Desiccant dehumidifiers TTR 500 D

Our powerful mobile TTR dehumidifier: the TTR 500 D with Duoventic. Simply convincing!

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!

Double flexibility thanks to Duoventic

All TTR-D models are also equipped with the advanced Duoventic air volume regulation which allows independent, infinite, electronic control of both fans of the separate air circuits.

Duoventic therefore allows you to separately fine-adjust moisture content and volume flow of the required dry air without the need to install energy-wasting throttle valves, for example, as it had often been necessary in the past.

Thanks to Duoventic, you can always use the full potential fast and demand-orientedly without any conversions while at the same time configuring every climate scenario with only one device:

Extremely dry air with a low air flow, larger volumes of dry air or maximum circulating air performance with a moderate ratio of dry air.

A standard DIN socket for external switchings allows to control the TTR 500 D by means of an optional hygrostat, time clock or other external switching devices with matching DIN plug.

In addition to integrated heat recovery, the standard equipment of the TTR 500 D dessicant dehumidifier also includes a self-regulating electronic regeneration air heating consisting of thermistor elements (PTC) whose performance capacity depends on air inlet temperature and regeneration air volume.

The advantage of this solution lies for one in an optimal performance matching and in the fact that overheating is not possible, making a safety thermostat superfluous.

The standard operating hours counter of the TTR 500 D is optionally available as a dual counter for operating and kilowatt hours:

A few practical benefits:

  • Professional quality „made in Germany“ –
    Originally produced by Trotec
  • Duoventic air volume regulation: Advanced control electronics allow a infinite, separate adjustment of the moisture content and volume flow of the required dry air.
  • TTR Trisorp Dual principle of operation with two separate air circuits for pressure-tolerant recirculation mode for power-saving dehumidification at an increased drying rate
  • Up to 30 % lighter than competitive models with the same performance
  • Maximum of performance with minimum of dimensions and weight
  • Extremely low in maintenance
  • Stackable to save space
  • Tried and tested German industrial design – protected prototype

The TTR 500 D is also the perfect solution to be installed in intermediate ceilings. Due to the wide range of TTR system accessories, hose or pipe connections can be connected to the regeneration air inlet on the TTR 500 D or different Z-line filters of different filter classes can be used for the dehumidifier for separate air supply.

All filters can be changed quickly and easily without opening the device.

Flexible possibilities of use and adjustable, pressure-tolerant recirculationare combined with higher energy efficiency and lower drying stages as well as the advanced Duoventic air volume regulation. Used with components from the wide range of available system accessories, the TTR 500 D desiccant dehumidifier is therefore a universal dryer for most diverse drying applications in industry, logistics, supplies and building sector.

With the TTR 500 D you can benefit from a professional desiccant dehumidifier originally produced by Trotec which has been developed and manufactured according to the highest of quality standards in Germany.
