Thermoelectric conditioner – Thermoelectric indoor assembly TА-АА-250-AC

Thermal management is one of the fastest growing segments of the world economy. Expert estimation makes 7.91% of the average annual growth in the period from 2017 year to 2022 year. In absolute terms, the annual market volume in 2022 year will reach 14.22 billion USD from 8.99 billion USD in 2016 year.

A large amount of energy consumed by electrical and electronic systems is converted into heat. Miniaturization of electronic devices, denser packaging of components increases heat flux densities.

The barest necessity for intensive heat removal from a limited volume is the basis for the operation of electronic equipment in a regular, trouble-free mode.

The innovative method of heat removal is based on the use of solid-state, semiconductor heat pumps - Peltier.

Crystal. Ltd more than 20 years develops and mass produces Peltier modules and many design of thermoelectric coolers based on them. 

Our mission is to provide continuous development of research, mass production and advancement of competitive products for the purposes of:

-   Strengthen the reputation as a reliable and responsible supplier

-   Improve the well-being of every employee of our company

-   Achieve the greatest profit through maximum satisfaction of customers’ requirements

-   Protect the environment

-   Promote volunteer activity 

Big experience of thermal management based on thermoelectricity, and constant study of innovations in related fields impel the company's engineering team to offer modern, reliable, compact heat elimination systems. The main goal of the research is the development, production, advancement and technical support of innovative thermoelectric coolers. The function of thermal stabilization or cooling below ambient temperature in such devices should be combined with ease of installation, connection to an accessible power source and user-friendly control and monitoring. The sample of development of innovative thermoelectric cooler is a new packaged air-conditioner TA-AA-250-AC.
