Need to Cool Tooling but Limited On Compressed Air? Consider the Mini Cooler

I recently had a chat conversation with a customer who was looking to cool the tooling on his CNC router, mill and lathe in his small machine shop. During the machining process, as the tooling would begin to heat up, it would warp the bit, causing irregularities in the finished product. In some cases the tooling was getting so hot, it would actually break, creating a safety concern.

He had reviewed some of our cooling products and was thinking of using our Cold Gun in the application but was concerned with the air demand. The Cold Gun consumes 15 SCFM @ 100 PSIG and provides a 50°F temperature drop (from supply temperature) with 1,000 Btu/hr. of cooling capacity. The problem was that his compressor only produces a little over 9 SCFM. I explained that the existing compressor would in fact be undersized as it doesn’t produce enough volume to keep up with the demand of the Cold Gun.

Model 3808 Mini Cooler System with Single Point Hose Kit, includes swivel magnetic base and filter separator to remove moisture and particulate from the air supply.

Due to the limited amount of compressed air available, our Mini Cooler System, Model # 3808, would be the better solution. The Mini Cooler also provides a 50°F temperature drop with a little less cooling power, 550 Btu/hr., but this system only requires 8 SCFM @ 100 PSIG, falling within the existing compressor’s output capacity. The Mini Cooler also includes a magnetic base as well as flexible tubing to direct the cold air to the desired location, making it easy to move from machine to machine.

The Mini Cooler is the ideal solution for small tool or part cooling, with minimal air consumption.

The Adjustable Spot Cooler Is Ideal For Small Parts Cooling

I recently worked with a customer who was trying to cool some small part housings after they leave a wash system. The parts are currently placed in a wash tray where they travel down a conveyor belt and into the washer where they are heated to around 160°F. As the parts exit the washer, the belt is stopped so the parts can be left to cool before an operator places the parts into their dryer system. This cooling process was taking about 15 minutes before the operator was able to safely handle the parts. This cooling delay was negatively affecting their production cycle. They were looking to eliminate the 15 minute cooling cycle by incorporating some type of air cooling system so the parts could be quickly processed to the dryer. They wanted to standardize on a single device as they manufacturer a variety of part shapes with the largest being a valve housing that measures close to 2″ x 2″.

The customer was able to send a few photos of their parts and after reviewing the information sent, I recommended they use our Model # 3925 Adjustable Spot Cooler System with dual point hose kit. Incorporating a Vortex Tube, the Adjustable Spot Cooler is able to produce cold air temperature as low as -30°F, based on ambient supply temperature. The unit features a temperature control valve that allows for simple adjustments of the temperature of the exhausting cold air as well as the volume of air being discharged.  The system includes 2 additional generators which provide more or less airflow volume through the device as well as cooling capacity (Btu/hr.) for even  more control. The dual hose kit separates the cold air into two separate airstreams to provide for a wider coverage area or in this particular case, the customer would be able to treat both sides of the housing for even cooling. The magnetic base makes for easy installation without having to make expensive modifications to their existing setup.
