Information about the device

General description
Dehumidifiers operating on the desiccant principle are used to tackle drying tasks in the field of process engineering,
air-conditioning, on construction sites and for the dehumidification of production and storage facilities, where a particularly low humidity level is required over a broad temperature range.
The desiccation technique enables the safe and economic operation even at low operating temperatures.
The desiccant dehumidifier works with a desiccant wheel
(rotor), which is composed of layers of smooth and corrugated non-woven fabric with chemically bonded silica gel. Thus created is a honeycomb structure with a large number of axial air ducts with a large surface and direct connection to the inner pore structure of the silica gel.
On account of the desiccant wheel’s good mechanical and physical properties no silica gel is discharged. It may be supplied with saturated air with a relative humidity of up to 100 % but not with water drops. The rotor is incombustible.

Design
The general structure of a dehumidification unit is as follows:

  • fans for air transport
  • at least two different sectors for guiding the process air (to be dehumidified) and the regeneration air (moist exhaust air)
  • rotor desiccant wheel for the dehumidification with silica gel
  • drive unit with gear motor, toothed belt pulley and toothed belt
  • heater battery for heating regeneration air

During dehumidification the desiccant wheel turns continuously at a low speed (depending on the configuration 3 to 30 rotations per hour). Via the sectors the desiccant wheel is simultaneously charged with the process and regeneration air so it can constantly absorb and release moisture.

Functional principle TTR 400
Process air
The air to be dehumidified is sucked in by means of a fan and divided into two air flows: process air (4) and regeneration
air (5).
The process air (4) flows through the desiccant wheel’s dehumidification sector (1). In doing so, the contained moisture is withdrawn by the sorbent (silica gel) and retained
(desiccation).
After having passed the sector, the now dried air (6) is emitted to the room.TROTEC TTR 500 D Desiccant Dehumidifier fig 1

Regeneration air
The second air current (5) is guided through the purging sector as regeneration air. This sector serves for the recovery of the desiccation heat generated during dehumidification.
At the same time the desiccant wheel is cooled leading to a reduced energy input and improved dehumidification performance – especially at lower dew points.
Subsequently, the air current is led through a heater battery (7) and heated to approx. 100 to 120 °C (depending on the intake temperature). Simultaneously, the relative humidity is extremely reduced.
In passing through the regeneration sector (2), the thus prepared air now again absorbs the moisture retained by the silica gel (desorption). Then the extremely humid regeneration air (8) is discharged to the outside via the humid air outlet.TROTEC TTR 500 D Desiccant Dehumidifier fig

Functional principle TTR 400 D / TTR 500 D
Process air
The air to be dehumidified is sucked in by means of a fan. The process air (4) flows through the desiccant wheel’s dehumidification sector (1).
In doing so, the contained moisture is withdrawn by the sorbent (silica gel) and retained (desiccation). Due to physical processes the temperature of the dry air (6) increases. Later the dried air flows towards the dry air outlet.

Regeneration air
The regeneration air (5) is also sucked in with its own fan and guided through the purging sector (3). During dehumidification the desiccant wheel warms up as a result of the released desiccation heat and the regeneration heat. The purging sector (3) serves the purpose of heat recovery and for cooling the desiccant wheel, leading to a reduced energy input and improvement of the dehumidification performance – especially at lower dew points. Whilst flowing through the heater
battery (7) the air is heated to approx. 100 °C to 120 °C
(depending on the intake temperature) and at the same time the relative humidity is extremely reduced.
In passing through the regeneration sector (2), the thusly prepared air now again absorbs the moisture retained by the silica gel (desorption). Then the extremely humid regeneration air (8) is discharged to the outside via the humid air outlet.

Transport and installation

To make the device easier to transport, it is fitted with a carrying handle.

  • Note
    If you store or transport the device improperly, the device may be damaged.
    Note the information regarding transport and storage of the device.

  • Note
    Device may be damaged by vibration!
    Excessive vibrations can result in damage to the device.
    Therefore, protect it against excessive vibrations, e.g. abrupt positioning or dropping, during transport. Always protect the device from slipping during transport.
    Only lift or carry the device at the provided fixtures.

Positioning

  • Inside the room to be dehumidified:

    • The device works in recirculation mode, the regeneration air must be fed from outside and the regeneration exhaust air must be led outside.
  • Outside the room to be dehumidified:

    • The device can be connected in either recirculation or ventilation mode. A connection of the dry air to the room to be dehumidified must be established.
  • Storage
    When the device is not being used, observe the following storage conditions:

    • dry and protected from frost and heat
    • in an upright position where it is protected from dust and direct sunlight
    • with a cover to protect it from invasive dust, if necessary
    • When not in use, always disconnect the device from the power supply.
    • Up to 4 devices may be stacked on top of one another to save space.
    • Secure stacks against toppling over.

Assembly and installation

  • The pipes or hoses used must be designed for the available static compression of the fans. The air hoses should preferably be laid in a straight line and at full length.
  • The regeneration exhaust air line must be laid with a slight decline so that possibly accumulating condensate cannot flow back into the device or obstruct the air flow. If an incline cannot be avoided, it is necessary to establish a condensate drain. As preventive action, the exhaust air pipe may be insulated.
  • To prevent an immediate neutralization with the moist exhaust air, the humid air outlet should be guided away with a minimum distance of approx. 1 m in case of direct-intake devices.

Scope of delivery
The scope of delivery of the device contains:

  • 1 x Dehumidifier
  • 1 x Connection cable
  • 1 x Instructions

There are further accessories optionally available, which can be obtained from the Trotec customer service.

Default settings
Generally, air conditioning units are equipped with one or more fans, which must be overdimensioned accordingly to overcome resistances caused by pipes or appliances. Usually, their speed cannot be adjusted. In order to set the air quantities required for the application, a hydraulic compensation must be carried out by means of throttle valves installed in front of or behind the fan. This, however, results in an unnecessary and often considerable increase in the noise level and energy consumption.
This device has one integrated variable-speed high-performance fan for each air current supplying the nominal volumetric flow rates of the dry air and regeneration air at maximum speed despite the air hoses (approx. 10 m length each) being connected.
Moreover, for heating the regeneration air, the device has an installed heater battery generating heat by means of ceramic PTC semiconductor elements. The latter have a maximum surface temperature of approx. 240 °C, which they try to maintain. The temperature-dependent resistance, which rises rapidly as of a certain value (Curie temperature) when the heat reduction decreases, causes self-regulating effects of the heating current consumption, i.e. when the air temperature rises and/or the air volume decreases, the current consumption is reduced (and vice versa). Furthermore, a destruction caused by overheating, for instance due to a lack of regeneration air, can be virtually ruled out.

In order to reach a preferably low outlet humidity level with a minimum dry air volume or to achieve the highest dehumidification performance with a maximum dry air volume, it is important to set the regeneration air volume correctly. The air volume must be adjusted until the value specified as optimum heating current is indicated on the ammeter.
For all other applications with low requirements regarding the dehumidification performance and dry air volume, the fan speed may be decreased until the value specified as minimum heating current is indicated on the ammeter. This allows you to achieve very good dehumidification results at minimum energy input.

Filter change

Warning
Risk of injury due to fan!
Make sure to switch the device off and secure it against unintentional start- up before you remove the air filter – especially if the fan’s inlet opening is freely accessible.

The filter change intervals depend on the degree of air pollution and the filter quality. Dirty filters impair the performance ability of the dehumidifier. For this reason, they should be checked once a week (or daily in construction areas) and cleaned or replaced if required.

  1. Pull the filter cover off with a slight jerk and remove the filter mat.
  2. Clean the filter using a slightly damp, soft, lint-free cloth.
    If the filter is heavily contaminated, clean it with warm water mixed with a neutral cleaning agent.
    Info
    Ex factory the device comes equipped with a reusable filter mat (PPI30). It can be cleaned by tapping and washing it out.
    Allow the filter to dry completely. Do not insert a wet filterTROTEC TTR 500

    Note
    Device may be damaged by liquid.
    Before reinserting the air filter, make sure it has dried completely. Otherwise there is a risk of the fan sucking in liquid leading to a short circuit and consequential damage.
    Reinsert the air filter into the device.

Harmful influences on rotors

Some of the substances and compounds listed below are typical examples for substances dissolving the honeycombed silica gel rotors or else negatively affecting the dehumidification performance.
The sorption rotor should not be charged with air which is contaminated with the following or similar substances. Even minor concentrations in the air can have lasting harmful effects on the rotor material and the sorption capacity.

The listed substances remain in the rotor material or the rotor elements and can bring about the following effects:

  • Reduced performance owing to the clogging of the silica gel’s pores
  • Reduced performance owing to the chemical reaction with the silica gel

Moreover, the intake air must not contain any particles of substances with a melting point of less than 200 °C.
