Ammonia Gas Cabinet with 5-Valve Panel

Product Description

Matheson offers a configured single cylinder gas cabinet with a 5500 Series Analytical Grade Panel. 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.

Panel Options

• 5500 Series
This 5-valve panel, with rigid pigtail, provides a 3610A Series 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 also has a low-pressure vent valve, and adds the safety feature of being able to cycle purge the panel with an inert gas during a cylinder changeout. This panel provides the safety needed to handle toxic and corrosive gases. The 5-valve panel is available with an optional venturi for vacuum evacuation of the panel during purging. Unlike the 1- and 3- valve designs, CGA’s do not contain integral check valves.

Gas Connections

• Process Gas Outlet: 1/4" Swagelok
• Purge Gas Inlet: 1/4" Swagelok

	Recommended Safety Package
	Gas Detection Gas Specific (GSD 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.
