The scale of Yazaki's Fayoum factory meant the distance between central plant equipment and the furthest production zones exceeded single-circuit piping limitations. Rather than force one oversized loop to cover the whole footprint, ERATEC split the load across independent, modular VRF circuits per floor and zone.










The re-zoned circuit design ensured balanced refrigerant distribution and peak operational efficiency, guaranteeing the required 240 TR of cooling output across all administrative and production areas.
