Why heat pump dryer?

The new heat pump technology used in the drying industry is a major breakthrough, which saves the operation cost up to 75%. The difference similar as the traditional electric water heater and the heat pump water heater, because heat pump is to transfer the heat in the air from outside to the chamber inside.

Bellowing is the electricity consumption in different dryers:
