THT New Cool - 100% electric reefer trailer

Twan Heetkamp

In 2007 we had the idea of replacing the diesel reefer unit on a trailer with a full electric one of which the energy is mainly obtained by recuperating brake energy.


The New Cool trailer is a reefer trailer that takes his energy from a special axle and from the grid. When the reefer slows down, the special Valx axle generates energy. The more the reefer slows down, the more energy is generated. The energy is stored in a custom made battery pack of 17,7 kWh. The Carrier Vector cooling engine takes his energy from the battery pack to cool the goods in the reefer. Our mission is to have a company that enables transport companies to transport refrigerated goods without pollution, without exhaust of carbon dioxide and with way less noise.
