Single-Bank Manifold Systems
In some applications, specialty gas is used only to calibrate the instrumentation. For example, a continuous emissions monitoring system (commonly referred to as a protocol station) may only require calibration gases to flow for a few minutes each day. A single cylinder manifold with bracket is an ideal solution for this type of application.
Single-bank manifold system is designed for a single source of gas supply from one cylinder bank. Although
this system can be used as a main delivery system, it is typically used in industrial and medical applications
as a high pressure emergency back-up system for liquid vessel or bulk systems.

Multiple Cylinder Manifold Systems
Many applications require a flowrate of gas beyond what can reasonably be supplied by a single station manifold, but are not of such a critical nature that they cannot tolerate occasional shutdown for cylinder changeout. The single header manifold connects two or more cylinders to the same line for continuous gas supply. Each cylinder connection point, or station, is fitted with a valve to permit individual cylinders to be isolated for changeout. In order to preserve system purity, these valves should be the diaphragm packless type to eliminate oxygen, nitrogen, water vapor or other contaminants from entering the gas stream.
dual-bank manifold system consists of a main gas delivery bank and a reserve bank of cylinders.
When the primary cylinder bank is depleted, manually “turn off” the valve on the primary bank and open the valve
on the reserve bank to reactivate gas flow. The changeover of this system needs to be operated manually.
FEATURES

- Silver brazing on piping joints for maximum leak prevention
- System is designed to accomodate future expansion needs
- System is mounted with gas filters
- Pressure switch port is available
- Headers have been tested to withstand high cylinder pressure
- Wall or floor mount available
Semi-Automatic Change-Over
The simplest manifolds are designed to change over based on a sensed drop in pressure of one cylinder bank relative to the other. The regulator pressure gauges must be visually monitored to determine when change-over has occurred.
Differential manifolds require regulator monitoring and resetting and generally are selected for applications where cylinder bank change-over is relatively infrequent, and where a drop in delivery pressure at change-over will not cause a problem.
semi-automatic manifold system is designed to provide an uninterrupted gas supply. It consists of a
primary bank and a reserve bank of cylinders. When the pressure in the primary cylinder bank reduces to the preset
value, the changeover takes place automatically to provide continuous supply of gas from the reserve bank.
Upon changing the cylinders, the regulators on both banks need to be re-adjusted in order for the changeover to
occur automatically next time. The secondary regulator in the main pipeline stabilizes the outlet gas flow.
FEATURES
- Open-style manifold
- Secondary regulator for consistent high flow delivery pressureto the pipeline
- Silver brazing on piping joints for maximum leak prevention
- System is designed to accommodate future expansion needs
- System is mounted with gas filters

Automatic Manifold Systems
A change drop in delivery pressure can, in some instances, result in an adverse effect on instrument performance. To avoid this problem, an automatic manifold may be selected. The operation of this type of manifold is also based on differential pressure, but delivery pressure is held virtually constant during cylinder bank change-over.
When outlet from the primary bank drops to the set pressure of the reserve bank, the reserve bank opens to provide uninterrupted flow of gas.
When used in conjunction with a pressure switch and audio alarm to provide remote indication of change-over, the automatic manifold need not be monitored. Automatic manifolds are used in applications where change-over is relatively frequent and variations in delivery pressure cannot be tolerated. Manual selection of the primary bank is still required after depletion of gas supply.
AutomaticChangeover Regulator Systems provide a reliableuninterrupted supply of gas to a gas pipeline systemin an industrial installation. The ChangeoverSystem consists of a manifold control and twosupply bank headers, one service and one reservesupply, to provide anninterrupted supply of gasfor the specific gas application.The control is designed and built with features
providing automatic changeover from the depleted“Service” supply bank to the “Reserve” supplywith no loss or drop in delivery pressure.Automatic Changeover Regulator Systems is specificallydesigned to regulate and provide uninterruptedgas supply for industrial applications. Deliverypressures are factory-set and are protected insidea tamper-resistant case.
Electronic Logic-Controlled Manifolds
In some critical manufacturing and laboratory processes, an uninterrupted gas supply is an absolute necessity. Failure of the gas supply in these cases could result in loss of an entire lab’s in-process experiments or even shut-down of a production line. A logic-controlled manifold generally is selected for these applications.
By using pressure transducers, the logic-controlled manifold can provide the user with the ability to constantly monitor the pressure in their supply from a remote location. It also can indicate which side of the manifold is currently in use.
When the supply reaches a pre-set pressure, the manifold automatically switches to the reserve side, which continues to deliver gas without interruption. This change-over is accomplished by energizing a solenoid valve, which sends an air signal to open a pneumatic valve on the reserve cylinder bank. At the same time, another solenoid de-energizes to close a pneumatic valve on the supply side, shutting it off. The outlet of both pneumatic valves is connected to the inlet of an internal regulator, which maintains constant delivery pressure.
With the logic-controlled manifold, the danger of inadvertently draining the reserve bank is eliminated since there is no reliance on the operator to switch a change-over valve or reset regulators. Fail-safe operation is ensured by using normally closed pneumatic valves on each cylinder bank. In the event that either electrical power supply should fail, these valves automatically will default to a pre-selected bank to ensure supply of gas.

What we do provide
Gas Cylinders Bundles/Pallet
The POONA ENGINEERS manifolded cylinder pack comes with a hot-dipped galvanised steel frame and strapping that is bolted together. All the required lock nuts and bolts to assemble the unit come with the frame. A manifold is also supplied which is made up of either separate pigtails or one complete manifold. This comes with all the required parts to attach the manifold to the cylinders including POONA ENGINEERS brass cylinder blocks, bullnoses and seals. We also provide valve mounting blocks to install the customer-supplied inlet/outlet valves.
The reason we don’t supply cylinders in our packs is because the paperwork required to purchase them is best managed by the customer. Compressed gas cylinders require documentation for ownership and tracking and so if POONA ENGINEERS purchases this item on behalf of customers, the ownership is then wrongly attributed to us, and not the customer. However, we are always pleased to work with the client to overcome these sorts of obstacles, and make sure that the installation of cylinders to our product is smooth and successful.
We encourage the innovative application of assembly at cylinder manufacturing sites. This would mean a significant reduction in the handling of cylinders as the manufacturer would not have to wrap and package the cylinders for transport and they would experience less damage in transit. We also are happy to send our disassembled frame and manifold anywhere you want it sent – so this could mean at your site or any nominated destination. Due to our flat-pack design, we can send our frame and manifold anywhere in the world for a fraction of the cost of other pre-assembled units.
Valves
The reason we don’t supply the inlet and outlet valves with our cylinder bundle is because they are a highly specialised and personalised component. Each customer prefers a certain make, model and brand of valves and this critical piece is best purchased by the customer at the same time you purchase the pack.
Pallets
