IoT-Monitored 7.5m³ Industrial Cryogenic Tank

| Product Overview

Basic Structure & Specifications

The 7.5m³ Cryogenic Tank developed by Gansu Shenleng Cryogenic Equipment Co., Ltd. is a high-performance mobile self-pressurized low-temperature storage device. It adopts a multi-layer winding high vacuum insulation method to achieve excellent thermal insulation performance. The tank has an inner container made of S30408 stainless steel and an outer shell of Q345R steel. The inner container is suspended in the outer shell by a supporting device, and the space between the inner and outer layers is evacuated and filled with insulation materials to ensure low evaporation loss.

Core Configuration

This product covers three specification models with geometric volume of 7500L and effective volume of 7125L, mainly used for storage and supply of liquid oxygen (LO₂), liquid nitrogen (LN₂) and liquid argon (LAr). Equipped with China’s first electronic scale with high measurement accuracy, it enables on-site settlement without tank truck weighing. Optional liquid level remote transmission system realizes IoT-based remote monitoring. With overall dimensions of 2250×2250×3864mm and elegant appearance, it fits various indoor and outdoor scenarios.

| Core Advantages

Flexible Gas Supply Solution

Multiple storage tanks can be combined to supply mixed gases according to different processing requirements of customers, meeting diversified needs of industries such as laser processing and metal welding without being limited by single gas supply mode.

High Purity & Low Pollution

It provides high-purity gas supply, replacing traditional steel cylinders and dewar flasks. This reduces cylinder replacement frequency and avoids gas pollution during replacement, ensuring stable gas quality for precision operations.

Energy-Saving & High Efficiency

Featured with fast charging speed, high gas quality and slow self-pressurization speed, the high-efficiency insulation structure ensures ultra-low power consumption, and even zero power consumption can be achieved in specific working conditions.

Zero Wastage Filling

It supports filling by transport tank trucks and automatic liquid filling vehicles, realizing zero wastage in the filling process. On-site filling solutions are also available to help customers build centralized gas supply systems.

| Application Fields

Laboratory & Scientific Research

It supplies liquid nitrogen for chemical, physical and material laboratories in universities, scientific research institutions and enterprise R&D centers, supporting low-temperature experiments and material performance testing.

Metal Processing & Manufacturing

It is applicable for cold assembly of shaft sleeves and other parts, as well as low-temperature material performance testing. It also provides protective gas sources for argon arc welding and other precision welding processes.

Food Processing & Fresh-Keeping

It supplies liquid nitrogen for small food processing lines or experimental lines, realizing quick freezing of high-end seafood, fruits and pastries to retain freshness and original taste. It can also serve as a temporary cold source for cold chain transportation.

Multi-Industry Supporting

In electronics & semiconductors industry, it provides cooling and oxygen-free environment for production. In beauty industry, it supports cryolipolysis projects. It also acts as emergency standby gas source for remote sites without centralized gas supply.

| Operation & Safety Guidelines

Standard Operation Norms

Operators must receive professional training and master the tank’s operating procedures. During filling, check pipeline tightness and valve working status thoroughly to prevent liquid leakage and ensure safe operation.

Safety Protection Measures

The tank is equipped with safety valves and bursting discs with model-specific pressure parameters. For instance, the 7.5/1.6 model has a safety pressure of 1.7MPa and bursting disc pressure of 1.81MPa. Regular inspection of safety accessories is required to ensure sensitivity and effectiveness.

Daily Maintenance Requirements

Regularly check the tank’s vacuum degree and insulation layer integrity. Record daily evaporation rate, which shall not exceed 0.4% for liquid nitrogen to maintain stable performance.

| Production Process

Material Processing & Forming

High-quality S30408 stainless steel and Q345R steel are selected and cut according to design dimensions. The inner container and outer shell are formed by stamping and rolling processes to meet structural strength requirements.

Welding & Quality Inspection

Precision welding is performed on inner and outer containers, followed by non-destructive testing to ensure welding quality meets national standards and no defects exist.

Insulation & Vacuum Treatment

Supporting devices are installed, insulation materials are filled between inner and outer layers, and the interlayer is evacuated to achieve high vacuum insulation effect and reduce evaporation loss.

Assembly, Commissioning & Delivery

Electronic scales, liquid level remote transmission systems, valves and other accessories are installed. Overall commissioning is conducted to ensure all functions are normal, and delivery is arranged after passing pressure test, leakage test and other quality inspections.
