Industrial desiccant dehumidifier TTR 3700

The stationary adsorption dryer TTR 3700 convinces with 492 kg / 24h dehumidifying performance

Even 500 kilogrammes of dehumidification performance per day present no challenge for the TTR 3700 – not even in cold ambient conditions with low dew points. Therefore the industrial desiccant dehumidifier is ideally suited for the most diverse air and gas dehumidification tasks in industrial, haulage or the utility companies , for instance to secure products and production, for the value retention of machines, inventory and buildings through constant protection against corrosion, condensation or mould formation.

With the standard stainless steel housing and an electrical control box with protection type IP44 the corrosion-proof TTR 3700 withstands even the harshest of environmental conditions and is therefore ideally suited for all applications related to dry keeping or the production of dry air at low temperatures or under particularly material-straining conditions – also in hygiene-sensitive areas.

It is no coincidence that with the TTR 3700 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.

Industrial desiccant dehumidifier TTR 3700

Comprehensive standard equipment emphasizes the excellent value-for-money ratio of this industrial desiccant dehumidifier: Be it electronic regeneration heating, rotation control, overtemperature protection system with restart lock, operating temperature management, G4 air filters in Z-line design with electronic monitoring and collective warning light, terminals external On/Off, terminals hygrostat or potential-free contacts for operation, fault and filter – already ex works the TTR 3700 has many practice-oriented equipment features and thanks to numerous equipment options can moreover be equipped precisely to meet your individual needs.

Owing to the integrated Duoventic air volume regulation the TTR 3700, working according to the TTR Trisorp Dual principle with dual air circulation for pressure-neutral recirculation operation, can further be adjusted precisely to the required degree of humidity and the dry air volume. For this purpose using Duoventic two separate fans can be controlled independently via an infinitely variable electronic regulation. As a result there is no need to install any energy-wasting throttle valves for air volume regulation.

Also available as hiring model

TTR 3700 as optional hiring model

As additional equipment option this industrial desiccant dehumidifier is also available as hiring model. Accommodated in a galvanized, stackable transport frame providing shock protection, the TTR 3700 comes equipped with lockable swivel castors at the front and trestle rollers at the rear.

A few practical benefits:

  • Professional quality “made in Germany” – originally produced by Trotec
  • High dehumidification performance even with low dew points
  • Robust stainless steel housing with IP44 type of protection
  • Reliable silica gel sorption rotor
  • Configurable air direction reversal (conversion requires minimal effort)
  • Duoventic control – the performance of each fan can be set individually via a potentiometer
  • Electric regeneration heating
  • Filter monitoring (per air current and collective warning light)
  • Can be configured individually for any application due to manifold equipment options

Configurable air direction reversal

Configurable air direction reversal

Another practical detail for stationary industrial applications, especially with pipe connections, is the configurable air direction reversal of the TTR 3700, for especially in those cases it must be possible to integrate new or additional devices flexibly into existing process sequences.

With the operator side always facing the user, the air flow direction can easily be adjusted to your individual procedures as needed by means of a modular conversion. Blowing out dry air to the right and discharging humid air to the left – or the other way round – with the TTR 3700 the air direction reversal can be carried out with minimal effort.
