Matheson’s 3D Pro Automatic Switchover Systems are designed to provide a continuous supply of gas for your 3D metal printer. The 3D Pro System safely minimizes repetitive cylinder change out labor while offering a safe and efficient method of connecting multiple cylinders to a common gas supply line to provide centralized distribution of gas for both high purity 3D metal printing applications. The purifier panel ensures that the highest quality of gases are delivered to your process.

Applications

• 3D metal printing sinter furnace
• Other applications needing high purity gas

Design Features

• Ideal for High (UHP 99.999%+) or Low Purity gas delivery.
• Provides automated switchover control and gas delivery for two cylinders.
• Utilizes Matheson’s single body Switchover Regulator.
• Compact design minimizes wall space consumption.
• Switchover regulator knob indicates cylinder (bank) priority.
• Relief valve upstream of line regulator acts like an interstage relief valve.
• Maximum inlet pressure up to 3000 psig.
• Design allows convenient access to all components.
• Optional features allow customized system design for specific gas delivery applications.

Standard Configuration

• 200 psig +/- 20 psi switchover pressure
• 150 psig delivery pressure
• CGA connections with integral check valves
• 1/4” compression tube outlet connection
• Mounted on U-Channel

Options

Inlet Connection
350 CGA Hydrogen, many flammable gases, and most gas mixtures with flammable components
580 CGA Inert gases such as Nitrogen, Argon, and Helium

Flex Hose Length
3 foot (Standard) Works well with most cylinders.  Flex Hose Assembly - Armored (3 Foot Long)
6 foot Useful when hard to position cylinder bundles or dewars are the gas source.  Flex Hose Assembly - Armored (6 Foot Long)

Inlet Gauges
3000 psig Gauges - Standard 2" dial stainless steel pressure gauge. Pressure Gauge (SS)
Smart Gauges (Gas Watcher) Bluetooth wireless devices (Gas Watcher^TM ) that can display gas operating pressure in "real time" locally on the device itself or remotely via connection to a web based portal. The operation and control settings for the Smart Pressure Gauge are accessed through a set of two push buttons located on the face of the Smart Pressure Gauge.
Smart Gauges (Gas Watcher) with Router The above Smart Gauges (Gas Watcher) with Receiver/Router and an Annual Monitoring/Reporting Service (first year included with Receiver/Router).  The router is required if the user wants to access the pressure remotely on a computer, tablet or smart phone.  The router can handle up to 49 devices.

Accessories
