EVAPCO's patented Thermal-Pak coils feature a unique elliptical tube design which provides maximum heat transfer and thermal performance with minimum pressure drop. The elliptical tube design allows for closer tube spacing pitch translating into greater coil surface area per plan area than round tube coils. In addition, the Thermal-Pak design has lower resistance to airflow and also permits greater water loading, making the Thermal-Pak coil the most effective design available. Thermal-Pak coils are available in galvanized steel and stainless steel with or without casing. Mr. GoodTower Australia can design and manufacture replacement coils for all makes and models of evaporative cooling equipment.
