Safety and Heat Recovery

In the printing and converting processes, the release of solvent laden air directly into the atmosphere can have environmental and health implications.

Heat recovery units and LEL (lower explosive limit) monitoring systems are becoming the norm to ensure safety, compliance and savings. Heat usage is optimised by the use of recirculation through LEL sensors and/or air-to-air heat exchangers. The extracted air is then used effectively and optimised when taken to an RTO or solvent recovery system.

The NIRA Neptune is a lab based residual solvent analyser that uses gas chromatography to quickly analyse the residual solvents in single or multilayer films.
