General Kinematics SPRAY-COOL™ water addition systems provide precise in-process sand conditioning and cooling of foundry sand. SPRAY-COOL™ improves the efficiency of fluid bed sand coolers and systems based on evaporative cooling. Combining in-process temperature and weigh sensing components and water spray nozzles, SPRAY-COOL™ systems deliver the exact amount of water needed to achieve a pre-set moisture/temperature for sand conditioning, regardless of changing flow rates and varying sand temperature.
