Application Tips
1. Never heat TE module more than 200˚C (TEC
assembled at 230˚C).
2. Never use TE module without attached heat sink
at hot (bottom) side.
3. Connect TE module to DC power supply
according to polarity.
4. Do not apply DC current higher than Imax.
Installation
1. Mechanical Mounting. TEC is placed between two heat exchangers . This construction is fixed by screws or
in another mechanical way. It is suitable for large modules (with dimensions 30x30mm and larger). Miniature
types require other assembling methods in most cases.
2. Soldering. This method is suitable for a TE module with metallized outside surfaces. RMT provides this
option and also makes pre-tinning for TE modules.
3. Glueing. It is an up-to-date method that is used by many customers due to availability of glues with good
thermoconductive properties. A glue is usually based on some epoxy compound filled with some
thermoconductive material such as graphite or diamond powders, silver, SiN and others. The application of
a specific type depends on application features and the type of a TE module.
