3Safety instructions
Follow these basic safety procedures when mounting, commissioning or operating this equipment:
•These instruction manual points out the basic dangers when handling the cooler. Further system-related
hazards may occur in individual cases, which the operator must evaluate according to his hazard
assessment - and take appropriate measures.
•Read the instruction manual before commissioning and use. The notes and warnings in the operating
instructions must be complied with.
•When connecting the cooler, ensure that the correct pressure ranges are used in accordance with the type
plate specifications or technical data.
•Before opening the cooler, it must be depressurized. This also applies to any external connections that may
be connected.
•Only use the cooler within the permissible temperature and pressure ranges. The permissible temperature
and pressure ranges are described in the corresponding technical data.
•Ensure that the device is installed in a weather-protected location. Do not expose directly to rain or liquids.
•The cooler must not be operated in potentially explosive atmospheres; The cooler must only be operated
with sample gas according to the analysis questionnaire.
•The cooler must not be operated in potentially explosive atmospheres; The cooler must only be operated
with sample gas according to the analysis questionnaire.
•If the cooler is used to cool gases that are harmful to health, appropriate safety measures must be taken in
the event of leaks (e.g. leaking connections). The personal protective equipment must be adapted to the
hazards at the place of installation and sampling.
•The cooler must be adequately protected against corrosive influences, shocks and impacts to prevent
leakage and component failure.
•Inlets and outlets of the cooler must be provided with protective plugs. This measure is necessary to protect
the interior from corrosion and to prevent the escape of residual liquid or the ingress of foreign bodies.
•Only gases which cannot react with each other or with the material of the cooler or the connections in any
form can be cooled in the cooler.

6Introduction
The M&C gas coolers LGC-1 (with cooling coil for sample gas), LGC-1S (with longer cooling coil for sample gas) and
LGT-2 (with tube bundle for sample gas) are used in analytical technology to lower the dew point of humid sample
gases.
The M&C liquid coolers LC-1 (with cooling coil for liquid sample), LC-1S (with longer cooling coil for liquid sample)
and LTC-1 (with tube bundle for liquid sample) are used to reduce the temperature of liquid media.
Water, for example, is used as the coolant. The counterflow principle used ensures maximum cooling effect.
6.1 Serial number
The type plate with the serial number is located at the side panel of the cooler housing. Whenever you call M&C
regarding questions or orders for the spare parts please give us the serial number of the device.
7Description
The M&C gas coolers LGC-1 and LGC-1S are designed with a cooling coil fully welded in the jacket tube. The LGC-
1S version is equipped with a longer cooling coil.
An integrated separation chamber in the lower part of the gas cooler ensures optimum condensate separation.
In the LGT-2 gas cooler, the sample gas flows through a tube bundle; here, too, there is a separation chamber in
the lower part of the gas cooler for condensate separation.
Figure 1 Gas cooler LGT-2 with tube bundle for the sample gas
A dial thermometer is positioned in the coolant inlet of the gas cooler (coolant IN), which can be used to indicate
the gas outlet dew point.
The condensate produced is discharged externally by using peristaltic pumps, traps or collecting vessels.

The M&C liquid coolers LC-1 and LC-1S are designed with a cooling coil fully welded in the jacket tube. The LC-1S
version is equipped with a longer cooling coil.
Figure 2 Liquid cooler LC-1 with cooling coil for the liquid sample
A dial thermometer is positioned in the coolant inlet of the LC-1 and LC-1S liquid coolers (coolant IN).
In the LTC-1 liquid cooler, the liquid sample flows through a tube bundle. There is a distribution chamber in each
of the inlet and outlet areas of the tube bundle. The distribution chamber in the upper part of the tube bundle is
screwed to the liquid cooler and can be detached.
The dial thermometer of the LTC-1 liquid cooler is located in the sample outlet (see Figure 6). The dial thermometer
can be used to indicate the sample outlet temperature.
The gas and liquid coolers of the LC, LG and LT series operate with low maintenance.
The cooling effect and the stability of the cooling depend, among other things, on the coolant inlet temperature,
the coolant quantity, the sample inlet conditions, the aggregate state of the liquid sample to be cooled, ∆T
between coolant inlet temperature and sample outlet temperature as well as the ambient temperature.
The existing coolant quality and the liquid sample to be cooled must correspond with the material specification
of the cooler.

9Reception and Storage
Note
The cooler must be stored in a weather protected frost-free area!
During transport and storage, the cooler
should always be positioned and stored
according to the position indicated on the packaging.
10 Preparation for Installation
Select the optimum installation site in accordance with the generally applicable guidelines or consult the
responsible authorities. The installation of the cooler must be planned by the installer or operator.
Ensure that the cooler is easily accessible so that any maintenance work that may be necessary later can be
carried out without any problems.
11 Mounting the Cooler
The cooler is designed for stationary use and, if properly selected and installed, guarantees long service life and
minimum maintenance.
Shut-off control devices must be provided by the customer in the inlet of the coolant and the sample to be
cooled.
Note
Ensure the tightness of the tube fitting!
Check the tightness of all tubes after they have been connected.
Do not reduce the specified condensate tubing cross-sections. Reduced cross-
sections might impair the condensate drainage (if present).
12 Connecting Coolant and sample to be Cooled
Warning
Incorrect pressure can destroy the cooler.
When connecting, pay attention to the correct pressure specifications
according to the technical data and the type plate!
The device must be grounded and the potential equalization with the system
must be established.
Connect the coolant and the sample to be cooled according to the technical data and the drawings in chapter 8.

13 Commissioning
Qualified personnel
The work described in this chapter needs to be performed by qualified
personnel. The following minimum knowledge is required for the work:
•Instructed person in the process engineering field.
•
Detailed knowledge of the operating instructions and the applicable
safety regulations.
Note
Check the tightness of the tube fitting!
If necessary, include the tightness of the tube fittings in the maintenance
cycle.
Warning
If toxic or oxygen-displacing gases are cooled with the cooler, the gas paths
must be purged with inert gas or air before opening the gas-carrying parts.
The cooling circuit should always be connected and put into operation first,
and then the sample circuit.
Caution hot surfaces possible!
If hot media are fed through the cooler, the operator must check whether the
external surfaces are to be marked with the "Caution hot" pictogram.
Furthermore, the work safety regulations of the operator must be observed.
Before commissioning, check that the pressure specification corresponds to the specifications on the type plate.
13.1 Setting the Temperature
To set the desired temperature, proceed in the following order:
1. Apply the coolant.
2. Apply the sample to be cooled.
3. Wait until a stable temperature has been reached.
4. Increase or reduce the coolant quantity to set the desired temperature.
Warning
For temperatures > 95 °C, a sufficient coolant flow must be ensured.

16 LC, LG, LT | 1.00.01 www.mc-techgroup.com
14 Closing Down
Danger
E
scape of potentially harmful gas from open process connections after
disassembly possible.
The relevant safety regulations must be observed for the media to be
conveyed.
Before opening flush the lines with a suitable inert gas.
Aggressive condensate possible!
Chemical burns caused by aggressive media possible!
For general
electrical and mechanical work on the cooler, wear personal
protective equipment (PPE) in accordance with the risk assessment.
Before decommissioning, the cooler should be purged with inert gas or air to prevent condensation of aggressive
