Introduction
A nitrogen generator is an on-site gas production system that extracts nitrogen gas (N₂) directly from compressed air, eliminating the need for third-party nitrogen deliveries (cylinders or liquid dewars). It uses air separation technology to isolate nitrogen molecules from other atmospheric gases.
As an original manufacturer, we deliver customers all over the world nitrogen generators with purity up to 95%-99.999% serving various industries. Scala nitorgen generators range from desktop generators to all-in-one model and nitrogen generators with gas containers, with nitrogen flow rate from 1Nm³/hr to 2000Nm³/hr.
Our team - comprised of seasoned industry veterans, dynamic mid-career experts, and emerging young talent - drives the continuous development of next-generation nitrogen generation systems.
Flow Chart of Nitrogen Generation
Typically, nitrogen generation requires equipments as blow.
1. Air Compressor
· Function: Provides compressed air (typically at 7-10 bar) as the feed gas for nitrogen generation.
· Types: Oil-injected or oil-free screw compressors, depending on purity requirements.
2. Air Receiver Tank (Buffer Tank)
· Function: Stores compressed air to ensure a steady supply, reducing pressure fluctuations and acting as a buffer.
3. Air Dryer (Refrigerant or Desiccant)
· Function: Removes moisture from compressed air to prevent condensation, which can damage downstream equipment.
· Types:
Refrigerant Dryer: Cools air to remove water.
Desiccant Dryer: Uses adsorbent materials (e.g., silica gel) for very dry air (needed for high-purity nitrogen).
4. Particulate Filters (Pre-Filtration)
· Function: Removes oil aerosols, dust, and solid particles from the compressed air before it enters the nitrogen generator.
· Common Types:
Coalescing Filter: Removes oil and water droplets.
Activated Carbon Filter: Adsorbs oil vapors and odor.
5. Nitrogen Generator
Scala provide customers with both dual-tower PSA nitrogen generators and modular nitrogen generators, which can continuously producing nitrogen at apressure of 0.7-1.3Mpa with purity 95%~99.999%, capacity ranges from 1Nm³ per hour to 2000Nm³ per hour.
On-site Nitrogen Generation vs Nitrogen Bottle Deliver
On-site nitrogen generator is an excellent long-term choice for high-volume / continuous nitrogen users and a perfect replacement for nitrogen bottles. Bulky nitrogen cylinders wastes space and there would be potential risks to handle the high pressure equipments. On-site nitrogen generation redeces waste and offer on-demand purity with 24/7 continous supply.
Bottled N2 Supply
· Complex opeartion, a pressure reducing valve and control system are needed.
· Ever-present safety risk, heavy vessels containing gas under high pressure.
· Rental/delivery problems, you may forget to order, delivery delay, storage spaces, etc.
· Routine work trouble, you may need order, arrange payment and a lot of checkings.
· Higher cost, regular consumer of nitrogen rely on bottled nitrogen gas may be very costly in the long run.
On site N2 Generation
· Safe and fast, saves you the trouble of handling or purchasing, etc.
· Pressure controllable, continuous nitrogen gas production without interruption.
· Easy to use, plug and play, fully automatic running, saves pernel on duty.
· Portable, flexible and convenient, eliminates the hassle of transportation..
· Cost effective, only electricity consumption cost which will save you lots of money for one-time investment.

Application of Nitrogen
As an inert, colorless, odorless gas, nitrogen is widely used in diverse applications across multiple industries due to its non-reactive properties, ability to displace oxygen, and cooling capabilities when liquefided.
1. Food & Beverage Industry
· Modified Atmosphere Packaging (MAP): Replaces oxygen to extend shelf life (prevents oxidation and spoilage).
· Blanketing: Protects wines, oils, and juices from oxidation during storage and bottling.
· Freezing & Chilling: Used in cryogenic freezing (liquid nitrogen at -196°C) for quick freezing (e.g., seafood, meat, vegetables).
· Beer & Soft Drink Dispensing: Provides pressure for kegs without altering taste.
2. Pharmaceutical & Healthcare
· Drug Manufacturing: Prevents oxidation in sensitive chemical processes.
· Blanketing: Protects vaccines, medicines, and biologics from contamination.
· Medical Gas Mixtures: Used in respiratory therapies (mixed with oxygen).
· Cryopreservation: Freezes and stores biological samples (sperm, eggs, stem cells).
3. Electronics & Semiconductor Manufacturing
· Soldering & Reflow Ovens: Prevents oxidation during PCB assembly.
· Wafer Fabrication: Creates inert atmospheres in cleanrooms.
