The Signal Group 250 Portable cooler dryer removes water vapour from stack and exhaust emission gases, before analysis by ambient analysers.
The 250 features a semiconductor Peltier cooling system with an aluminium cooling block. Fitted into the block is then a high efficiency heat exchanger made of stainless steel. The condensed water is then removed using a continuous peristaltic pump.
The status of the cooler is indicated by an LED system with high temperature alarm, a water alarm and an indicator that the set temperature is being maintained.
