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.

Design

The basic device consists of the following components:

• fans for air transport
  • air filters behind every air inlet
• separate sectors for process air (to be dehumidified) and regeneration air (humid exhaust air)
  • purging sector for heat recovery
• 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
• Depending on the selected options further components are possible (see Technical annex).

During dehumidification the desiccant wheel turns continuously at a low speed (depending on the configuration 2 to 40 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.

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In doing so, the contained moisture is withdrawn by the sorbent (silica gel) and retained (desiccation).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 140 °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.

Design configuration and components

rotor

The desiccant dehumidifier works with a desiccant wheel (rotor A) 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.

Rotor drive

The rotor is driven by an electric gear motor.

The power is transmitted by means of synchronized pulley and timing belt.

Rotor rotation control

The device is equipped with a rotation control for an early recognition of a possible rotor standstill.

Rotor bearing

The rotor is mounted on a stainless steel axle with maintenance-free plain bearing bushes.

Rotor sealing

An automatically clearance-compensating gasket system seals the rotor and the individual air sectors against one another.

Filter

Air filters are located in each individual air inlet – depending on the field of application designed either as coarse or fine filter for removing the dust in the air currents.

Fans

Used are radial fans or mixed-flow fans with energy-saving EC motors. For an easy adjustment of the volumetric flow rates a potentiometer is located behind the front cover. Therefore, the fan speed for process air and regeneration air can be adjusted according to the specifications. Hence, additional throttle valves in the air lines are rendered redundant.

Regeneration air heater

Heating the regeneration air is effected by means of electric heater batteries consisting of individual resistance heating elements. Depending on the dehumidifier model and size of the heater these can be designed as single- or multi-stage versions. The regeneration temperature is regulated by a thermostatic two-step control.

Safety temperature monitors (STW) measure both the regeneration exhaust air temperature (RAL) and the regeneration air temperature heating (RHZ). Primarily the regulation is geared to a preferably constant RHZ. With a decreasing moisture load however RAL might positively rocket, so that the heating is down-regulated before reaching the RHZ. Achieved in this way is an optimum performance adjustment of the regeneration energy to the operating point.

Safety components

In order to protect the basic device from inadmissible temperatures, it comes equipped with the following safety components:

• a differential pressure switch (ΔP switch) to monitor the air flow direction and the flow rate of the regeneration air
• a safety temperature limiter (STB RHZ) to monitor the max. permissible temperature after heating (thermostat maximum)
• a safety temperature limiter (STB RAL) as rotation control for the rotor; it is situated in the exhaust air flow and tripped by an inadmissible temperature rise resulting from rotor standstill
• Depending on the selected options further components are possible (see Technical annex).

Note

If a safety component is tripped, the device will be switched off (STOP), but the overrun will remain active.

Wait until the entire rundown period has lapsed before accessing internal parts of the device.

Electrical system

The entire switching and control technology is located in the integrated electrical control box on the dryer housing. The electrical control box is designed for a high safety standard with protection type IP53 (see Technical annex).

Depending on the model, the terminals for remote monitoring and control can either be accessed via the front cover or the cover of the control box. This is also the place to access the reset buttons of the safety temperature limiters and the potentiometers for fan regulation. The cable gland for the mains feed-in is located at the side of the device. The power supply is connected directly to the terminals of the emergency stop main switch.

Housing

Depending on the model the housing of the dehumidifier is made of galvanized sheet steel or stainless steel sheet.

Options

There are additional options available for the desiccant dehumidifiers of the "TTR..." series (see also chapter "Options" in these instructions).

Transport and installation

Warning

Risk of severe injuries due to falling device.

The device may only be lifted by use of the forklift pockets or lifting straps. Pipe sockets or other attachment parts must not be used as lifting points! The carrying capacity of the lifting gear must be suitable for the weight of the device (see Technical annex).

Optionally the device is delivered with a transport frame incl. crane lifting lugs with holes for crane eyes or similar (see Technical annex).

The following should be observed before transporting the device using lifting gear:

Warning

Risk of death due to suspended loads.

Make sure that nobody is situated in the immediate proximity.

• Only instructed persons are allowed to perform the transport by use of lifting gear.
• Consider the centre of gravity when transporting the load.

Installing the device

• Position the device on firm, dry and level ground. Depending on the floor load capacity a panel for weight distribution is to be provided. A proper foundation is not necessary.
• Avoid slippery and oscillating ground.
• Position the device allowing a sufficient distance for air inlet and outlet and for connecting the air transport lines.
• Make sure there is enough space to operate and maintain the device (see Technical annex).

- Only place the device under a roof. On request devices with a higher type of protection are available for outdoor installation. Make sure that no water can reach the device interior via the air inlet and outlet openings. If required, connect an air transport line to minimize the risk. Optionally the device is delivered with weather protection equipment. Do not expose the device to the weather without this weather protection equipment.

- Ensure a sufficient distance between humid air outlet and air inlet. In case of direct-intake devices the distance between humid air outlet and the suction nozzles should amount to at least 2 m to prevent the humid exhaust air from being sucked right back in.

- The air transport lines must be designed for the available static compression of the fans (see Technical annex).

- The regeneration exhaust air line (C) must be laid with a slight decline (min. 1.5 %) 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 deliberately create a nadir (lowest point) for draining (e.g. using a syphon).

Inserting the air filter

Note

To avoid damages to the device, do not operate the device without inserted air filters!

Prior to installation and switching the device on, check whether all air filters are inserted.

The configuration of Flowmatic S depends on your order.

ZIEHL-ABEGG P ▼ 1=▲

The regeneration air control is configured at the factory and does not require any further adjustment.

Target value control: The process air is set via the "Venti.Proz." potentiometer or an external target value.

Venti.Proz.

Actual value control: Enter the desired target value at the Flowmatic S (▲ / ▼). For this purpose, keep changing the value until the desired value is shown on the display. The Flowmatic S will now adjust the value until the fan has reached its maximum speed.

Venti. Proz. ZIEHL-ABEGG UNIcon 7183 m³/h 4V P -Esc-▲

Setting the target value:

Venti.Proz. Venti.Reg. Zusatzhzg.

The upper "Venti.Proz." potentiometer serves to define the target value for the process/dry air volume in m^3/h . The topmost point roughly marks the regulated nominal air volume and the point in the middle marks the nominal air volume in emergency operation. The points indicate the rough settings for emergency operation (failure of Flowmatic S).

The default values are additionally indicated on a label attached to the Flowmatic S.

The settings for the actual value can be made in the Flowmatic S menu:

graph TD
    A["INFO"] --> B["P↓↑ ESC"]
    B --> C["100 Pa Δp"]
    C --> D["100 Pa Setpoint 1"]
    D --> E["▲▼"]
    F["SETTING"] --> G["P↓↑ ESC"]
    G --> H["100 Pa Setpoint 1"]
    H --> I["▲▼"]
    J["BASE SETUP"] --> K["P↓↑ ESC"]
    K --> L["4.01 Mode"]
    L --> M["▲▼"]
    N["1: 0...200 Pa Measuring Range"] --> O["▲▼"]

Note

If "Base Setup" is displayed, you have browsed too far through the menu. Press the "ESC" button in this case.

1. Press both buttons ▲ / ▼ simultaneously. The "INFO" menu will be displayed.
2. Press the ▼ button until the "SETTING" menu is displayed.
3. Press the "P" button.
4. Press the ▼ button until the "SETPOINT 1" menu is displayed.
5. Press the "P" button. The indication flashes.
6. Use the buttons ▲ / ▼ to reduce or increase the set value as desired.
7. Finally press the "P" button to save the settings for the new target value.

Electric reheater for dry air option

For additional reheating of the escaping dry air.

The electric reheater is integrated in the "dehumidifier" housing part of the TTR.

The reheating temperature is preset at the factory and generally does not require any modification.

The access for setting the temperature "7B2" of the electric reheater is located in the electrical control box behind the right housing cover.

Resetting the safety temperature limiters (STB)

If the temperature limiter has tripped, it must be reset:

1. Open the right control cabinet cover (see Operation chapter in the manual).

2. Unscrew the protective cap of the STB reset device "7B1".

3. The STB can now be reset with a pen or screwdriver.

1. Afterwards, screw the protective cap back on.

Operation without electric heating

Warning of electrical voltage

Work on the electrical components must only be carried out by a qualified electrician!

Should it be necessary to operate the desiccant dehumidifier without the electric reheater, simply reposition the jumper.

The jumper for manual changeover is located behind the front cover on the right-hand side.
