I. Overview

The PGN-30LB High Purity Nitrogen Generator is suitable for various liquid chromatography systems (high pressure) both domestically and internationally. It is widely used in laboratory analysis and testing departments in the oil, chemical, coal, pharmaceutical, food, beverage, environmental protection, indoor testing, health, quarantine, power, public security, and universities.

The High Purity Nitrogen Generator is powered by an air compressor as the raw gas source, featuring a superior dual compressor, self-designed vibration and heat insulation measures, an automatic drainage system, a cooling system, a gas purification and filtration system, and an internal overpressure safety protection device. Advanced membrane separation technology is employed, significantly enhancing the nitrogen production efficiency and purity, earning widespread customer recognition and positive reviews.

The gas storage tank is made of premium stainless steel material, featuring a dual protection system against overpressure and overcurrent. The operation is simple, reliable, and ensures the continuous stability of the machine's operation.

The machine's air circuit is divided into two main parts: the first is air compression and storage, and the second is membrane nitrogen separation. The power source for compression and storage is the compressor. Once the circuit is connected, the compressor begins to compress and store gas. It will automatically stop when the pressure reaches the set value. The nitrogen production process consumes air, and the compressor will automatically start to replenish air when the air pressure falls below the set value. The nitrogen production process uses membrane separation. When the air pressure reaches the nitrogen production requirements, the nitrogen production switch is turned on, and a pressure stabilizing and throttling device is connected in the nitrogen gas circuit. The PGN-30LB high-purity nitrogen generator is a large flow product developed by our company based on the original model to meet customer needs, and it holds a leading position in the market.

This instrument is highly suitable for large-scale supply. The machine has increased the compressor power and nitrogen membrane separation material. Our company boasts mature technology and processes, effortlessly handling continuous, high-load operations. The nitrogen generator, due to its mature technology, ease of use, low cost of gas production, and high purity, has long been replacing steel cylinders. It is increasingly chosen by laboratories, leading to the complete elimination of expensive and dangerous high-pressure steel cylinders from laboratories.
