ULVAC-RIKO to Sell Thermoelectric Conversion Efficiency Evaluation System for Small Modules Mini-PEM

Yokohama, Japan, July 3, 2014 - (ACN Newswire) - ULVAC-RIKO, Inc. (Head office: Yokohama, Kanagawa, Japan; President and CEO: Narishi Gonohe; hereafter referred to as ULVAC-RIKO) has developed the evaluation system for thermoelectric modules which can generate power using waste heat or unutilized thermal energy and is going to sell it as "Thermoelectric Conversion Efficiency Evaluation System for Small Modules Mini-PEM" from July.

Heat recovery technology has received a lot of attention in recent years. The technology takes advantage of thermal energies ejected from many situations such as an incinerator and automobile engine room, etc. and recovers them as regenerated energies. Among the technologies, the generator technology in thermoelectric materials does not have drive sections when converting thermal energies into electricity, which therefore leads to growing demand for such technology as maintenance-free and clean technology.

ULVAC-RIKO, Inc. has been selling the material evaluation system in thermoelectric generation development. The Mini-PEM makes materials small-modularized, gives temperature difference to the module, and then recovers maximum power generation amount and heat flow. Using a result of the evaluation, the system is also capable of calculating and evaluating the conversion efficiency.

The system can evaluate small modules with 10 mm x 10 mm or less, module with a pair of thermoelectric materials and thermoelectric material alone. Due to this, it can do a performance evaluation with small modules during development process from material evaluation to practical use before considering making a thermoelectric module, which will be actually used. Accordingly we think it can evaluate not only modules but joint technology as well.


- Capable of evaluating maximum power generation amount and heat flow when giving temperature difference to small modules.
- Capable of evaluating the conversion efficiency from power generation amount and heat flow at each temperature spot.
- Capable of evaluating with small samples such as a pair module and thermoelectric material alone.
- With a heater embedded, temperature variable up to 500 deg C on high temperature side.
- Cooling by cooling water flow on low temperature side.
- Capable of evaluating a module with up to 10 mm x 10 mm.
