CP-031HT Peltier-Thermoelectric Cold-Plate Cooler
• Heats as well as cools (when used with heat & cool / bipolar controller).
• The High Temperature (HT) Series can be used to heat to 100°C. Non-HT Series units
are limited to 70°C.
• Small, low-cost standard cold plate cooler.
• Provides effective, direct-contact cooling or heating.
• Powered by 12 VDC; its low power consumption makes it compatible with a wide
range of our temperature controllers.
• Threaded holes are located in the cold plate for easy attachment of a temperature
sensor, interface plates, and other cooled plates.
• Can be customized for production-sized orders to meet your exact requirements.
• 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 -20 °C or over 70 °C.

1Current, at steady-state, is rated at +25 °C ambient, +25 °C internal, maximum heat removal. At -23 °C cold plate, the typical steady-state current is 4.6 A.
2Current, at steady-state operation under-worst case conditions, is rated at -20 °C ambient, +100 °C internal, maximum heat removal.
3 Total current consumption is sum of TE current and Fan current.

Example: You need to maintain the cold plate at 10 °C while in a 25 °C ambient. The cooler can remove a maximum of
approximately 22 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.

Example: You need to maintain the cold plate at 30 °C while in a 0 °C ambient. The cooler can add up to approximately

generating heat), you would need multiple coolers or a cooler with a larger heating capacity.
