Stand-alone Quench Cooler with thermal enclosure.
NOTE
: The Quench Cooler cannot be used to perform a Tzero calibration of the DSC. Therefore, only T1
heat flow is available when using the Quench Cooler.
NOTE
: The Quench Cooler requires the manual silver lid provided in the Discovery DSC™ kit, and
therefore cannot be used with the Autosampler. The DSC Autosampler is disabled during Quench Cooler
operation.
Refrigerated Cooling System (RCS)
The Refrigerated Cooling Systems (RCS) are used to perform DSC cooling experiments. There are three
different models offered by TA Instruments: the new RCS120, the RCS90, and the RCS40. All three mod-
els have a cooling head, which is made up of an internal heat exchanger, anti-condensate heaters, and vari-
ous other components. The cooling head fits over the DSC cell.
•
The RCS120 is a three stage, vapor compression refrigeration system with an attached cooling head.
The operating range of the RCS120 is -120 to 400°C.
•
The RCS90 consists of a two-stage, cascade, vapor compression refrigeration system with an attached
cooling head. The RCS90 can be used for experiments requiring cooling within an operating range of
–90 to 550°C. The maximum rate of cooling depends on the temperature range of your experiment.
•
The RCS40 consists of a single-stage vapor compression refrigeration system with an attached cooling
head. The RCS40 can be used for experiments requiring cooling within an operating range of –40°C to
400°C. The maximum rate of cooling depends on the temperature range of your experiment.
CAUTION: We recommend that you do not use the RCS40 when running long isothermal experi-
ments above 325°C. Damage to the unit can occur if used at high temperatures for extended
periods. Contact TA Instruments for more information.
MISE EN GARDE: Nous recommandons de ne pas utiliser le RCS40 lorsque vous effectuez de
longues expériences isothermes au-dessus de 325°C. L'appareil peut subir des dégâts s'il est utilisé à
des températures élevées sur de longues périodes. Contactez TA Instruments pour plus de renseigne-
ments.
