Product advantages1. Efficient insulation, energy saving and consumption reduction
- Adopting multi-layer vacuum powder insulation technology, the vacuum degree of the interlayer is ≤2Pa, combined with high-purity pearl sand filling, effectively reducing heat conduction, daily evaporation rate ≤0.2%, saving 15%-20% energy compared with traditional storage tanks.
- Equipped with double safety valves, bursting discs and pressure remote monitoring system, automatic pressure relief when overpressure;
- The inner tank is made of 304 stainless steel, which has strong corrosion resistance and a service life of more than 20 years;
- The vacuum interlayer is equipped with a radiation shield to prevent external heat radiation from causing the storage tank to heat up.
- Compact structure, support vertical or horizontal installation, small footprint;
- Modular design, support container transportation, reduce international logistics costs;
- The interface position and specifications can be customized according to customer needs to adapt to different filling equipment.
- Integrated level gauge, pressure gauge and temperature sensor, supporting remote data transmission;
- Provide Internet of Things (IoT) module to achieve real-time monitoring and early warning of storage tank status;
- Equipped with professional maintenance manuals and 24-hour after-sales team to ensure stable operation of the equipment.
