Rapid heating and cooling
rates down to -25° C and a range to -35° C.
Single Stage MRTP systems heat and cool a thermal platform very efficiently. They
have rapid heating with good cooling rates down to about -20° or -25° C. They will
cool down below -35° C but the rate of change decreases rapidly below -20° or -25°
C. This is because a single stage system uses a single compressor and a single
type of refrigerant. The refrigerant used has a boiling point near -40° C. Once the
temperature differential between the thermal platform and refrigerant is less than 10° C then thermal transfer is slower and the platform cools much less rapidly.
Rapid heating and cooling
rates down to -55° C and a range to -65° C.
Cascade MRTP systems heat and cool a thermal platform very efficiently. They have
rapid heating with good cooling rates down to about -50° or -55° C. They will cool
down below -65° C but the rate of change decreases rapidly below -50° or -55°
C. This is because the refrigerant used has a boiling point near -70° C. Once
the temperature differential between the thermal platform and refrigerant falls below 10°
C, then thermal transfer is slower and the platform cools much less rapidly. A
cascade system uses two compressors and two different types of refrigerant. This allows it
to economically and reliably reach temperatures that are much lower than a single stage
system is able to achieve.
