D.T.S., Halle Germany
The D.T.S. is a company that deals with the technical using of the properties of thin thermoelectric films. Its staff has a long experience in the field of thermoelectric materials and devices. After intensive research they succeded in developing a thin film thermoelectric generator which converts thermal energy in electrical energy directly and whose output is compatible to the requirements of recent micro electronic and micro matched system loads. With these Low Power Thermo Generators (LPTG) users at the first time have at their disposal new, self-sufficient, harmless to the environment energy sources for the electrical small performance range. We also develop a LPTG for you, whose thermal and electrical design corresponds to your special demands. With the help of up-to-date high vacuum deposition equipments, thin thermoelectric films are prepared and many different deposition tasks are solved.
Manufactures low power (10-40uW) thin film thermoelectric power generators.

Hi-Z Technology, San Diego CA
Thermoelectric generators with combustion heat sources are being developed for the U. S. Army, TACOM-ARDEC, by Hi-Z Technology, Inc., for battery replacement in the field and for powering lightweight portable battery chargers. These small generators range in output power from 0.3 watts to 20 watts. The main thrust of the development work is to demonstrate utilization of diesel or other military logistics fuel as the heat source. The thermoelectric generating modules being used operate at relatively low hot side temperatures and with modest power conversion efficiencies. Nevertheless, the concept shows potential advantage over batteries in watts per pound and watt-hours per pound, thus addressing the "battery problem" and the need for lightening the soldier's battery burden, and doing so at reasonable costs. The thermoelectric material used in this application is current state-of-the-art. However, Hi-Z is also developing advanced thermoelectric materials and devices that promise significantly improved performance in the near future. Manufactures thermoelectric power generator modules.

Hui Mau Cooling Equipment, Bejing P.R.China
Thermoelectric technology is an active thermal management technique based on the Peltier effect. It was discovered by J.C.A Peltier in 1834, this phenomenon involves the heating or cooling of the junction of two thermoelectric materials(bismuth and telluride) by passing current through the junction. During operation, direct current flows through the TEC module causing heat to be transfered from one side to the other. Creating a cold and hot side. If the direction of the current is reversed, the cold and hot sides are changed. Its cooling power also can be adjusted by changing its operating current. A typical single stage cooler (Figure. 1) consists of two ceramic plates with p and n-type semiconductor material (bismuth ,telluride) between the ceramic plates. The elements of semiconductor material are connected electrically in series and thermally in parallel. Manufactures power generating and cooling modules.

Taihuaxing Trading/Thermonamic Electronics, Xiamen P.R. of China
The power module is designed and manufactured by our unique technology for converting heat source directly into electricity. The module is Bi-Te based thermoelectric module that can work at the temperature of as high as 260°C(500F) continuously and intermittently up to 380C(680F) heat source without degrading. The thermoelectric module will generate DC electricity as long as there is a temperature difference across the module. The more electricity will be generated when the temperature difference across the module increases, and the efficiency of converting heat energy into electricity will increase too.Our unique technology also ensures the modules can stand with cycling in large temperature range without degrading. Our modules can be in single ceramic plate and double ceramic plate pattern per client's request. We also provide ceramic plates as partition in thermally conductive and electrically non conductive.Currently, we have 126 couples in size of 40mmx40mm, 35mmx35mm and 56mmx56mm series modules as below for different applications. We also can make it in size of 30mmx30mm. Manufacturer of thermoelectric cooling and power generating modules.
