Peltier effect

Thermoelectric coolers from Rittal employ the Peltier Effect to provide 100W of cooling output without refrigerants or gases and with very few moving parts. This is achieved by passing an electric charge through two dissimilar conductors which, as discovered by 19th Century physicist Jean-Charles Peltier, lowers the temperature of the Peltier element.

Fans are then used to circulate the cool air.

Small in size (400mm H x 125mm W x 155mm D), and weighing just 3kg, Rittal's versatile thermoelectric coolers can be mounted internally or externally, horizontally or vertically and produce very little noise or vibration.
