Recommended flex gas line is P/N 263058Bxxx; max. length is 20 ft.
Mass of helium refrigerant in compressor at 1.65 MPa (240 psig): 27 g (0.06 lbs.)
Refrigerant Quality
Required refrigerant for charging is 99.999% pure helium gas with a dew point temperature less
than -60° C (-76° F) at 20.7 bar (300 psig).
PRESERVE YOUR WARRANTY.
Specifications require the use of 99.995%
pure helium gas. Using a lesser quality of helium can damage the system and
void the warranty.
Color Codes
The compressor helium connections are color-coded to match color labels provided with the gas
lines.
SUPPLY (red) - Helium high-pressure gas supply from the compressor to the cold head.
RETURN (green) - Helium low-pressure gas return to the compressor from the cold head.
Optional Spacing
Allow 600 mm (24") space in front of the compressor for access to electrical, water and gas
connections. Allow 600 mm (24") space on the left side (when facing the front) of the
compressor for maintenance of the adsorber.
Maintenance Intervals
Compressor adsorber:
30,000 operating hours
Noise Level
< 70 dB(A) at 1m
Dimensions
