Frequently Asked Questions

What is a thermoelectric cooling (TEC) module?

A TEC module, also known as a Peltier cooler, uses the Peltier effect to transfer heat from one side of the device to the other when an electric current is applied, enabling solid-state cooling without moving parts or refrigerants.

Can Huimao provide custom TEC modules?

Yes, Huimao specializes in customized thermoelectric cooling modules and complete units. We offer full OEM/ODM services including design, prototyping, and mass production based on your specifications.

What industries use Huimao's TEC modules?

Our modules are used in telecommunications, medical equipment, industrial automation, automotive systems, consumer electronics, aerospace, and scientific instrumentation.

Do you offer multi-stage cooling modules?

Yes, we manufacture multi-stage thermoelectric cooling modules capable of achieving temperature differences beyond -80°C, ideal for cryogenic and high-precision applications.

What is the operating voltage of your TEC modules?

Standard modules operate at various DC voltages (1.5V to 15V), but custom voltages are available upon request. We also design modules for 12V and 24V systems commonly used in automotive and industrial applications.
