￼Snow River™ Refrigeration System (-96C and -50C) A direct expansion refrigeration system with a programmable temperature range from ambient to -96C that is capable of being fully integrated to supply stable, precise and reliable cooling.
The Snow River™ Refrigeration System provides reliable, stable and cost effective cooling down to ultra low temperatures. This system can be configured to incorporate any thermal load including those offered by Abbess such as a thermal plate, ￼finned heat exchanger or a cold trap. These systems eliminate the high running cost of liquid nitrogen(LN2) systems by efficiently reaching temperatures as low as -96C. Snow River™
Refrigeration Systems can be used for:
- Thermal Vacuum Chambers
- Environmental Test Chambers (with altitude, temperature, and humidity control)
- Ultra-low Temperature Freezers
- Lyophilizers (freeze dryers)
- Lasers, NMRs, Liquid chromatography, Mass Spectrometry, Cold Traps, and other devices
- Cryogenic Storage
- Biological Storage (bio refrigeration)
- DNA Storage (sample preservation)
- Forensic Samples
- Genetic Sample Storage (animal, plant, archaeological)
- Cold Traps
- Satellite Testing (space simulation)
Integration of your process or thermal load with Snow River™ is easy!
The Abbess Instruments Snow River™ Refrigeration System consists of two refrigeration compressor loops working together to cool an evaporator to temperatures as low as -96C. These evaporators can be customer supplied or custom built by Abbess to meet your specific needs. Abbess’s most common application is using a heat exchanger at the evaporator to cool a sealed bath of heat exchange fluid which can then be easily piped to the application’s heat load such as:
- Thermal plates
- ￼Thermal shrouds
- Cold fingers
- Cold Traps
- Storage Coolers
- Storage Cabinets Require a system capable of heating and coolings?

Our Snow River™ Refrigeration Systems are capable of -96C!
These refrigerators can be used in conjunction with our vacuum systems to provide space simulation profiles or they can be customized to provide cooling for a variety of other applications such as medical storage and freeze drying. These systems are entirely customizable and can be sized to cool your product, environment or working fluid at various rates. Our systems have been proven to be reliable and low maintenance in simulation systems produced for NASA and other prominent aerospace industry leaders for years and have earned a reputation for quality, performance and, control that is simply unmatched by any of our competitors. Abbess also provides support both on-site and off-site for all of our refrigeration systems.
Refrigeration Systems that come in a variety of sizes and configurations to fit your application!
Refrigeration and vacuum systems can also be custom configured in sizes ranging from 2544 BTUs/hr to 86511 BTUs/hr systems and can be designed to operate at low (-50C) and ultra-low (-96C) temperatures. These systems can be used in conjunction with our vacuum systems to provide space simulation profiles or they can be custom-made to provide cooling for a variety of other applications such as biological/medical storage and freeze drying. These systems are entirely customizable and can be sized to cool your product, environment or working fluid to specific temperatures at various rates.
Flexible Control and Diagnostic Capabilities
Abbess offers a variety of control diagnostic and test data packages that can fit your specific application and budget. These control systems could be as basic as a simple thermostatic control or as advanced as a data logging touch screen PC interface capable of integrated system diagnostics and test data, and networking of multiple chillers to handle large or variable loads. Stand-alone PID Temperature controllers can also be utilized for simple, precise thermal control and profiling.
Touch Screen PC Control Option
Touch screen PC control provides total and complete control and monitoring capabilities of your refrigeration system. The PC interface allows for data logging of system temperatures and pressures as well as full remote control of PID temperature loops. The interface is capable of providing self-diagnostic information to the user.
