Introduction of High Pressure Nitrogen Generator for Laser Cutting

A full PSA nitrogen generation system requires air compressor, refrigerated air dryer, filters, air tank, nitrogen generator/nitrogen equipment and gas buffer tank.

We supply full installations but each component, and other optional supply like boosters, high pressure compressors or filling stations can also be bought separately.

Application of Nitrogen Machine in Metal Works

Laser Cutting
In laser cutting the laser beam melts the material and high-pressure nitrogen forces the metal quickly to harden. As nitrogen has a shielding effect and inert properties, the cutting area is protected against‘slag/bluing’ and oxidation and discoloration in the heat of laser The higher your demand for a high-quality clean cut is, the greater your need for nitrogen purity. Stainless steel requires a higher purity than‘normal’ steel and metal.
Brazing is a process that is well matched for PSA generated N2. Nitrogen provides a blanket over the product that prevents decolorization and oxidation during brazing process. At 99.5% purity, some decolorization occurs, but there is still very little oxidation and no structural impact on the braze itself. Your choice of purity is really dependent only on the importance of the finished look of your product.
Leak Check
What is a leak? A leak is an unintended opening, hole or porosity in a containing wall that allows the escape of gas or fluid. Nitrogen is used to detect leaks in a variety of plumbing or piping applications. The gas is injected under pressure to assure good connections in brazing, welding and threaded pipe fittings.


Convenience of On-site Nitrogen Generator

Our PSA Nitrogen Generator reduces operator intervention and the high-labor cost, systems operate entirely automatically, in direct response to demand in the downstream distribution system. No more worries about downtime created by late deliveries, weather related influences, unexpected empties and loss of expensive cylinders. Elimination of supplier dependence is a key to greater control and efficiency. In fact, multi-level sayings are realized as nitrogen gas costs are paid via your electrical bill, thereby eliminating bookkeeping, purchasing, inventory record keeping, contract negotiation and other management involvement altogether. This convenience really saves money at bottom line.

Questions & Answers

Q: How many square feet do we need for it?

A: The system is quite flexible to set-up and can be lined up along a wall or in the middle of a room. There are Five Components and an Air Receiver Tank is also required if the system is not close to one. The PSA will vary in size by the required capacity.

Q: What is sieve protection shutdown?

A: The sieve protection shutdown is a pressure switch that is set-up to shut the system down if there is a drop in air pressure. The reason we put this on every system is to protect the system from an oil incursion that might be caused by an air compressor failure. Air compressors sometimes fail and can pump oil into a system. Oil will cause damage to the carbon sieve material so we have engineered the system to protect itself as well as possible.

Q: Will our own compressor be sufficient to support this system?

A: After calculated, if the specifications of your air compressor is ok, then can use it. Details as specified in the proposal.


Which Nitrogen Generator Should I Choose?

Different parameters are essential for your choice of nitrogen generator.
• Which nitrogen capacity do you need?
• Which pressure is required?
• What purity is required?

This is our standard range of nitrogen generators. If you have other requirements we will be happy to produce a generator that matches your needs.

Please feel free to send us your detailed requirements, you would be satisfied with our service.
