Sample gas cooler problems
Problem Cause Solution
No display No power Check power supply
Fuse blown Check fuse and change it if necessary
Cooler not running High temperature at the
compressor casing Wait until cooled off and care for enough ven-
tilation
Status-LED blinks with high
temperature Operational temperature
not yet reached Wait for 20 minutes maximum
Cooling capacity to low, even
though cooler is running Make sure that air can circulate free and that
ventilation louvers are not obstructed
Gas flow / dew point / gas
temperature too high Check application parameters, install
pre-separator
Fan broken Check fan, replace if necessary
Status-LED blinks with low
temperature Control defect Send cooler for inspection
Condensate in gas outlet Condensate flask full Drain flask
Stuck valve in automatic
condensate drain Flush both directions
Cooler overloaded Check limiting parameters
Reduced gas flow Clogged gas path Check / flush heat exchanger
Condensate outlet clogged
by ice Send cooler for inspection
