OSTRO W

V-type double-row dry cooler

OSTRO W is a product range of V-type double-row dry cooler designed to meet the needs of high capacity exchange in dry cooler and condenser operation for the industrial process, HVAC air conditioning and refrigeration. With the PAD or SPRAY versions the capacity increases, thanks to water injection, are very significant and guarantee a legionella-free solution.
