Contiweb partnered with the STF Imprimeries Group in France to upgrade seven heat-set web offset production lines with the newly launched Single Burner Operation dryer enhancement, achieving up to a 33% reduction in gas consumption during production and up to a 50% reduction in standby mode.
The upgrades will be implemented on Contiweb hot air dryers at STF Imprimeries Group’s facilities, including BLG in Toul, IPS in Pacy, IPS in Reyrieux, and France Offset Tipo Rotatives in Pusignan. These upgrades are part of a broader package and are further supported by substantial financial subsidies from French energy suppliers (CEE certificates) designed to promote environmentally conscious business practices.
Contiweb dryers are known for their drying capabilities, but many modern print jobs no longer require maximum drying output. Recognizing this, STF Imprimeries Group opted for Contiweb’s Single Burner Operation enhancement, which allows the deactivation of the upper burner chamber. By using hot air from the lower chamber to dry both sides of the paper, this enhancement delivers top-quality results while reducing gas consumption by up to 50% for applicable jobs. The upper burner chamber can be easily reactivated via the HMI panel on the dryer.
