Have you ever wondered about the differences between the Adjustable Spot Cooler and the Cold Gun?
In their most basic form, these two items are very similar – both require a compressed air supply, both produce localized cold air flows, both have magnetic bases, and both have the same basic profile. However, under closer scrutiny, we can see that the Adjustable Spot Cooler can pivot on its magnetic base. It also has the ability to vary the cold fraction and thereby vary the cold outlet temperature and flow. The Adjustable Spot Cooler is supplied with multiple generators which allow for control of the compressed air inlet flow – yet another way to vary the cooling capacity of the Adjustable Spot Cooler.
These distinctions make the Adjustable Spot Coolers the most versatile spot cooler on the market. They can be used in many applications in which the exact cooling capacity is not known, a target temperature is required, or if the application requires temperature variations. For example, if a customer has an application where a specific temperature is required or if shrinking/expansion is critical, the Adjustable Spot Cooler can provide a solution unavailable with a Cold Gun. EXAIR offers them with either a single outlet for direct cooling or a dual outlet to capture both sides.
The Cold Gun, on the other hand, produces a preset volume at a specific temperature drop. This is great for applications with steady heat loads like machining, grinding, or laser cutting; or for applications in which you need to be free from tampering. The Cold Gun will produce consistent performance without any modification needed from the end user. EXAIR offers two types, the Cold Gun Aircoolant System and High Power Cold Gun Air Coolant System, which gives twice the cooling capacity. Both units can be purchased with a single outlet hose or a dual output hose.
There are many applications for our Spot Coolers. They help remove heat to extend tool life, and they can help eliminate coolant to improve production rates. If you have an application where you need to remove heat and do not know which unit to select, an Application Engineer at EXAIR is here to help you.
