ABOUT THE TEC MODULE

Density measurements at specific temperatures are required for certain applications. The AccuPyc II
Thermo Electric Cooling (TEC) Module maintains an accurate temperature control during analysis
using the principle of Peltier cooling.
TEC Modules, also known as Peltier coolers, are solid-state heat pumps that utilize the Peltier effect
to move heat. By passing a current through the TEC Module, heat is transferred from one side of the
module to the other, typically producing a heat differential of approximately 40° C.
The transferred heat is then removed from the system through the combination of a heat sink and
fan, cooling the system to maintain a set temperature for accurate analysis.
TEC systems feature:
n fast dynamic response
n long-life
n no moving parts
n no use of refrigerants or circulated liquids / antifreeze
