Our distributor in Peru recently contacted me with an application they were working on with a customer of theirs that deals in the mining industry. They are one of the largest gold mining companies in South America and were looking for a means of keeping their saw blades cool without having to use any type of coolant or water.
In this specific application, they had been using water to maintain the temperature of the blade while cutting. While this did work, it created quite a mess and also resulted in product contamination. The water on the floor presented a slipping hazard and production would have to periodically be halted so that someone could come by and clean the mess off of the floor. So, not only were they creating a contamination issue, but also a safety concern as well as lost production time.
Our distributor introduced them to EXAIR and our line of Cold Gun Spot Cooling Products. By replacing the water cooling with (2) Model 5230 Cold Gun systems, they were able to maintain the temperature of the blade at 24°C (75°F), well within their specifications. This allowed them to completely eliminate the need for water as a cooling method, improving their worker safety as well as increasing production.
EXAIR’s Cold Gun utilizes Vortex Tube technology to create two streams of air: one hot and one cold. The hot air is muffled and exhausted, while the cold air is also muffled and ducted to deliver a cold stream of air directly onto the material needing to be cooled. With only a supply of clean, dry compressed air required to operate, installation is quick and easy. Since the Cold Gun has no moving parts to wear out, there’s also no maintenance required so long as the Auto-Drain filter included in the kit is installed upstream of the Cold Gun.
If you’re tired of dealing with messy water-based cooling systems or equally messy coolants, give an Application Engineer a call today and try out a Cold Gun. With our Unconditional 30 Day Guarantee, there’s absolutely no risk to do so!
