3 Installation and Connection
The PKE 5xx coolers are designed for indoors applications. If the device is installed outside provide sufficient
weather protection.
The PKE 5xx sample cooler is to be attached to vertical panels. Provide enough space below the device to
drain off condensate. Above leave some space for providing gas flow.
The allowed ambient temperature shall not exceed the values according to Table 1 on page 19. Free air
circulation must be provided. Leave enough space to any obstacle to the lateral ventilation grilles. Particularly
with regard to the air outlet (on the right) keep a gap of at least 10 cm (4 inches). If the device is mounted
inside closed covers, e.g. cabinets for gas analysis systems, provide adequate air circulation. If convection
alone is not sufficient, rinse the cabinet with air or install additional fans to lower the inner temperature.
3.1 Mounting
With glass heat exchangers, make sure that the gasket is inserted in correct orientation. The gasket consists
of a silicon ring and a PTFE shield. The PTFE shield must point to the glass thread.

Make sure that all sample gas lines leading to the cooler are installed with a downward slope. In some
applications with very high condensate content separators upstream the cooler could become necessary. Best
suited are our fluid separators with automatic condensate drain 11 LD, especially AK20 or type 165.
The gas entrance is marked with red. Connect the hoses to the heat exchangers made of DURAN glass with
care to avoid breaking the glass.
To drain condensate glass vessels or automatic condensate drains are provided for external mounting below
the device. If the sample gas pump is located upstream of the cooler, the condensate can be drained off by
automatic condensate drains.
NOTE
Heat exchangers MTS and MTV (cooler with two heat exchangers) cannot be used with
automatic condensate drains.
