The TTR400 is a large capacity single drying absorption dehumidifier equipped with the advanced electronic Monoventic air volume regulation, allowing stepless, demand-oriented regulation of the required dry air volume. Compared with the smaller TTR200 and 300 models, the TTR400 has greater drying and airflow and pressure performance. It also utilises the Trisorp Mono system which features a fan in front of the rotor for both air circuits, with a purging sector for the heat recycling process for the incoming regenerated air.

Standard on the TTR400 is an integrated DIN socket which allows for remote switching control of the TTR400 by using an optional hygrostat, time clock or other external switching devices with matching DIN plug. Also a range of TTR accessories are available including hose or pipe connections that can be connected to the regeneration air inlet on the TTR400 as well as different filters for separate air supply.

The TTR400 is suitable for commercial and industrial applications, for protection against condensation in waterworks and pump stations, for anti-corrosion, sandblasting and corrosion protection work as well as for applications in the building industry. It is also suitable for flood restoration in low temperature climates.
