The HENGNA 1900mm Single Gas Cylinder Cabinet is designed specifically for university research settings. It provides intelligent gas leak detection and an automatic fan system that activates within seconds of a leak. The single‑bottle configuration is ideal for labs that use one gas at a time or have limited floor space. And because universities operate on tight budgets, this cabinet delivers professional‑grade safety at a price that fits academic purchasing.
This guide explains how this cabinet supports safe, efficient research at California's top universities.

Why California Research Universities Choose This Cabinet
1. Intelligent Gas Leakage Detection
The integrated combustible gas sensor continuously monitors the inside of the cabinet. It is calibrated to detect a wide range of flammable gases commonly used in university research: methane, propane, hydrogen, acetylene, and others. When gas concentration reaches a preset level, the system triggers.
This is not a passive device—it's actively watching, 24 hours a day, 7 days a week. Even when the lab is empty at night or on weekends, the sensor remains vigilant.
2. Automatic Fan System – 5‑Second Response
When a leak is detected, the MAXAR exhaust fan activates within 5 seconds. This rapid response prevents gas from accumulating inside the cabinet, reducing the risk of fire or explosion. The fan pulls the leaked gas out of the cabinet and into the lab's ventilation system (or outside, depending on facility configuration).
The fan continues to run until gas levels drop below the alarm threshold, then shuts off automatically. No manual reset is required—the system handles everything.
3. Perfect for Single‑Bottle Applications
Many university labs use only one gas at a time. The single‑bottle cabinet is compact (500mm wide) and fits easily in tight lab spaces—against a wall, under a fume hood, or in a corner. It's also ideal for:
Specialized instruments that require a dedicated gas supply
Teaching labs where multiple stations each need their own gas cylinder
Satellite storage areas throughout a research building
4. Built for Academic Environments
Universities have unique needs:
High turnover of users: New students arrive each semester. The cabinet is simple to operate—open, secure chains, close. Minimal training required.
Varied gas types: The combustible sensor works for most flammable lab gases. For non‑flammable gases, the physical safety features (chains, glass window) still provide essential protection.
Budget awareness: This cabinet delivers core intelligent safety features at a price that fits grant funding and departmental budgets.
Designed for Lab Use
Material and Durability
| Layer | Material | Function |
|---|---|---|
| Base | Cold‑rolled steel (1.2mm) | Structural strength |
| Conversion | Phosphorus‑free treatment | Environmentally friendly, improves coating adhesion |
| Powder coat | Epoxy resin | Resists chemical spills and lab cleaners |
| Topcoat | Scratch‑resistant finish | Maintains appearance despite frequent use |
The epoxy coating is resistant to common lab chemicals—ethanol, isopropanol, dilute acids—and can be wiped down with disinfectants.
Physical Safety Features
Retaining chains: Secure the cylinder firmly in place. Chains are coated to resist rust and have easy‑to‑use hooks.
Removable bottom plate: Allows the cylinder to be rolled in and out without lifting. This is especially helpful when changing heavy cylinders.
Explosion‑proof window: Tempered glass lets researchers check pressure gauges and cylinder labels without opening the door—improving safety and convenience.
Anti‑tip stability: The cabinet's footprint and weight keep it stable. Optional floor anchors are available for added security.
How It Works: Step by Step
Normal Operation
Cylinder is loaded using the removable bottom plate.
Retaining chains are secured around the cylinder.
Door is closed and locked.
Sensor continuously monitors internal atmosphere.
Green indicator light (if equipped) shows system is operational.
Leak Detection
Gas sensor detects concentration above preset threshold.
Within 5 seconds:
MAXAR exhaust fan starts automatically.
Audible alarm sounds (85dB).
Red light flashes.
Fan runs until gas levels return to safe range.
Alarms stop automatically once conditions are safe.
What Researchers Should Do
If alarm sounds, evacuate the immediate area if necessary.
Identify the source of the leak (cylinder valve, regulator connection).
Close the cylinder valve if safe to do so.
Ventilate the lab according to your safety protocol.
Contact lab safety officer or facilities for follow‑up.
Applications Across California Universities
| Department | Typical Gases | Why This Cabinet Works |
|---|---|---|
| Chemistry | Hydrogen, methane, acetylene | Flammable gas detection and rapid exhaust protect against fire risks |
| Materials Science | Argon, nitrogen, oxygen | Physical restraint and glass window for visual checks; optional oxygen sensor available |
| Biology | CO₂, nitrogen (for cell culture) | Inert gases need only physical safety; cabinet provides secure storage |
| Physics | Helium, neon, xenon | Compact size fits in crowded lab spaces; explosion‑proof window protects valuable equipment nearby |
| Engineering | Various gases for experiments | Versatile design accommodates different cylinder sizes |
Frequently Asked Questions
Q1: What gases does the combustible detector sense?
The standard sensor detects flammable gases and vapors, including:
Methane
Propane
Hydrogen
Acetylene
Ethylene
Natural gas components
It is not designed for toxic gases like carbon monoxide or ammonia, nor does it detect oxygen levels. If your lab uses those gases, please contact us for sensor options.
Q2: Can this cabinet be used for non‑flammable gases like nitrogen or argon?
Absolutely. Even though the alarm system may not be needed for inert gases, the physical safety features—retaining chains, removable bottom plate, explosion‑proof window—are valuable for any gas cylinder. You can order the cabinet with or without the sensor/fan system.
Q3: How do I maintain the sensor and fan?
Sensor calibration: Recommended annually. Calibration kits are available, or you can return the sensor to HENGNA for factory service.
Fan test: Press the test button (if equipped) monthly to verify fan operation.
Cleaning: Wipe the exterior with a damp cloth; avoid spraying cleaners directly into the sensor or fan vents.
