The Trotec TTR 500 D desiccant dehumidifier is a device for humidity control in industrial, logistics, and building environments. Thanks to the TTR Trisorp Dual operating principle, this device uses two separate air circuits – one for dry air and one for regeneration air, each equipped with a dedicated fan. The Trotec TTR 500 D dehumidifier ensures efficient dehumidification at neutral pressure, both in indoor and outdoor installations. Unlike conventional systems, the TTR 500 D can reach dew points up to 30°C lower than the outside air, allowing optimal drying conditions even below freezing. Equipped with Duoventic electronic control , it allows the flow and humidity of the dry air to be managed independently , optimizing performance and energy efficiency. Compact, lightweight, and easy to maintain, the TTR 500 D combines Made in Germany quality with maximum operational flexibility.
The Trotec TTR 500 D is a desiccant dehumidifier designed to deliver high performance even under the most demanding conditions. Thanks to the TTR Trisorp Dual principle, the device works with two separate air circuits and two independent fans . This technology ensures efficient air exchange at neutral pressure, ideal for both indoor and outdoor installations, maintaining constant energy efficiency and ensuring superior drying.


One of the distinctive features of the TTR 500 D is the Duoventic system , which allows the two fans in the air circuits to be electronically and independently controlled. This function allows you to precisely adjust the humidity and dry air flow to your specific needs, eliminating the need for additional valves and reducing energy consumption. Whether you need to generate extremely dry air at low flow rates, large volumes of treated air, or maximum recirculation power, the Trotec TTR 500 D adapts to every scenario.


In addition to its high efficiency, the Trotec TTR 500 D desiccant dehumidifier comes standard with a DIN socket , allowing connection to hygrostats, timers, or external control systems. The self-regulating heater with PTC technology ensures maximum safety, preventing overheating without the need for additional thermostats. Maintenance is simple thanks to the easily replaceable Z-Line filters, while the compact, stackable design facilitates storage and installation, even in suspended ceilings.


Designed and manufactured in Germany according to the highest quality standards , it is an ideal choice for industrial, logistics, and construction applications. Thanks to its versatility and numerous available accessories, this dehumidifier is the universal solution for those seeking professional performance and maximum efficiency.
