HXD-V1 · updated 2026-11-11

What arrives and what you prepare, the factory test before shipping, what to check on delivery, the port caps and storage conditions.

How the unit arrives, what to check before you sign for it, and how to keep it until installation. The adsorbent inside is dry when it leaves the factory, so keeping moisture out matters from the first day.

What arrives and what you prepare#

Included#

  • The HXD-V1 itself, with its ports capped
  • The user manual, sent electronically
  • The factory acceptance test document

Prepare separately unless ordered#

  • The Ethernet cable and the AC power cord

Your site provides#

  • A control PC or laptop
  • 1/4-inch stainless steel tube and fittings rated for hydrogen

  • Vent lines that take PURGE and DEPR. to a safe place outdoors
  • A liquid trap for DRAIN
  • Rack rails or a shelf to support the body
  • A dew-point or purity analyser, if you want to read the dew point and did not order the dew point sensor

When HydroXpand supplies the complete rack, the tube, fittings and rack rails are part of the rack integration scope.

Factory test before shipping#

Every HXD-V1 passes the tests below at our factory before it ships. The results go in the factory acceptance test document that comes with the unit, and the first start is compared against them.

AreaWhat is checkedCriteria
BuildEnclosure, wiring, gas fittingsNo damage, missing or loose parts
Electrical safetyProtective earth bonding, insulation resistance (500 V DC)0.1 Ω or less, 1 MΩ or more
SensorsTemperature and pressure sensors against reference instrumentsWithin ± 2 °C and ± 0.2 barg
CommunicationControl app link, CSV logUpdates every second; every channel logged
FunctionsTower switching valves, fans, heaters and contactor, leak-sensor emergency stopEach responds as commanded; the two heaters are never on together
PressureN₂ leak test and pressure hold at 10 barg, relief valve set-pressure certificateNo leaks; relief valve set at 15 barg
Hydrogen run24 h on hydrogen from an HXB-V1 at 10 barg, each tower regenerated onceRegeneration temperature reached, switch at 40 °C or below, outlet dew point -65 °C or below, no drain warnings, no hydrogen leaks
As shippedRegeneration setting, portsFactory setting (150 °C, 12 h cycle, 6 h heating); all six ports capped

Unpacking and inspection#

Before you start#

Have the delivery documents, the order details, a camera, and a lifting aid or a second person ready.

Work sequence#

  1. Look at the outer packaging first.
    • Check for dents, impact and water damage.
    • Note any damage on the delivery documents and photograph it. You will need that for a carrier claim.
  2. Open the box carefully.
    • Keep the blade shallow so it does not damage the port caps or fittings.
  3. Move the unit onto a stable, level surface.
  4. Inspect it by eye.
    • Check the enclosure and handles for dents, cracks and deformation.
    • Check that all six gas ports are capped and that the power inlet and Ethernet port are undamaged.
    • Compare the model and serial number on the label with the delivery documents.

Inspection completion criteria#

The model and serial number match your order, the enclosure, ports and fittings are undamaged, and every port cap is in place.

If a check fails#

Do not install the unit. Send us the photos and the serial number. For transport damage, we also need the note on the delivery documents and the photos.

Storage#

  • Store indoors, dry and frost-free, in the original packaging.
  • Keep the unit level. Do not stack other loads on it.
  • Lift with two people, by the front handles and the base together. The handles alone are not meant to carry the full unit.
