HYDROGEN DRYER
TURBOGENERATORS
PRODUCT SPECIFICATION
Introduction
BRUSH is a manufacturer of hydrogen cooled and hydrogen and water cooled
generators. As part of the auxillary equipment for the cooling circuit for the
generators BRUSH can also provide hydrogen dryers for humidity removal.
Basic principle of hydrogen dryer
The hydrogen dryer works on the principle of humidity freezing. The dryer forms
part of the gas supply system of the cooling circuit to the generator. Humidity
contained in the hydrogen is passed over evaporator cooling coils where it
becomes frozen. After a cycle time of several hours, the dryer is switched off
and the condensation unit starts to allow the frozen water to collect at the
bottom of the dryer vessel. The water level is monitored by an alarm and then
removed by the operator from the tank.
