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.
4Warranty
If the equipment fails, please contact M&C directly or else go through your M&C authorised dealer.
We offer a one year warranty as of the day of delivery as per our normal terms and conditions of sale, and
assuming technically correct operation of the unit. Consumables are hereby excluded. The terms of the warranty
cover repair at the factory at no cost or the replacement at no cost of the equipment free ex user location.
Reshipments must be sent in a sufficient and proper protective packaging.

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.
