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.
Reduced energy consumption by returning existing heat energy
Less emission to the environment by absorbing pollution
Reduced condensation of oligomers in the TDO by adjusting the amount of fresh and exhaust air
Improved film quality by using preheated fresh air
- Stand alone unit for preheating fresh TDO air supply
