■Characteristics・ The cooler produces cool air such that the maximum temperature difference
is －55℃ compared to the entered temperature by providing compressed air.
・ The cooler efficiently cools narrow holes that cannot be cooled by cool water and leaky parts and improves cycle time.
・Effective at locally cooling molded parts.
■Usage・Use the cooler with 0.3～0.7MPa of pressure.
・ Use an air dryer to provide dehumidified air and set an air filter (filtration 40µm and lower) and an oil mist separator to prevent foreign objects from getting in.
・Be careful not to burn yourself with hot air from the heat release outlet.
・ Release air that cooled a mold from the cool air jet outlet into the air.If you do not release it, cool air will stop.
・If the air is noisy, apply any silencer.
■Breakdowns and repairs・If cooling gets less effective, follow the procedure below for check.
①Readjust the temperature adjusting screw.
②Check if a clogged filter or mist separator causes reduction of pressure.
③Check if enough air consumption on the right page is provided.
・We assume no responsibility for dismantled products.
■Cool air temperature adjusting methodUse the temperature adjusting screw on the body tip to adjust cool air temperature. If you loose the temperature adjusting screw, cool air temperature drops and the amount of cool air decreases. Conversely, if you tighten the temperature adjusting screw, cool air temperature rises and the amount of cool air increases.

■Temperature・Heat amount characteristic・�The air descent temperature is the descent temperature against the air temperature at the entrance.
・�When the adjusting screw is completely tightened, the value for the number of adjusting screw rotations is 0.
・The following graph shows a characteristic of the air jet cooler only.
・ Amount of heat (W) is power that cool air from the cool air jet orifice can draw from cooling objects. 1W＝0.86kcal/h
■Example of how to mount・Screw a cooler on the side of a mold for direct flow of cool air. (Photo1)
※With AJCMV mounted
・Set a cooler near the side of a mold and use pipes and the like for flow of cool air. (Photo2)
※With AJCMH mounted
■Air jet cooler peripheral parts
■ExplanationPrinciple of cool air separationAs the following diagram shows, compressed air sent to this device is forcibly rotated at high speed in the device to separate cool air from hot air , which applies the principle of vortex theory. For this phenomenon, only cool air can be taken out.
