The physics department at the
Delft University of
Technology (DUT) conducts
quantum mechanical experiments.

Two Reavell H5417 compressors
help recover up to 95% of the helium
used in its research work.

As well as reducing raw material
costs, the compressors’ regulatedspeed
technology and monitoring
software is helping to lower the
department’s operating costs.

The compressors, with custom
built control and monitoring were
developed by the Dutch Reavell
partner Geveke and are configured to
compress the gas to 200 bar pressure,
which is stored in 250+ storage tanks.

The regulated-speed technology
enables the DUT to fine tune
compressor running hours, reducing
overall energy consumption. The
volume in the low-pressure buffer
balloons can alter according to the
DUT’s liquid helium usage, so the
Reavell/Geveke package was built to
include control software, allowing
compressor use to be tailored to needs.

Oil and moisture separators in the
compressor ensure clean, dry helium.

Jelle Haanstra from DUT explains:
“It is important that the helium gas is
as clean as possible. Oil and moisture
can affect the integrity and safety of
our experiments. We are very pleased
with the quality and reliability of the
high pressure gas produced by the
Reavell machines.”
