Heat Recovery System (HRS)
For the Transverse Direction Orienter (TDO)
One of the most efficient ways of saving energy and money in the film stretching process is to focus on the biggest energy consumer within the system: the transverse direction orientation (TDO) unit. Heat recovery on the TDO unit leads to tremendous energy savings by recycling the heat of the exhaust air through a heat exchanger and preheating the fresh air required.
Not only does this efficient way of using rejected heat save energy; due to the preheated fresh air less condensate is accumulated in the TDO unit, which leads to a higher film quality and to less maintenance.
