Farrar Scientific IntermediatesFarrar Scientific offers the Intermediate line of low and ultra-low temperature servers to take advantage of standardization in core industry markets. Although customer applications are always unique, many custom products possess similar components, controls and design architecture which form prerequisites for end-use systems.
To take advantage of core commonality in low and ultra-low temperature products, and to meet the demand for highly specific products that are built, tested and delivered in relatively short lead times, Farrar Scientific has developed standard server systems manufactured to an intermediate point, placed in inventory, and available for final configuration to match customer specifications and quick turn-around.
Marketed as Farrar Intermediates, the product line includes a selection of conventional and ultra-low temperature platforms, line sets, evaporators and control systems matched to fulfill custom requirements only when orders are received.
Base Servers
The Intermediate base server product line includes several performance groups providing a range of load, Watt@°Temp and BTU/Hr removal capacities. Farrar Intermediate servers are manufactured to a build-out point, paused in production and placed into inventory for retrieval and quick completion to meet individual customer specifications for energy transfer and delivery.
- Base servers are configured from standard air- or watercooled reciprocating compressors, or scroll compressors, depending on performance and energy exchange requirements, voltage and site preferences, and throughput considerations.
- Once the final specifications are received, each server is completed, fully charged, helium leak tested and factory tested to both Farrar Scientific and customer-supplied criteria.

Capturing Energy
Energy exchange points or "transfer nodes" where ultra-low temperatures are applied to the system or process can be designed in a variety of methods. These include but are not limited to:
- Standard manifolds
- Coils
- Milled plates
- Tooling supplied by Farrar Scientific to your specification
- Tooling supplied by you or a third party
Typically, transfer nodes are categorized as:
- Direct exchange
- Chiller
- Storage

Typical Applications |
Plates, manifolds, three-dimensional or molded shapes for high point or large heat loads in a concentrated location. Used for semiconductor and electrical component testing, temperature sensitive deposition; pharma processing and testing; reaction control. |
Fluid baths, manifolds, liquid coils. Used as off-the-shelf additions to OEM products, cold traps, electron microscopes, process equipment and instrumentation. |
Blast or process freezers, -70°C process or storage freezers; reach-in or walk-in freezers. Used in pharma production, blood and biological repositories, archiving, life sciences, biotechnology, industrial processing and PCM conditioning. |
Controls, Monitoring and Predictive Maintenance
Farrar Intermediate servers can be configured for use with standard or custom instrumentation. Instrumentation can be specified per customer preference, custom designed by Farrar Scientific or acquired from open market sources.
All designs include strategic operational monitoring considerations as well as general performance and monitoring functions to optimize the server process management and control.
Operational Monitoring
Operational monitoring is achieved through data acquisition from thermocouples and transducers imbedded within the system during manufacture. This data includes state points or thermodynamic properties of selected refrigerants.
The combination of state point monitoring, together with real-time data logging of electrical current, ambient temperature and other key parameters, creates an accurate view of the dynamic functional relationships necessary for predictive maintenance.Predictive maintenance is managed through local or remote monitoring.
