Özel Gaz Kabine
An exhausted single-cylinder delivery cabinet that combines local containment, an electropolished 316L ultra-high-purity manifold, automatic purge logic, emergency isolation, pressure monitoring and facility interlocks for controlled specialty-gas supply.
- Negative-pressure enclosure for one process-gas cylinder
- Electropolished 316L UHP flow path with face-seal joints
- PLC/HMI purge sequencing, alarms and emergency shutdown
Ürün tanıtımı
The Specialty Gas Cabinet is an active source enclosure for supplying one hazardous or high-purity cylinder to a clean process line. The selected catalogue configuration uses one tall welded light-gray steel cabinet, one secured 47-50 L-class process cylinder, one compact 316L electropolished pressure-control and purge manifold, one flexible cylinder connection, one process outlet, one purge inlet, one top exhaust collar, one local HMI, one three-color beacon and one red emergency-stop control. Normal operation keeps the enclosure connected to facility exhaust while the manifold reduces cylinder pressure, supports evacuation or inert-gas purge sequences and isolates the source when an alarm or external interlock demands shutdown. This is not a passive cylinder storage cupboard, a bare gas panel, a multi-branch valve manifold box or a point-of-use regulator.
Ana Özellikler
Electropolished 316L stainless tubing, diaphragm valves and face-seal fittings support a low-dead-volume ultra-high-purity process path
Automatic purge and evacuation sequences reduce residual process gas before cylinder disconnection or maintenance
A normally closed source-isolation function can respond to emergency stop, gas detection, exhaust-flow loss or a remote facility interlock
Local pressure instruments and HMI status help operators confirm cylinder, delivery and purge conditions before advancing a sequence
A dedicated process outlet and purge inlet keep the delivered gas path distinct from the inert purge supply
Cylinder restraint and an accessible connection zone support controlled changeout without removing the internal manifold
Selectable communications can report alarms, operating state and permissive status to the facility monitoring system
Müşteri Ürün Sorunları
A gas cabinet is only effective when its gas-specific flow path, purge sequence, exhaust duty and shutdown interfaces are selected as one coordinated source system.
A passive cabinet can hold a cylinder but does not provide a controlled UHP delivery path or automatic source isolationUse an integrated delivery cabinet with a gas-compatible regulator, diaphragm valves, pressure monitoring and a normally closed source shutoff tied to the safety logic.
Residual hazardous gas in a pigtail or regulator can expose personnel during cylinder changeoutApply a validated purge-and-evacuation sequence that cycles the isolated connection volume with the selected inert purge source before the fitting is opened.
Loss of exhaust can allow leaked gas to escape the enclosure instead of being carried to the treatment systemMonitor cabinet exhaust flow or differential pressure and interlock process-gas isolation when the required containment airflow is not available.
The wrong seal, regulator or valve material may corrode, permeate or contaminate a reactive high-purity gas streamSelect wetted alloys, seat materials, surface finish and cylinder connection specifically for the named gas, pressure and purity requirement.
Manual valve operation in the wrong order can pressurize a vent path or introduce purge gas into the process lineUse PLC-managed permissives and sequence confirmation so incompatible valve states are prevented and pressure conditions are checked between steps.
A local cabinet alarm may be missed when the source is installed in a remote gas room or sub-fabConnect common alarm, emergency shutdown and operating-status signals to the facility system through hardwired I/O or the selected communications interface.

Teknik parametreler
The catalogue basis is one single-cylinder, fully exhausted UHP delivery cabinet in the CSI single-cabinet and SDC FlexGas class. A representative envelope is approximately 460 mm wide by 480 mm deep by 1930 mm high before site duct and utility connections. The wetted gas path uses 316L electropolished tubing and diaphragm components with orbital welds and metal face-seal joints. Cylinder pressure, delivery pressure, purge state and cabinet permissives are monitored locally; exact regulator range, valve-seat material, cylinder connector, purge method, exhaust collar, detector, sprinkler interface, electrical supply and communications are selected for the actual gas service.
