Epoxy coated fin evaporator is the optimum anti-corrosion solution for fruit ripening coolers operating in coastal, high humidity and polluted packhouse environments. It resists corrosion caused by fruit volatile acid, condensation and salt mist, greatly extending coil lifespan. For banana & avocado ripening rooms, epoxy+hydrophilic composite coating balances anti-corrosion performance, condensate drainage and heat exchange efficiency, perfectly matching small ΔT, high RH ripening operation conditions.
