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.
