Turn waste heat into savings and sustainability

In nonwovens production, dryers are among the most energy-intensive processes, often releasing valuable heat into the atmosphere.

With the ANDRITZ Heat Recovery System (HRS), this untapped energy can be captured and reused, turning energy loss into measurable savings while supporting your sustainability goals.

How it works

The ANDRITZ Heat Recovery System captures hot exhaust air from the dryer and transfers its energy to incoming fresh air via a high-efficiency air-to-air heat exchanger.

By pre-heating the make-up air before it enters the dryer, the system significantly reduces the energy required for heating—resulting in improved overall process efficiency.
