A privacy fence is a type of fencing that is designed to provide privacy and security to a property. Privacy fences are commonly used to enclose backyards, swimming pools, and other outdoor living spaces. They can also be used to block noise, wind, and other elements from entering the property. Privacy fences can be customized to fit the specific needs and style preferences of the property owner.

The NG series high-purity nitrogen generator is designed with a compact and lightweight structure, offering exceptional gas purity and automatic flow tracking. It features advanced automatic emptying and anti-overflow systems to enhance automation and safety. A low water level warning system ensures the electrolytic cell is protected, making the operation more convenient, secure, and reliable for users.
This instrument can operate either intermittently or continuously, making it an ideal alternative to traditional gas cylinders in laboratory settings. It meets the requirements of all major gas chromatograph manufacturers worldwide, regardless of the model or type. Widely applied in industries such as petroleum, chemicals, pesticides, fertilizers, power, tobacco, pharmaceuticals, winemaking, water treatment, environmental monitoring, public health, and academic research institutions, it has become a versatile and essential tool.
The NG series utilizes single-liquid, single-cathode electrolysis and catalytic technology, using purified air as the raw material and potassium hydroxide solution as the medium. Through physical adsorption and electrochemical separation, oxygen is removed from the air, while nitrogen is generated and purified. As the purified air enters the cathode side of the electrolytic cell via a high-precision voltage regulator, oxygen is chemically separated through a diaphragm and collected on the anode side before being evacuated. The nitrogen on the cathode side undergoes further purification by removing residual oxygen through a catalytic device and a secondary filtration stage, resulting in high-purity nitrogen that exits through the gas outlet.
The generator is equipped with a programmable control system that automatically adjusts the nitrogen flow rate based on the actual gas demand of the gas chromatograph. This ensures stable gas production with automatic pressure and current regulation, maintaining consistent performance over time.
Additionally, the unit includes an anti-overflow mechanism and a low water level alert to prevent accidents caused by user error. An anti-vibration and anti-aging filter helps extend the lifespan of the equipment, ensuring long-term reliability and efficiency.
