1 Introduction

1.1 Intended use

This unit is intended for industrial use in gas analysis systems. It's an essential component for conditioning the sample gas to

protect the analysis instrument from residual moisture in the sample gas.

This device may be operated in a zone 2, explosion class IIC (ATEX & IECEx), explosive gas atmosphere which is rarely and only

temporarily explosive and in Class I, Division 2 (US & Canada).

Optional mounting of various add-on units may limit the area of application of this device.

Cooler with certificate Canada and IECEx

The equipment shall be mounted within a tool-secured IP54 enclosure.

Cooler with certificate USA

The equipment shall be mounted within a tool-secured IP54 enclosure which is capable of accepting one or more of the

ClassIDivision2 wiring methods per the National Electric Code (ANSI/NFPA70).

Cooler with certificate ATEX

The equipment shall be mounted within a IP54 enclosure in accordance with EN60079-15, and in a tool-secured enclosure which

meets the requirements of EN60079-0 and EN60079-15.

Please note the specifications in the data sheet on the specific intended use, existing material combinations, as well as pressure

and temperature limits.

1.2 Overview

The TC-Double X2 series was designed specifically for high cooling capacities, high ambient temperatures and to cool in two

cycles to minimise wash out effects. The two cooling blocks on the TC-Double+ X2 can be set do different temperatures.

Any other use of this cooler is determined by the type of built-in passive pre-cooling, i.e. the first cooling level is not controlled

electronically.

The Peltier cooler is distinguished by two types according to cooling capacity or operation temperature. This classification is re-

flected in the type designation. The exact item number of the model defined by you is determined by the model code in the cat-

egory ordering information.

2 heat exchangers in series TC-Double 6111 X2 TC-Double 6112 X2

2 heat exchangers in series TC-Double+ 6111 X2 TC-Double+ 6112 X2

Additional components which every conditioning system should feature can optionally be integrated:

– Peristaltic pump for condensate separation,

– Filter,

– Moisture detector,

– Sample gas pump.

This allows for various configurations of cooler and options. Here the approach is to simplify creating a complete system in a

cost-efficient way through pre-installed components with hoses connected. We further paid attention to easy access to wear

parts and consumables.

4 Installation and connection

4.1 Installation site requirements

The unit is only intended for wall-mounted use in enclosed areas. Adequate protection from the weather must be provided

when used outdoors.

Install the unit leaving enough room below the cooler to discharge the condensate. Leave room above for the gas supply.

Be sure to maintain the approved ambient temperature. Do not obstruct the convection of the cooler. The vents must have

enough room to the next obstacle. The distance must especially be a minimum of 10 cm on the air outlet side.

Ensure adequate ventilation when installing in enclosed housings, e.g. analyser cabinets. If the convection is inadequate, we re-

commend aerating the cabinet or installing a fan to lower the inside temperature.

4.2 Installation

Run the gas supply to the cooler with a downward slope. The gas inputs are marked in red and additionally labelled “IN”. The op-

timal gas connection is detailed in chapter Connecting the heat exchanger.

If a large amount of condensate accumulates, we recommend using a condensate trap with automatic condensate drain before

the cooler.

Glass vessels and automatic condensate drains are available for draining condensate for external mounting below the unit.

When using automatic condensate drains, the sample gas pump must be installed ahead of the cooler (pressure operation) to

ensure proper function of the condensate drain.

If the sample gas pump is located at the cooler outlet (suction operation), we recommend using glass condensate traps or peri-

staltic pumps.

Connecting the condensate drains

Depending on the material, build a connecting line with fittings and tubing or hose between the heat exchanger and condens-

ate drain. For stainless steel the condensate drain can be suspended directly to the connecting tube, for hoses the condensate

drain must be secured separately using a clamp.

The condensate drain can be mounted directly to the heat exchanger.

Condensate lines must always be installed with a slope and a minimum inside diameter of DN 6/8 (1/4”).

4.2.1 Flow adapter connection (optional)

When ordering the cooler with the

option moisture detector without filter

, it will be factory installed inside a flow adapter.

The connection between the heat exchanger outlet and the flow adapter inlet does not have tubing included. The connection

G1/4 or NPT1/4" (flow adapter marked NPT) for the gas inlet/outlet must be carefully and properly connected using a suitable

screw connection. Here the direction of flow is not relevant.

4.2.2 Connecting the moisture detector (option)

When ordering the cooler with

moisture detector option

, it will be factory installed inside a flow adapter, or for the

filter option

installed and connected in the filter head.

4.2.3 Connecting the peristaltic pump (option)

Coolers ordered with attached peristaltic pump already have it installed and wired. Heat exchangers ordered at the same time

are already installed and connected to the peristaltic pump.

The connection via the condensate outlet screw connection on the pump must be carried out carefully and properly.

TC-Double (+) X2

4.2.4 Sample gas pump connection gas lines (optional)

On coolers ordered with attached sample gas pump these are already installed and wired. Add-on parts ordered at the same

time are already installed and connected to the sample gas pump.

Avoid mixed-material installation, i.e. metal piping to plastic bodies. If this cannot be avoided in isolated applications, screw the

metal connections into the pump body with care, never use force.

Lay the lines so the line at the inlet and outlet remains flexible for an adequate distance.

The pumps are marked

for inlet and

OUT

for outlet at the mounting ring. Be sure the gas line connections are tight.

4.2.5 Connecting the heat exchanger

To minimise gas wash out in the cooler, the two (identical) heat exchangers must be operated in series. This should be done as

follows:

1. Gas inlet line to red gas inlet on heat exchanger no. 2 (pre-cooling).

2. Connection between the heat exchanger no. 2 gas outlet and the red gas inlet on heat exchanger no. 1 (after-cooling).

3. Secure final gas outlet line to the heat exchanger no. 1 gas outlet.

4.3 Electrical connections

The operator must install an external separator for the device which is clearly assigned to this device.

This separator

– must be located near the device,

– must be easy for the operator to reach,

– must comply with IEC 60947-1 and IEC 60947-3,

– must separate all live conductors and the status output, and

– must not be attached to the power feed.

The mains supply of the device must be fused according to the specifications under technical data.

Potential equalization/static charge

Static charges can result in incendive sparking. Avoid static charges. Any conductive parts of the cooler must be grounded!

The housing has a connection for an earth/equipotential bonding conductor. Ensure the housing is adequately earthed (min-

imum conductor cross-section 4 mm

Particularly observe the requirements of EN 60079-14!

WARNING Hazardous electrical voltage

The device must be installed by trained staff only.

CAUTION Wrong mains voltage

Wrong mains voltage may damage the device.

Regard the correct mains voltage as given on the type plate.

If the option “temperature signal” is built in, the unit has a signal output via the analogue output to indicate the actual cooler

temperature.

The temperature signal can be read via the panel plug (S3) using the M12x1 connector. This plug is located next to the moisture

detector connectors at the top of the cooler.

The temperature (CH1) which continuously appears in the display corresponds to the temperature in block 1 (after-cooling). The

analogue temperature signal also corresponds to the temperature in block 1.

5 Operation and control

NOTICE

The device must not be operated beyond its specifications.

After switching on the cooler the block temperature will be displayed (block 1). The display will flash until the block temperature

has reached the preset target value (± adjustable alarm range). The status contact is in the Alarm position.

Once the target temperature range has been reached, the temperature will continuously be displayed and the status contact

switches over.

If the display flashes during operation or an error message appears, please refer to bullet “Troubleshooting”.

Please refer to the data sheet for performance data and maximum ratings.

5.1 Description of functions

The cooler is controlled by a microprocessor. With the factory preset the control already incorporates the various characteristics

of the built-in heat exchangers.

The programmable display shows the block temperature in the selected display unit (°C/°F) (factory preset °C). Application-spe-

cific settings can easily be configured guided by the menu, using the 5 buttons. For one, this applies to the target outlet dew

point, which can be set from 2 to 20°C (36°F to 68°F) (factory preset 5°C/41°F).

And then the warning thresholds can be adjusted for low and excess temperature. These are set relative to the outlet dew point

setting.

For the low temperature the range is τ

-1 to - 3K (at a minimum 1°C/ 34°F cooling block temperature), for the excess temperat-

ure the range is τ

+1 to +7K. The factory presets for both values are 3K.

The flashing display and the status relays indicate the conditions are below or above the configured warning range (e.g. after

switching on).

The status output can e.g. be used to control the sample gas pump to allow for the gas flow to only be switched on once the per-

missible cooling range has been reached or shut off the pump in the event of a moisture detector alarm.

The separated condensate can be drained via connected peristaltic pumps or add-on automatic condensate drains.

Fine mesh filters can also be used, which in turn can be installed in optional moisture detectors.

The glass dome allows the dirt level of the filter element to easily be determined.

The moisture detector is easy to remove. This may be required if a condensate enters the cooler due to a malfunction and the

peristaltic pump or the automatic condensate drain is unable to remove it.

The TC-Double has an additional cooling stage for pre-cooling the gas (heat exchanger 2), the block temperature of which varies

by ambient temperature and load. The target value of the pre-cooling stage corresponds to that of block 1.
