Buhler PKE 511, Инструкция по установке и эксплуатации

Страница: 38 / 46

Model Overview
The PKE 5 Peltier cooler family includes several types which may be categorised 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.
The general specifications can be found in the table below. On the next page are the performance curves and the
specifications for each cooler. In the table below that there is an overview of the heat exchanger's data.
Description
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.
Warning limits for high or low temperature can be set
relative to the chosen outlet dew point
. For low
temperature the range is 1..3°C (minimum 1°C / 34°F).
For high temperature it is +1..7°C. Factory preset for
both is 3°C.
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.
The outlet dew point can be set in a range of 2 to 20 °C
(36..68°F). It is factory preset to 5°C (41°F).
When the warning limits are exceeded (e.g. at start-up) this
is signalised by a flashing display and the status contact.
