Model Overview
The PKE 5 Peltier cooler family includes several models which may be distinguished by two criteria:
1) Cooling capacity and maximum ambient temperature
2) Number of heat exchangers
These criteria can be specified in the model number as shown in the table below. Please extract the part
number for the cooler fulfilling your requirements from the type code on page 4.

Description
Technical Specifications for All Models
The PKE coolers are controlled by a microprocessor.
The different operating characteristics of the heat
exchangers are established at the factory.
Menu-guided with three keys it is easily possible to
adapt settings to the specific requirements of any
application.
The outlet dew point can be set within a range of
36 - 68 °F. It is factory preset to 41 °F.
When the warning limits are exceeded (e.g. at start-
up), this is indicated by a flashing display and at the
status contact.
The status contact could be used to control the sample
gas pump so that the gas flow is turned on when the
cooler reaches the desired temperature.
Warning limits for high or low temperature can be set
relative to the chosen outlet dew point
. For low
temperature the range is
2 - 5 °F (minimum 34 °F).
For high temperature it is
2 - 13 °F. Factory preset for
both is 5 °F.
