Refrigerated Cooling Systems (RCS90 and RCS40)

The RCS is frequently selected as the preferred cooling device by thermal analysts for trouble-free, unattended DSC and MDSC® operation over a broad temperature range. Because it is a sealed system requiring only electrical power, the RCS has advantages for operation in areas where other refrigerants are difficult or expensive to obtain. TA Instruments offers two complementary models: the RCS90 and the RCS40. Both use the same cooling head, which fits snugly over the Q Series™ DSC Cell and completely eliminates frosting issues typical in competitive designs. Both controlled and ballistic cooling is achievable.
RCS90 The RCS90 employs a two-stage refrigeration system, which permits convenient DSC/MDSC operation over the temperature range from -90 to 550¡ãC. Typical RCS90 controlled cooling rates are detailed in the table below. Ballistic cooling from 500¡ãC to ambient is achieved in about 7 minutes. The RCS90 is compatible with all ambient pressure Q Series™ DSC Systems.
RCS40 The RCS40 employs a single-stage refrigeration system, which permits convenient DSC and MDSC® operation over the temperature range from -40¡ãC to 400¡ãC.  Typical RCS40 controlled cooling rates are detailed in the table below. Ballistic cooling from 400¡ãC to ambient is achieved in about 7 minutes. The RCS40 is compatible with all ambient pressure Q Series™ DSC Systems.
RCS90 Controlled Cooling Rates, from 550¡ãC (upper limit)* Controlled Rate To Lower Temperature 100¡ãC/min 300¡ãC 50¡ãC/min 120¡ãC 20¡ãC/min -20¡ãC 10¡ãC/min -50¡ãC 5¡ãC/min -75¡ãC 2¡ãC/min -90¡ãC
