The Valence Lamiflow extracts heat from the exhaust of coating, laminating, and printing machines and utilizes it to pre-warm inlet fresh air. Partial recirculation of hot air on these machines may be a better option. However, for reasons of safety, recirculation is recommended on solvent-based machines only with LEL sensors. The Valence Lamiflow conserves energy and provides operational savings with attractive payback.


LAMIFLOW Heat Recovery System

LAMIFLOW Heat Recovery System

(Flat-plate, air-to-air heat exchanger)

Processes in the flexible packaging industry use a considerable amount of heat. Optimising this heat energy by recovering waste heat can reduce costs and thus significantly increase a convertor’s bottom line and hence an attractive investment option. 

The Lamiflow is a flat plate air-to-air heat exchanger where two air streams (exhaust and fresh air) cross each other, without coming in contact. The heat exchanger comprises multiple, thin, slightly separated plates with large surface areas that allows air flow passage for effective heat transfer, with minimal pressure drop.

The sensible energy from warm exhaust air is transferred to the relatively cooler inlet air, without any mixing of the two air streams. This enables savings in energy spent to heat up fresh air from ambient temperature to the required temperature.
