AIR JET COOLERS FOR MOLD –COMPACT TYPE–
■ 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. 1 W = 0.86 kcal/h

■ Explanation Principle of cool air separation
■ Example of how to mount • With AJCMV mounted ... Screw a cooler on the side of a mold for direct flow of cool air. (Photo 1) • With AJCMH mounted ... Set a cooler near the side of a mold and use pipes and the like for flow of cool air. (Photo 2)

As 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.

■ Cool air temperature adjusting method
■ Characteristics • The cooler produces cool air such that the maximum temperature difference is –67°C compared (No.150 is –55°C) to the entered temperature by providing compressed air. • The cooler efficiently cools narrow holes that cannot be cooled by cool water
Example
Use the temperature adjusting screw on the body tip to adjust cool air temperature. Loosen: Cool air temperature drops, and the amount of cold air is reduced. Tighten: Cool air temperature rises, and the amount of cold air increases.

• Use an air dryer to provide dehumidified air and set an air filter (filtration 40 μm and lower) and an oil mist separator to prevent foreign objects from getting in. • 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.) • Be careful not to burn yourself with hot air from the heat release outlet.

■ Breakdowns and repairs • If cooling gets less effective, follow the procedure below for check. ① Readjust the temperature adjusting screw. ② C heck if a clogged filter or mist separator causes reduction of pressure. ③ Check if enough air consumption on the right page is provided. • We assume no responsibility for dismantled products.
