HXB-V1
10 barg version, one to five units · min. 10 barg at the inlet
The HXD-V1 is a 19-inch 6U modular hydrogen dryer that takes the hydrogen from up to five HXB-V1 units (2.5 Nm³/h) to 99.999% purity, available to order now (lead time confirmed with the quotation).
Two adsorber towers alternate between drying and heater purge regeneration, taking wet hydrogen from the HXB-V1 to a dew point of -65 °C or lower (atmospheric). The adsorbent is sealed and needs no replacement.

Standard · up to 35 barg on request
Hydrogen leaving the HXB-V1 is 98–99% at ambient pressure and 99% at 10 barg without a dryer, and it is saturated with water. The HXD-V1 takes that water out to reach 99.999%. One unit serves one to five HXB-V1 units of the 10 barg version and needs at least 10 barg at its inlet.
A dryer goes in when the application sets a dew point or purity. How far down you dry is what the application decides.
The HXD-V1 removes the water between the HXB-V1 and the storage or end-use equipment. Piping and installation are a separate scope of supply.

Review the internal process first. Open the control app views when you need the operating states and alarms.
The dryer screens are included from app version 2.1.0. The P&ID screen shows readings, valve states and the regeneration step of each tower; Alarms & Events shows ES, FS and WA alarms and the command history, and records export as CSV. Site PLC or SCADA integration uses Modbus TCP. Values on the screens are examples.


The HXB-V1 hydrogen outlet connects straight to the HXD-V1 inlet, and the dried hydrogen goes on to the site equipment. Power and vent lines are prepared on site.

Check the connection conditions and site preparation first. Tell us how many HXB-V1 units you will connect and the dew point and purity you need, and we will review the configuration and quotation.
