Since 1968, Jean Claude Comby ACFRI company's founder, has developed a Blast Chilling and Deep Freezing range of cells using the vertical-type evaporator technology. This technology offers multiple benefits : Vertical homogeneity of gas repartition via a multi-layers principle Reduced bended and welded piping (reduce potential gas leaks) Vertical air flow management trough lateral air blows Pivoting Ventilation ramp for a true easy cleaning of the fan's back side as well as the 3 evaporators sides. Ultra short evaporator defrost and drying time trough an un interrupted ventilation’s air flow principle.
