Pressure Reducing System

Pressure Reducing System Home

Features

We offer complete Hydrogen Unloading / Pressure Reducing Stations to suit your specific process requirement, right from pigtail and manifold to connect cylinders / truck trolley, auto Manifold change over pressure reducing station, safety shut off, safety interlocks, flow measurement etc., generally, supplied as complete skid mounted ready to use unit.

Hydrogen Unloading Stations have been supplied for flows as high as 4000 NM³/Hr.
Simple design with highly reliable & easy maintain components.

"Onus" Hydrogen Unloading Station is the most safe method of Hydrogen Consumption as it has built - in safety shut off arrangement with 100% redundant safety measures. Additional safety interlocks can be incorporated as per process requirements. Provision of Nitrogen purging for safe operation.

Due to very low pressure drop technology adopted in design of the Hydrogen Unloading Station, Hydrogen in cylinders is fully utilized. Thus system pays back by ensuring fast and maximum possible emptying of Hydrogen Cylinders, reducing batch time and reducing No. of cylinders change over compared to other means of Hydrogen Unloading.

No electrical or pneumatic supply is required to ensure normal working and safety shut-off operation.

High accuracy in control of final outlet pressure supplied to process is guaranteed with two stage pressure reduction, despite varying inlet pressure as cylinder get emptied from full pressure of 2000 PSIg down to pressures comparable to required outlet pressure.

0ur field experienced engineers can provide you dependable, cost effective right answers to difficult Hydrogen Unloading questions. Plus they provide after the sale commissioning support & service.

Different configurations are available, depending on available Hydrogen supply pressure, flow and controlled pressure requirements safety interlocks and degrees of instrumentation / remote - operation required.

About one hundred installations of Hydrogen Unloading Station all over India.

Tubing material, which has to be S.S. only,

Treatment given to the gas lining for thorough cleaning,

Type of fittings used for the working pressure range,

Material of construction to withstand the operating pressure,

Quality of the chemicals used for gas purification in terms of their physical & chemical properties, etc.


Apart from these, what is of utmost important is zero leakage of the system. We, at Onus Engineering, check the system thoroughly prior to its despatch from our factory, as well as installation at the site. This guarantees a long term trouble-free & satisfactory working of the system.

Cylinders Cascade & Gas Manifolds

We offer high quality Cylinders Cascade. A group of gas cylinders are interconnected by high pressure piping to form a single gas storage unit and are called a cascade. The cylinder cascade may contain from 6 to 600 gas cylinders.Widely used in various industries such as automotive, the primal benefit of the product is that it avoids individual handling of cylinders and adequate gas quantity resulting in better production planning and cost savings to the user.


Gas Manifolds:

We offer qualitative gas manifolds that are used to connect two or more high pressure cylinders together to achieve high flow rates or extra storage capacity. The products may be arranged in different configurations depending on flor space availability.

Gas Regulator

We are engaged in manufacturing a wide range of Gas Regulators which play an important role in our daily operations of gas chromatographs. Our company supplies various types of single stage and double stage regulators with indigenous, imported gauges in Brass, S.S. body with S.S. diaphragms. Gas regulators offered by us are leak proof and indicate correct pressure & are smooth in operation

Multi Cylinder Connection System

Our range of Multi Cylinder Connection System is renowned for its trouble free performance and long working life features. These are essentially a modified version of manifold system where more than 2 cylinders are required to be used with one instrument. Our range can be used all at a time or one at a time by only opening & closing a valve which in turns simplifies the operation & in turn also improves the life of the regulators.

Pressure Reducing System

Our organization is engaged in manufacturing and supplying a wide range of pressure reducing system also known as hydrogen unloading / pressure reducing stations, which are ideal for specific process requirement, right from pigtail and manifold to connect cylinders / truck trolley, auto manifold change over pressure reducing station, safety shut off, safety interlocks and flow measurement supplied as complete skid mounted ready to use unit. These pressure reducing systems are supplied for flows as high as 4000 nm³/hr and are known for its simple design and easy to maintain components. These onus manufactured hydrogen stations are the safest method of hydrogen consumption as it has built - in safety shut off arrangement with 100% redundant safety measures. We can also provide additional safety interlocks as per process requirements and also provide provision of nitrogen purging for safe operation. We have done about one hundred installations of hydrogen unloading station all over india and we also offer after sale commissioning support & service.

Advantages of our pressure reducing systems:

  • Ensures fast and maximum possible emptying of hydrogen cylinders.
  • Reduced batch time and no. Of cylinders change over compared to other means of hydrogen unloading.
  • No electrical or pneumatic supply is required to ensure normal working and safety shut-off operation.
  • High accuracy in control of final outlet pressure supplied to process is guaranteed.
  • Different configurations are available, depending on available hydrogen supply pressure, flow and controlled pressure requirements safety interlocks and degrees of instrumentation / remote - operation required.
Thus, one has to consider the genuinity of the materials used in the fabrication of the system, such as:
  • Tubing material, which has to be S. S. only.
  • Treatment given to the gas lining for thorough cleaning.
  • Type of fittings used for the working pressure range.
  • Material of construction to withstand the operating pressure.
  • Quality of the chemicals used for gas purification in terms of their physical & chemical properties.
  • Apart from these, what is of utmost important is zero leakage of the system.

Pressure Reduction Station

Pressure Reduction Station is most popular for pressure reduction in all types of industries.
Salient Features:

  • Maintains constant pressure irrespective of demand variations
  • Noise reduction
  • Remote setting
  • Offsets due to mech. friction & gland tightening are taken care by the positioner

Safety Relief Valve

Our safety relief valve is fitted in vessels to prevent an undue rise in pressure. Whenever the vacuum is build, the safety relief valve gets actuated and there is a rapid opening or pop up action to release the pressure. Used in various industries, our safety valve is available in sizes to suit the requirements of our clients.
