Technical details of the plate exchanger

Inspection, hygiene, and sustainability. BOIXAC recoverers are designed under strict criteria of environmental sustainability, operational efficiency, and ease of maintenance. The design facilitates inspection, cleaning, and hygiene operations, reducing downtime and extending equipment life.

Fully custom design. Especially suitable for crossflows of air, process gases, and extraction fumes, BOIXAC recoverers renew air while maximizing existing energy. Each unit is custom-designed, adapting to real process conditions and available space.

Optimized thermal relief. The interior plates incorporate an optimized smooth relief, developed to maximize the heat exchange coefficient with minimal pressure drop. This balance is key to reducing fan electricity consumption and improving overall system efficiency.
