Matheson offers a configured single cylinder gas cabinet with a 5300 Series Analytical Grade Panel for hydrogen service. All piping penetrations are through the top of the cabinet through a bulkhead plate.

Standard Configuration

• 1177 Single Cylinder Gas Cabinet 

The Model 1170 is our most popular gas cabinet series with a flat top design. The construction is optimized for economy, without compromising safety or quality.

• 5000 Series Panel 

Matheson's PAN-5000 Series of analytical grade stainless steel gas panels that are designed to safely control and dispense gases, while providing a high level of process purity. The PAN-5000 Series panels feature Matheson components that have a proven track record in analytical laboratories and chemical process industries worldwide. Use of these analytical distribution panels with a Matheson gas cabinet enclosure provides the high level of safety required when handling corrosive, flammable or toxic gases.

Panel

• 5300 Series
This 3-valve panel provides a pressure regulator with both a process on/off control valve and a high pressure vent valve, allowing total isolation of the regulator, as well as the ability to purge contaminants that may have been introduced by changing cylinders. The vent line is protected from back flow by a check valve downstream of the vent valve. This panel is recommended when using non-toxic, non-corrosive, and non-pyrophoric gases with processes that require the additional purity that a high pressure purge is capable of supplying.  Each CGA contains an integral check valve. 

Gas Connections

• Process Gas Outlet: 1/4" Swagelok
• Flex Hose: 350 CGA

	Low Cylinder Indication
	Intrinsically Safe Pressure Switch The Class 1 Div 1 & 2 intrinsically safe pressure switch is the Ashcroft F series and is useful when remote monitoring of a gas supply is desired.  It is set to 300 psi decreasing and can be adjusted by the customer.
	Pressure Monitor (PM-24) The Matheson Pressure Monitor, Model PM-24, was designed as a method of monitoring a gas supply, when used in conjunction with Matheson Gas Delivery Systems with Pressure Switches.  The PM-24 will indicate the status of gas supply: FULL – IN SERVICE, and DEPLETED. When a cylinder or cylinder bank is depleted, the green light will change to a red light, and the audible alarm will sound. The audible alarm can be silenced, leaving the red light indication. The red light will automatically reset to green when the depleted cylinder is replaced with a full cylinder.

	Recommended Safety Package
	Gas Detection The Hydrogen LEL (GSM Series) Gas Sensor is able to detect any dangerous leaks and is typically coupled with a GSM-12 Controller and an ESO valve.
	GSM-12 Shutdown Controller< The GSM-12 controller is typically used to operate a pneumatically operated, normally closed, emergency shutoff valve (ESO) on a gas panel. It has ten sets of contacts for alarm conditions: • Excess Flow • Exhaust Failure • Gas Detector Warning • Gas Detector Alarm • Fire Detector • Low Cylinder Contents (by pressure or weight) • High Delivery Pressure • Process Line Containment • Remote Start • Remote Shutdown (Sensors ordered separately) Delay times between when a fault condition is first sensed and when an actual shutdown or alarm occurs have been programmed to avoid any nuisance alarm tripping. The controller also has an ABORT button on the front for manual shutdown.
	Emergency Shutoff Valve (ESO) The 4384 Series Air Operated Valve is Normally Closed (NC). It is installed at the inlet of the panel and is operated by the GSM-12 Controller. It has a diaphragm seal for high purity and low diffusion.

Other Options

	Other Shutdown Options
	Excess Flow Switch (EFS) The excess flow switch (Size D) is installed on the outlet of the panel and is typically coupled with a GSM-12 Controller and an ESO valve.  The set point increases when the pressure increases and will trip between 10 and 20 SLPM (30 PSI)
	Excess Flow Valve (EFV) The 6290 Series Excess Flow Control Valve is a sensitive excess flow shut-off valve  installed on the outlet of the panel and is designed to operate with a wide range of inlet pressures.
	Exhaust Failure Switch (option X) Switch used to indicate low exhaust suction. This is a popular option with the GSM-12

	Ventilation Options
	Magnahelic (option M) Gives visual status of exhaust suction (option M). This is often paired with the exhaust failure switch Range: 0-3" WC
	Fusible Link (option L) Blocks air from entering cabinet in case of fire. Temperature rating: 165 F Approvals - UL & C-UL Listed and FM Approved
	Diffuser Plate with Filter (option D) To prevent small particulates from entering the cabinet interior.
