How Exair Cold Gun Cools Brazed Plate!

Brazing is a process that joins two or more metal surfaces by letting molten metal flow into the joint. The filler metal has a lower melting temperature than the parts to be joined to keep the workpieces from melting
 Although brazing is one of the oldest joining methods, it is still used today for a good reason.

Once Our Principal Exair-USA  provides a cooling solution to a manufacturer of custom hose and tube assemblies is brazing a 6" diameter metal plate. This joint causes the plate to heat up and prevents the plate from being comfortably picked up by an operator. They are looking to speed up production rates by cooling the plate faster, allowing the operator to pick up the plate and move it to the next step of manufacturing. 

They have chosen an EXAIR Model 5330 High Power Cold Gun with Dual Point Hose Kit to provide a 2" wide blast of cold air on to the plate and produce an area of the plate which can be held by the operator and speed up production.

Model 5330 High Power Cold Gun System

The Cold Gun Air coolant System produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used.

The Cold Gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet floors.

EXAIR's Cold Gun is non-adjustable to prevent freeze-up during use. Cold airflow and temperature drop are factory set to optimize the gun's cooling capability.
