As is the case with the 400D, the larger capacity TTR500D features Trisorp Dual system which allows seperate infinite adjustment of the moisture content and volume flow of the required dry air. This system features two seperate air circuits for a pressure-neutral circulatory air operation.

Designed and manufactured in Germany, the secret to the TTR models is the combination of high quality internal components with lightweight yet extremely durable powder coated steel sheet housing.

The TTR models work on the absorption principle where the desiccant silica absorbs the wet air. The damp material is then heated to drive off the humidity. Where refrigerant dehumidifiers do not work well in cold temperatures, absorption type driers can achieve low humidity levels in much colder conditions, well be low 0 degress celcius.

Standard on the TTR500 D is an integrated DIN socket which allows for remote switching control of the TTR500 D 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 TTR500 D as well as different filters for separate air supply.

The TTR500 D 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.
