STREAMTEK Tool Cooling Cold Gun System:
STREAMTEK’s Tool Cooler is a new solution to a very old problem. The Cold Air Gun Systems produces a flow of clean cold air flow at approximately 50°F (28°C) below compressed air supply temperature. The unit is muffled for quiet operation. It will remove heat to prolong your tool life and increase productivity on machining operations when liquid coolants simply cannot be used. In addition, there are no moving parts to wear out.

The STREAMTEK Tool Cooler often replaces costly mist coolants and improves the output and quality of all types of drying machining operations from plastics to metals. Made of heavy-gauge stainless steel, they are precision-machined, assembled and tested under strict quality control. They will never rust or pit when exposed to water, coolants, or other corrosive materials.

Tool Cooler Cold Gun System – Operation:
STREAMTEK’s Tool Cooling System uses a simple Vortex Tube to produce cold air at one end. The hot air is exhausted as waste at the muffled hot end of the Tool Cooler. As the cold exists through the flexible adjustable hose, it’s muffled. The adjustable hose is used to direct the air where cooling is needed.

To allow for easy mounting and portability the magnetic base is used to mount the Tool Cooler to the machine.

TOOL COOLER: Specifications

Use and Selection of your Tool Cooler:

The Single Point Tool Coolers should be used where a concentrated airflow is needed such as in grinding & drilling. The Dual Point versions are typically used in applications where the heat is generated over a large surface area such as in milling, sawing, chill rolls or application of hot melt adhesives.

Controlling the Cold Air:

The STREAMTEK Tool Cooler Cold Gun System provides instant cold air! A solenoid valve (Model SLD00-1) is an excellent way to turn the compressed air supply to the Cold Gun system on-off as it is needed, which in turn conserves compressed air usage. A Manual Shutoff Valve (Model VLV014-1) can also be used to cycle on and off.

The Compressed Air Supply:

The Tool Cooler Cold Gun System is engineered to use compressed air supply of 80-100 PSIG (5.5 to 6.9 BAR). If lower input pressures are given, both temperature drop and flow will be reduced. A clean dry source of compressed air is imperative in the operation of the STREAMTEK Vortex Tube Tool Cooler.

1. What is the difference between the Regular and Advanced Tool Coolers?
The Advanced Tool Cooler has twice the cooling capacity of the Regular Tool Cooler – cabinet cooling the part in less time. Both coolers are constructed of Stainless Steel (Type 303) and are available with dual-point or single-point flexible hose kits.

2. 2. What’s the difference between the Vortex Tube and Tool Cooler?
The Tool Cooler has a fixed maximum flow capacity which cannot be adjusted. The control valve on the Vortex Tube within the Tool Cooler has been replaced with a preset orifice which allows the Vortex Tube to produce the absolute highest cooling capacity available. In addition, the STREAMTEK Tool Cooler also incorporates a cold end muffler, allows for a flexible hose kit, and includes a magnetic base for quick n’ easy mounting.

TOOL COOLER: How it Works

(A) Compressed air enters into the vortex tube component of the Tool Cooler.

(B) The vortex tube splits the compressed air into hot and cold air streams.

(C) The hot air from the vortex tubes is exhausted into the atmosphere after being muffled.

(D) The cold air stream enters the muffler and passes through the flexible hose, which directs the airflow to the point of use.

(E) A strong magnetic base provides quick n’ easy portability & mounting.
