Safety Instructions
To this unit, voltage that would cause electrocution or serious injuries is applied. It is extremely
dangerous to touch the live part inside the unit. Make sure to turn OFF the main power source before
performing installation, maintenance or repair. Contacting the internal parts that are not insulated
may damage human body or equipment.
Connect the earth wire to D type grounding.
Nitrogen gas itself is not toxic to human bodies but it reduces the oxygen level in the atmosphere (the
oxygen concentration of 18% or below is defined as an oxygen-depleted state). Install the equipment
on a well-ventilated place, and add a ventilating fan with a capacity of at least 2000 m3/hr airflow.
Do not stay together with a dewar containing liquid nitrogen in a sealed space, such as an elevator or a
car.
The volume of nitrogen gas is 700 times of liquid nitrogen. Sealing liquid nitrogen in an airtight
space produces high-pressure gas of 700 atm and may result in explosion. Use liquid nitrogen in the
condition constantly open to the air.
2. Danger of oxygen deficiency: Ventilate well.
1. Danger of electric shock: Do not touch the live part.
3. Danger of explosion: Do not seal LN

2 ULVAC CRYOGENICS INCORPORATED
Liquid nitrogen provides temperature as low as -196°C. If liquid nitrogen is directly handled,
frostbites, loss of sight, and others are foreseen. Always wear leather gloves, goggles, trousers
without turnips, etc. to handle liquid nitrogen. In addition, use cautions to liquid nitrogen transport
lines, too. In this unit, there is a part with danger of burns if touched directly. Perform work such as
maintenance or repair at least 30 minutes after the unit is shutdown.
High-pressure helium gas is filled in this unit. When disassembling or disposing of the unit or parts, be
sure to discharge helium (no need to discharge helium for regular maintenance). In addition, never
attempt to install the apparatus under the atmosphere of hydrochloric acid-based, chlorine gas-based,
and other corrosive gases.
4. Danger of burns or frostbites: Never touch high
or ultra-low temperature parts.
5. Danger of explosion: Do not expose to corrosive
gases.

Disposal Considerations
Disposal of industrial waste is regulated by national or local governments. Follow all applicable
local or national laws, regulations or guidelines when disposing our products.
We provide Safety Data Sheet (SDS) of our products upon your request.
Please contact us when necessary.
When the refrigerator unit may have pumped toxic or dangerous gases, you must contact
your safety supervisor at the time of disposal, and follow the instructions to remove
hazardous substances before disposing.

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.
