Meßgaskühler / Sample Gas Coolers PKE-42

Installation and Connection
The PKE-42 sample cooler is to be attached to vertical panels. The heat exchangers either made from
stainless steel, glass or PVDF are inserted from the top. Make sure, that there is enough space left above and
under the cooler to get the pipes/or hoses connected to the unit.
The place of installation must be weather shielded and air shall circulate freely around the cooler. The ambient
temperature shall not exceed the range from +5 to +50°C (+41 to +122°F) for the PKE-42.
Free air circulation must be provided. On both sides a gap of at least 10 cm (4 inches) must be kept clear.
Free air circulation must also be provided if the cooler is installed inside a cabinet. In some cases a fan is nec-
essary to establish sufficient circulation within the cabinet.
3.1 Mounting
Depending on the application parameters the connecting pipes or hoses must be of adequate material and
fastened tight. Connect the hoses to the heat exchangers made of duran glass with care to avoid breaking the
glass.
Make sure that all sample gas lines leading to the cooler are installed with downward slope to enable conden-
sate flow into the heat exchanger by gravity.
In some applications with very high condensate content separators upstream the cooler could become neces-
sary (see catalogue for appropriate types).
The gas entrance is marked with red.
If the sample gas pump is located upstream of the cooler, the condensate can be drained off by automatic
condensate drains. If the pump is located downstream peristaltic pumps or condensate vessels must be used
for removal (see our catalogue for appropriate equipment).
Important:
The PVDF heat exchanger type DTV cannot be used with automatic drainers but with peristaltic
pumps only.
The condensate drains can be attached directly to such coolers with stainless steel heat exchangers. In case
of glass heat exchangers the condensate drains must be connected with flexible lines fixed with by brackets
separately.
The condensate lines must be installed with considerable slope and should not have less than 8 mm (0,3 inch)
inner diameter.
3.2 Electrical
connection
WARNING
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
