The newly developed V-SHAPE Compact is available as fluid cool- er, condenser and gas cooler and offers maximum capacity on a small footprint already when oper- ated in dry mode. The HydroPad humidification pad for adiabatic pre-cooling allows for operating refrigerating plants more effi cient- ly, thereby saving money – no water treatment, no intense main- tenance works and no wetting of the coil
