Figure 3 Electric gas cooler ECP20-1 and ECP20-2
The type ECP20-1 Peltier Gas Sample Cooler is supplied completely with an EC Jet-Stream heat
exchanger  made either of Duran glass, stainless steel or PVDF for a maximum flow of 250l/h.
The exchanger is housed for ease of replacement in a thermally insulated cooling block  on the right
hand side of the cooler. From serial nos.: 95... the temperature is measured with a PT100 temperature
sensor and regulated electronically by Peltier Elements on a constant temperature of +5°C.
There are proof-plugs for checking the reference temperature and the current temperature, with an
output signal at 0,1 Volt/°C. (see Temperature Setting and Control).
The type ECP20-2 Peltier Gas Sample Cooler is supplied complete with two EC Jet-Stream heat
exchangers , one non regulated as a pre-cooler and the second regulated as a main cooler for a
maximum flow of 500l/h.
The system ensures optimum cooling of the sample gas and condensate separation.
The heat energy emitted by the cooling system is dissipated via a generously sized cooling fin block
with forced ventilation.
From serial no.: 9008023 the ECP20 coolers are equipped with a change-over switch on the control
board for operation at 230V 50Hz or 115V 60Hz. From serial nos.: 95... the switch is mounted on the
basic circuit board.
