HYDROGEN DRYER
[attachment=60923]
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.
Condensation unit consist of :
• steel sheets, profiles and tubes
• copper sheets, profiles and tubes
• cooling unit Bitzer
• accessories
• type of refrigerant: R 134a
• refrigerant volume: 3.4 kg
Standards and documentation
The hydrogen dryer is manufactured and tested in accordance
with harmonized European standards ČSN EN. The hydrogen
dryer is furnished with nameplate, CE mark, technical
documentation, manufacturer’s Declaration of Conformity and
appropriate quality control reports.
QMS & EMS certification
BRUSH conforms to the Quality Management System Standard
ISO 9001:2000 and the Environmental Management System
Standard ISO 14001:2004.
Compact version of Hydrogen Dryer
All the components are mounted on a single steel frame.
Sensors that monitor parameters on the system are connected
to a control box by cabling. BRUSH complies to the
EN 60079-10, where the distance between dryer vessel and
condensation must be a minimum of 2 meters.
