Keeping humidity perfectly under control

The maintenance-friendly desiccant dehumidifier TTR 800 not only guarantees high dehumidification levels even at very low dew points – with its stainless steel housing and an electrical control box in IP53 design, the corrosion-resistant TTR 800 even withstands adverse operational environments and is therefore ideally suited for a variety of dry keeping tasks or the production of dry air in the chemical, pharmaceutical and food industry as well as in the sector of mechanical engineering, but also to protect machines, inventory and buildings from corrosion, condensation and mould formation, for example in water processing facilities or electrical control centres.

High Performance made in Germany

It is no coincidence that with the TTR 800 you benefit from an equally durable and easy-to-service construction – after all it is a desiccant dehumidifier originally produced by Trotec, developed and manufactured in Germany according to the highest quality standards, which houses only efficient branded components of the latest generation of technology supplied by leading component manufacturers.

For the purpose of dehumidification the desiccant dehumidifiers of the TTR series take advantage of the vapour pressure gradient between the humid air and a hygroscopic sorption agent incorporated in a desiccant wheel with an extremely large surface structure. This procedure ensures a high dehumidification performance even at a low humidity level and low air temperatures.

TTR Trisorp Dual principle

The TTR 800 is provided with two separate air flow ducts for process and regeneration air with one fan each. The process air to be dehumidified is sucked in by a fan and flows through the dehumidification sector of the continuously rotating desiccant wheel. There the contained moisture is withdrawn by the sorbent and in the further course the dried air flows towards the air outlet.

The regeneration air is also sucked in by a separate fan and guided through the purging sector. Seeing as the desiccant wheel heats up due to the released desiccation heat and the regeneration heat, the purging sector serves for heat recovery and for cooling the desiccant wheel. This leads to a reduced energy input and an improved dehumidification performance alike – especially at lower dew points.

Whilst flowing through the heater battery the air is heated up substantially, in the course of this the relative humidity is extremely reduced. As a result, the air passing through the regeneration sector again absorbs the moisture retained by the silica gel and can then be discharged to the outside as extremely humid regeneration air through the humid air outlet.

Diverse application possibilities

Owing to its high dehumidification performance during continuous operation – even at low dew points – the industrial desiccant dehumidifier TTR 800 is suited for manifold fields of application:

• Pre-dehumidification of the conveying air for maintaining the pourability and flowability of hygroscopic products in storage, transport and dosing systems
• Process air dehumidification for gas turbines and humidity regulation in gas distribution stations
• Frost protection in freezing tunnels and cold stores
• Dehumidifying or drying process air in sectors of the chemical and pharmaceutical industry, the electronics and semiconductor industry, or food industry
• Preventing the formation of condensate, material changes or granules from going lumpy during plastics processing
• Process air drying and dehumidification of systems steel industry
• Dry keeping of air and dew point control in cold stores
• Dry keeping of air in water processing facilities and pump stations
• Climate conditioning in ammunition depots or military equipment depots
• Dehumidification and dew point control in cleanrooms and drying rooms
• Climate conditioning in the field of dry air storage or in timber stores
