Andritz has launched its latest innovation to reduce energy consumption in tissue drying – the PrimeDry HotAir Box.
The supplier said the system enables tissue producers to “reduce energy consumption and CO2 emissions while increasing machine efficiency.”
It said: “The PrimeDry HotAir Box recovers a portion of the exhaust air from the drying hood for reuse in the process.
“The exhaust air is separated after the air-to-air heat exchanger, filtered, and evenly blown onto the tissue web ahead of the suction roll.
“The temperature increase reduces the water viscosity of the web, resulting in higher dryness after the press.”
This means it contributes to “a significant reduction” in the total energy required to achieve the final paper dryness or to a significant increase in production, according to the supplier.
It is compatible with any suction press configuration, and the system is also suitable for new installations and rebuilds.
