Dongda Haicang, West to Taihang, South to Jianghuai, North to the Imperial Capital. Tianjin Rongao Pusai Gas Regulation Preservation Technology Co., Ltd. (RIAOPUS) is registered in the beautiful coastal city of Tianjin, a national high-tech production enterprise specializing in the design, production, sales, installation, and technical service of gas regulation preservation equipment. Our production facility spans 4,800 square meters and has passed the ISO9001:2008 quality system certification and the EU export CE certification. As a player in the gas regulation industry, our company has a military-industrial background and is a manufacturing enterprise. Our technical team includes some of the earliest and most experienced experts in the gas regulation field, with over 20 years of experience in the research and development of gas regulation storage and military ship preservation. Committed to technological innovation, energy conservation, environmental protection, honesty, and quality, our company has gathered a multitude of professional talents in the industry. Our goal is to design and innovate high-quality, energy-saving gas regulation products to provide customers with an excellent experience. We strictly focus on three aspects: gas separation systems, fruit and vegetable preservation systems, and low-oxygen storage systems. Our operational system is gradually achieving the development objectives of systematic organization, scientific decision-making, standardized management, procedural work, and standardized efficiency. We are steadfast in our business development strategy, determined to be a channel distributor in the gas regulation equipment production industry, and dedicated to serving refrigeration engineers across the nation. Through preservation technology services and technical support for the construction of gas regulation warehouses, we closely collaborate with a wide range of refrigeration engineers, continuously promoting the rapid development of China's gas regulation preservation industry. As a one-stop gas regulation equipment production enterprise that specializes in serving engineering channel merchants and does not undertake comprehensive gas regulation refrigeration projects, we are a model in the industry. Moreover, our gas regulation products are exported to more than a dozen countries in Asia, Africa, South America, and Eastern Europe, receiving unanimous praise from international customers.

Our fruit and vegetable preservation oxygen reduction system utilizes advanced adsorption tower design and manufacturing techniques, along with a permanent magnet variable frequency air source system. We have introduced international precision pipeline distribution and adsorption time optimization design to ensure energy-saving effects during the oxygen reduction process. The mechanical clamping ensures a longer lifespan for molecular sieve, while a multi-component control structure guarantees ultra-low gas consumption ratios. The purity of the preservation nitrogen gas can reach 99.9% or higher. The intelligent oxygen reduction machine for fruits and vegetables consumes only 0.8 kW/h of electricity, making it a stable, widely used, and cost-effective oxygen reduction technology in China. It is at a high level in terms of oxygen reduction, energy saving, and consumption reduction. The oxygen regulation equipment control system components and sensors are imported from Europe and feature multiple patented technologies. Our oxygen regulation products are energy-efficient, reliable, with mature technology and high detection accuracy, capable of fully automated control of various values and stable operation. In today's rapidly advancing information technology, we are willing to cooperate with customers across the country who are dedicated to promoting the development of the oxygen regulation preservation industry in various ways, seeking mutual benefits and common development, and contributing to the cause of China's oxygen regulation preservation!
