Successful start-up of Ircon-Solaronics gas infrared UniDryer® systems on a board machine of one of the largest paper & board manufacturing groups in China.

It is a repeat order from this customer following a previous successful installation done in 2023.  For this board machine, Ircon-Solaronics supplied three gas Unidryer systems to replace existing electrical IR dryers installed on three coating stations of the 5,6 meters width board machine.

In September 2025, our service engineers have successfully started up the gas infrared dryers.
The non- contact dryer solution included three UniDryer® systems equipped with 4 rows of last technology high power and efficiency GEM12-Hi infrared emitters. To further optimize the overall energy efficiency, Ircon-Solaronics supplied an Energy Recovery System (ERS) between the gas infrared UniDryer® and the existing steam heated air dryers. The ERS principle of Ircon-Solaronics ERS solution consists of using a major part of the hot exhaust air from the UniDryer® hoods as make-up air for the air-dryers. This significantly reduces the energy consumption of the Air Dryers and thereby the energy economy of the total drying is improved as well.
