R&D/Other Service
SHI’s complete lines of Cryocoolers and Marathon® CP Cryopumps are the preferred choice for numerous research and non-semiconductor vacuum applications.
Whether an SHI product is installed as a bare unit, attached to a vacuum chamber or connected to a complex cryogenic system, we offer several service and support options to meet our customers’ needs.
While particular options vary by product type, all SHI Cryocoolers and Marathon CP Cryopumps feature:
- A reliably long life on rebuilt and repaired products
- Products rebuilt using brand new parts – we don’t salvage parts from other units
- Technical support only the OEM can provide
- Full factory warranty

RDK/E Series Cryocooler Service Options
Product repairs and refurbishments performed at SHI Service Centers include:
- Flow check of all internal parts to ensure optimum refrigeration capacity
- Replacement of required wear items—seals, valve disc, valve stem, capillaries and displacers, when necessary
- Performance testing to factory specification
- Leak check, both pressurized and for vacuum integrity, where applicable
We also understand that there are cases where complete removal and return of the cryocooler is overly difficult. In response, SHI also offers “hot swap” service performed by SHI technicians.
What Is Hot Swap Service?
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 accessible, has any ancillary instrumentation removed in advance, and is warm, allowing for reliable removal and exchange.
Performing hot swap service lowers the total cost of ownership by:
- Eliminating the cost of shipping a complete cryocooler to a service center
- Eliminating labor costs associated with complete disassembly of the cryocooler from your system
- Minimizing the “down time” of your system for service or repair
- Minimizing the required capital investment in spare parts
RP Series Pulse Tube Cryocooler Service Options
Due to the unique operating environment of these cryocoolers, on-site service and maintenance by non-SHI technicians is not recommended at this time. SHI technicians can perform a limited amount of service on-site, including the cleaning and replacement of wear items, gas cleanup and additional tuning. However, the most reliable approach to service and maintenance on these cryocoolers is to return them to one of SHI’s service centers.
Product repairs and refurbishments performed at SHI Service Centers include:
- Replacement of required wear items—valve stem and filter unit, when necessary
- Cryogenic gas cleansing of all system components
- Performance testing to factory specification
- Leak check, both pressurized and for vacuum integrity, where applicable
CH Series Cryocooler Service Options
CH Series Cryocoolers can be serviced via hot swap, either on-site by the customer or by an SHI factory-trained technician, without removing the cryocooler for return or replacement. This unique service option is the result of high-quality, ultra-reliable Displex® Cryocooler technology. 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.
In addition, these cryocoolers can be returned to one of SHI’s service centers. Product repairs and refurbishments performed at SHI Service Centers include:
- Flow check of all internal parts to ensure optimum refrigeration capacity
- Replacement of required wear items—seals, valve disc, valve stem, capillaries and displacers, when necessary
