For safety reasons, the pipeline connection is different than the cylinder, and is rated at a lower maximum working pressure. The argon cylinder regulator/flow meter has a CGA 580 inlet connection, where as the pipeline connection for an argon regulator is CGA 034. In most instances, only a flow meter is used at the station drop outlet (“B” size outlet, 5/8” -18 CGA 032) with the pressure being maintained by the gas manifold.

Also, there is a performance issue when using the regulator/flow meter designed for high pressure cylinders. Normally the pipeline pressure is lower than what manufacturers require for the minimum inlet pressure to obtain the stated flow rate performance.

Yes, the fully automatic manifold uses patented technology that gives you the flexibility to use either low pressure (Liquid dewers) or high pressure cylinders on each side or a combination of low and high pressure cylinders with the same control cabinet. This flexibility eliminates the requirement of using a separate manifold when wanting to use, or change to low and/or high pressure cylinders.

The materials used in the construction of Specialty gas manifolds have been upgraded to use diffusion resistant valves, pigtails, & regulators. Also, specialty gas regulators feature stainless steel diaphragms and have a helium leak rating. Brass regulator rating is 1 x 10-8 cc/sec., & for stainless steel, 1 x 10-9 cc/sec. The features of each system remain unchanged.

In general, an industrial application return on investment is 1 yr or less. In an application that uses 3-cylinders of gas per week, you can have a rapid payback of 1 year or less. Call to have us do a ROI analysis for you.

A secondary advantage of owning a manifold system in addition to the economical savings is increased safety by eliminating the handling of cylinders throughout the workplace.

Medical manifold systems are built with additional redundancy and failsafe features to ensure a continuous operation in the event of a component failure.

Our systems are complete with all items that you need to install the system and connect your cylinders to the pipeline. We also include the extras that will be needed for the installation to meet industry standards, such as cylinder racks/chains, and pipeline safety relief valve.

Precise Equipment has the flexibility to design systems for even the most unique applications.

The PDL series is for use with low-pressure (Liquid dewers) cylinders, with a maximum inlet pressure rating of 500 psig. The PDH series is designed for using high pressure cylinders with a maximum inlet pressure of 3000 psig.

Based on the industry standards, the portion of the fuel gas system that is mixed with oxygen requires a pipeline flashback arrester.

In figuring pipe size, the 3 things we consider are (1) how long the run is, (2) what pressure (PSIG) you will use in the pipeline, and (3) what is the flow rate (CFH) that you will be using . Give us a call and we will be happy to help you select the correct size for your application.

The industry standards do not specify composite pipe as an acceptable material for pure oxygen service. Our recommendation is not to exceed 15% oxygen in an inert gas mix.

The correct method that meets the industry standards is to use a station drop with single or multiple outs. Station drops are designed and manufactured to meet multiple industry pipeline outlet requirements such as shut-off valves, check valves, “B” size (Hose), or “C” size (Station regulators) outlet fittings, outlet fittings plugs or caps, condensation trap, and labeled for the particular gas service.

The fully automatic gas systems can be used with either low-pressure or high-pressure cylinders interchangeably. The more economical pressure differentials are designed to use a specific type of cylinder only.

The fully automatic has additional features such as 6-system status LED’s, digital pressure readout, and standby cylinder bank leak detection.

When using a combination of low & high pressure gas cylinders, or a micro bulk and high- pressure cylinders, the fully automatic can be prioritized to always use the low-pressure source first.

Pressure differential models are mechanical and do not require power to operate.

No, the default position is “None” (“FIFO” on earlier models) but, if using a combination of low and high pressure gas cylinders; the low pressure cylinders could be set to always be the primary supply (Prioritized side). The priority side (left or right) will always be either in-use or empty, but never be in standby mode.

For safety reasons, the pipeline regulator connection is a different connection than the cylinder and is rated at a lower maximum working pressure. As an example, a standard oxygen cylinder regulator has a CGA 540 inlet connection, and the industry standard for an oxygen pipeline regulator is CGA 024 (“C” size, 7/8”-14 RH), thus preventing the two regulators to be used interchangeably. For fuel gas, the pipeline regulator connection is CGA 025 (“C” size, 7/8”-14 LH).

Also, there is a lack of performance issue when using a cylinder regulator designed to operate with an inlet pressure greater than the normal pipeline pressure.
