidification performance during continuous operation – even at low dew points – the industrial desiccant dehumidifier TTR are suited for manifold fields of application, for example:


Can optionally also be supplied as hiring model

Also available as hiring model

As an additional equipment option, a large variety of TTR industrial desiccant dehumidifier is also available as hiring models. Accommodated in a galvanized, stackable transport frame providing shock protection, these models come equipped with crane eyes and forklift pockets on all sides. Upon request the transport frame can further be fitted with additional castors.


Upon request, we also produce customized desiccant dehumidifiers as special models

Upon request, we will readily produce tailor-made desiccant dehumidifiers as special models “made in Germany” perfectly geared to your needs, e.g.:

  • TTR industrial desiccant dehumidifiers with hygienic design
