The TTR 500 D dessicant dehumidifier not only impresses with its very good dehumidification performance even at low dew points well below 0 °C but also with maximum versatility due to the TTR Trisorp Dual principle of operation:

Two separate air flows for dry and regeneration air with two separate fans for each circuit allow an efficient pressure-tolerant recirculation when setting up the dehumidifier outside as well as inside the room to be treated.

Variable circulating air drying with the TTR 500 D ensures power-saving dehumidification at an increased drying rate:

Compared to the “outdoor air” supplying the regeneration air, in contrast to conventional through-air operation, up to 30 °C lower dew point temperatures can be achieved with the TTR 500 D for a nominal dry air volume . Therefore, dew points far below 0 °C can be achieved, which results in considerably lower drying stages and in considerably more energy-efficient operation!
