For
larger Ah capacities, above 500 NM3/hr, we
recommend Model -AA. It is a
skid mounted unit consisting
of Air-Freon chiller, Air to Air pre-Cooler and a moisture
separator. First air is precooled with outgoing chilled air
to around 25°C and then it is cooled in a freon cooler to
{+) 3°C temperature. This reduces refrigeration load of the
Unit. Outgoing dry air has (+) 3°C Pressure Dew Point and
comes out at around 25°C temperature. (+) 3°C Dew Point in
Refrigerated Air Dryers corresponds to around (-) 23°C Atmospheric
Pressure Dew Point. Still lower Dew Point ls not possible
from Refrigerated Dryer as moisture condensed would start
freezing on freon tubes if lower dew points are tried.
(-) 23°C is the best possible Dew Point achievable from Refrigerated
Air Dryers. |
