RDK Series Gifford-McMahon Cryocoolers are high-quality,
ultra-reliable designs that operate at extremely low
temperatures (typically liquid helium temperatures).
Due to the unique operating environment of these cryocoolers, on-site service
and maintenance non-trained technician from SHI is not recommended at this
time. The most reliable approach to service and maintenance on these
cryocoolers is to return them to our service centers.
We also understand that there are cases where complete removal and return of the cryocooler is overly difficult. In response,
We also offers “Hot Swap” service performed by trained technician from SHI.
Hot Swap service allows for “in situ” maintenance, without the need to remove the complete cryocooler for return or
replacement. Hot Swap service involves complete exchange of the cryocooler assembly, with the exception of the cylinder,
which remains installed in the customer’s system. Hot Swap implies that the customer’s system is warm to allow for reliable
removal and exchange.
RP Series Pulse Tubes are high-quality, ultra-reliable designs
that operate at extremely low temperatures (typically liquid
helium temperatures).
Due to the unique operating environment of these cryocoolers, on-site service
and maintenance non-trained technician from SHI is not recommended at this
time. The most reliable approach to service and maintenance on these
cryocoolers
is to return them to our service centers.
CH and DE Series Cryocoolers can be serviced via “hot swap”
on-site by the customer or a trained technician from SHI,
without removing the cryocooler for return or replacement.
This unique service option is the result of the high-quality, ultra-reliable
Displex® Cryocooler technology found in all CH and DE Series Cryocoolers.
Displex Cryocoolers have a long and successful operating history, and feature
a pneumatic drive that optimizes performance and reliability and permits quick
and easy removal of the displacer assembly for maintenance.
