-96C Cascade Refrigeration System

Abbess has the expertise in designing and manufacturing ultra-low temperature refrigeration units to fit a wide range of needs in science and industry. Abbess’s Cascade Refrigeration Systems are the most powerful closed loop cooling systems that Abbess offers. These systems eliminate the high running cost of liquid nitrogen(LN2) systems by efficiently reaching temperatures as low as -96C. This Cascade Refrigeration System can be configured to incorporate any thermal load including those offered by Abbess such as a thermal plate, finned heat exchanger … Read More

Snow River™ Cascade Thermal System (-96C to +150C)

Abbess’s Snow River™ Cascade Thermal System is a liquid circulating chiller that is capable of being fully integrated so that is supplies stable, precise and reliable temperatures in the range of -96C to +150C to any heat exchanger or thermal load. The Snow River™ Cascade Thermal System is the most flexible closed loop cooling system offered by Abbess. This system utilizes both high and low stage compressors that work together to achieve the desired temperature with higher efficiency than a … Read More

Vacuum Cold Trap, -80°C Using Cascade Refrigeration System

A Vacuum Cold Trap precipitates materials to ensure purity and reduce contamination in your process. The Abbess Instruments Vacuum Cold Trap is designed to precipitate vapors like water and other perceptible materials from gas streams developed in a vacuum processing or drying operation. Products or articles under vacuum may evolve vapors that can compromise the product or vacuum system components. The Cold Trap is used to filter the exiting gases of water, alcohol or other perceptible materials, in order to … Read More

Performance Specifications

All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:

The Vacuum Chamber is empty.
The Vacuum Chamber and other system components are clean and dry.
The System is being operated at Sea Level
The ambient temperature is 18°C +/- 2°C
All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
The specifications are not impacted by the properties of your product.

If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.

It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.
