Fighting Physics for 112 Years: Why Your Evaporator Design Is Backwards (And Why Nobody’s Questioning It)
Your roof-mounted evaporator sits in warm air but pulls from below it, ignoring the heat surrounding the unit. This 112-year-old design flaw costs you many Rands annually in wasted fuel. Small truck refrigeration manufacturers know bottom-intake evaporators fight basic physics – warm air rises to the ceiling where your unit is mounted, yet the intake faces downward pulling cooler air from below. Why hasn’t anyone questioned this?
