All mobile adsorption dryers of the TTR series are produced by Trotec in Heinsberg: TTR 200, TTR 300, TTR 400/TTR 400 D and TTR 500/TTR 500 DThanks to high-quality components and an innovative housing design the new TTR air dehumidifiers are the lightest machines of their performance class.Despite the light design the powder-coated steel sheet construction is extremely durable.Two instead of one fans are installed in the TTR 400 D - as a "double blower" it is particularly strong.All TTR desiccant dehumidifiers have silica gel sorption rotors to savely protect the rotor against steam or water.In our production in Heinsberg we rely on the experience of qualified employees - paired with the innovative strength of the product developers.Our technicians check the functionality of every single device of the TTR series before it is brought to stock, to one of our branch offices or delivered to a customer.Tried and tested German industrial design - the robust housings can be stored side by side as well as on top of each other without any problems.
