CP-040HT Peltier-Thermoelectric Cold-Plate Cooler
• Heats as well as cools (when used with heat & cool / bipolar controller).
• Provides effective, direct-contact cooling for small heat loads at low temperatures.
• Can also be used for heating up to 100 °C.
• Highly efficient 67 mm wide heat sink for compact size and low power consumption.
• Airflow can be blocked at one end of the heat sink, which provides more options for
routing air flow within instruments.
• Compatible with a wide range of temperature controllers.
• Threaded holes are located in the cold plate for easy attachment of a temperature
sensor, interface plates, and other cooled plates.
• An optional bracket is available for converting the cooler into a bench-top version.
• CE marked, RoHS compliant.

Performance is based on unrestricted air flow to fans
and from air-flow outlets. Do not operate if the heat sink
or cold plate exceeds 100 °C. Do not operate fans at air
temperatures below -10 °C or over 70 °C.

Example: You need to maintain the cold plate at 0 °C while in a 25 °C ambient. The cooler can remove a maximum of
approximately 20 W of heat from the cold plate. If the heat gain from the ambient plus anything else actively generating
heat exceeds this, you would need a cooler with a larger cooling capacity or multiple coolers.
