kylsprayer

A kylsprayer, or cooling sprayer, is a device that applies a fine spray of coolant to a surface or part to reduce its temperature rapidly. It is commonly used in metalworking and other manufacturing processes where local heating occurs during cutting, grinding, or forming. The system typically comprises a reservoir, a pump, a nozzle, and a control mechanism to regulate flow and spray pattern. Coolants are often water-based or glycol-based, sometimes with additives to improve lubrication or chip evacuation. Many setups recirculate coolant through filtration to reduce waste and maintain fluid quality.

Operation involves pressurized liquid being released through a nozzle. Nozzle design determines droplet size and spray geometry, ranging from atomized mists to solid jets. The cooling effect arises mainly from evaporation and, in some cases, direct liquid contact with the surface.

Applications and benefits include managing tool temperature, enabling higher cutting speeds, improving surface finish, and extending tool life. Cooling sprays also aid in debris removal and temperature control of components sensitive to heat.

Safety and environmental considerations emphasize using appropriate coolant chemistries, guarding against skin or eye exposure, and ensuring adequate ventilation. Proper containment and drainage are necessary to prevent environmental contamination; regular filtration and maintenance help prevent nozzle clogging and bacterial growth.
