Applications for Vortex Tube Spot Cooling

The EXAIR Mini Cooler family is one of the many vortex tube based Spot Cooler products that EXAIR offers.  This is the smallest of the group coming in at 550 BTU/hr of cooling capacity.  The Mini Cooler Systems  are available in two options.

EXAIR’s Mini Cooler is available with a single point hose kit or a dual point hose kit.
  • The Single Point Outlet option will give you ten inches of flexible cold outlet to easily position the cold air stream near the target point.
  • The Dual Point Outlet option gives ten inches of 1/4″ flexible outlet that then splits to two separate four inch lengths of 1/4″ flexible cold outlet hoses.
  • Both include point or flat fan tips for the cold air outlets
  • Both include a manual drain filter separator
  • both include the swivel magnetic base with 100 lb. pull magnet.

The Single Point Mini Cooler with a Flat Fan Tip installed on a milling application where liquid coolant cannot be used due to material constraints.

The single point hose kit is ideal for small diameter milling or drilling applications where the cold air can cover the contact area of the cutter.  It can also be used on soldering, industrial sewing, ultrasonic welding, or even small punching applications to list just a few.

The dual point hose kit is ideal for two separate small diameter cutters, one larger diameter cutter, rotary style knives where there material is being slit, or larger diameter multi-point ultrasonic welders/punches.

When using the Mini Cooler the adjustable cold outlet stays in place and can easily bend around fixtures, spindles, welding horns, or dye aligning pins.  The swivel magnetic base gives additional adjustment at the base of the cooler to aid in the versatility of this product.   To further the adjustability of the cooler the operating pressure can easily be adjusted to lower or raise the cooling capacity of the Mini Cooler to meet the demands of the precise application.

If you believe you have an application that would benefit from the use of a Mini Cooler, or you are unsure which product would be ideal for your application please contact an Application Engineer.  we are all here, willing to help however possible to get your application improved in both safety and efficiency.

Cooling Gelatin Pills Using The Mini Cooler

I recently worked with an OEM on a cooling application for a gelatin pill forming machine they designed for their customer. In their machine design, the gelatin film leaves an extruding machine then travels between 2 punch rollers to form the pills. After the pills are formed, they are supposed to drop onto a chute feeding a conveyor to carry the pills to the bottling/packaging area.

The problem they were having was the film was retaining heat which caused the pills to occasionally stick to the roller, resulting in rejects and lost production time. They were looking for an economical way to blow cold air across the rollers and film but were concerned about putting too much demand on their customer’s compressed air system.

After reviewing the photos and discussing the details, I recommended they use our Model # 3308 Mini Cooler System with dual point hose kit. The Mini Cooler provides a 50°F temperature drop from the incoming supply air temperature and provides 550 Btu/hr. of cooling capacity. The system includes a swivel mag base for easy installation while the dual point hose kit would allow them to direct the cold air to blow across both rollers from a single device. Compressed air demand is minimal, at only 8 SCFM @ 100 PSIG, alleviating their concern for the customer’s compressed air system.

If you are having heat related issues with your process or to discuss a particular application or product, give me a call, I ‘d be happy to help.
