ULVAC CRYOGENICS INCORPORATED 5
General Description of the System
Liquid nitrogen generator (UMP-40W)
UMP-40W Liquid Nitrogen Generator provides liquid nitrogen by cooling down, condensing and
liquefying nitrogen gas with the cold head (RMS150T).
Liquid nitrogen is stored inside dewar, and can be transferred to another container with easy
operation. With the optional automatic transfer system, liquid nitrogen can be automatically
transferred to the dewars of the customer’s system.
Nitrogen gas source can be selected from PSA nitrogen generator, and membrane nitrogen
generator.
Liquid nitrogen generator is hereafter referred to as “UMP-40W” in this book.
Helium gas compressor (C30PMVRT)
This unit is in the right side of UMP-40W, compress Helium gas to supply to the cold head to
provide cryogenic temperatures . It is automatically turned on and off by the control circuit of
UMP-40W.
Helium gas compressor is hereafter referred to as “C30PMVRT” in this manual.
For details of this equipment, please refer to the operation manual for “C30PMVRT”.
PSA (Pressure Swing Adsorption) Nitrogen Generator (type GN-30i)
PSA Nitrogen Generator GN-30i generates highly concentrated nitrogen from the air using
adsorber and supply the gas to UMP-40W. The nitrogen generated here is used as the material
for liquid nitrogen and is also used to take out liquid nitrogen.
PSA nitrogen generator is hereafter called “GN-30i” in this book. When we describe things that
are in common with membrane nitrogen generators, they are collectively referred to as “nitrogen
generators”.
Please refer to the operation manual of GN-30i for details.
