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.

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

High efficiency Silica gel & Molecular sieves are used for the purpose of removing moisture from the carrier gas. Silica gel is of indicating type changing its colour from blue to pink on use, having high moisture capacity. Molecular sieves are of spherical shape, yielding high mechanical strength & low dusting. Both the materials are of regenerable type.

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

The accidental ignition of flammable gases or vapors from vent pipes of storage tank or process vessel presents a constant threat to plant and personnel. The use of flame arresters is one of the essential measures taken to avoid or minimize the possible consequences. Their application is widespread, ranging from the protection of small solvent tanks to the safety of large and complex process plant. The oil, gas, petroleum, chemical and petrochemical industries are major users. A flame arrester is a static device which stops a flame entering into the storage tank or process vessel containing a flammable gas or vapor. An end-of-line type flame arrester is fitted at the extreme downstream end of a pipeline. The arrester consists of a flame quenching, element contained within a housing which incorporates thread or flange connections for fitting to pipework. The element is often of greater diameter than the pipework in order to compensate for pressure drop and therefore the housing is enlarged accordingly. 

e 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.

Onus Offers Skid Mounted ready to use, continuous inertisation (Blanketing & Purging) systems for safe operation of centrifuges. Salient features are: Ensures presence of N2 in the Basket and Bearing Housing & ML Tank Reduce oxygen content in the Basket & Bearing Housing and eliminates the possibility of hazard / fire Completely Self actuated system without auxiliary power with lower & over pressure indication / alarm Low set point technology results in very low nitrogen consumption Available in Automated & Manual Option

These are useful as relief valves for blanketed vessels in which solvents are filled & drawn out at a high flow rate. These can also be fitted, on the process vessels to safeguard the process equipment where unpredicted fluctuations in pressure may occur. By retaining toxic vapors and avoiding atmospheric contamination these help to provide increased fire protection and safety. Pressure cum vacuum relief / breather valves are designed to protect your tanks from possible casualty due to over pressure created by thermal expansion & product movement into the tank and excessive vacuum created by thermal contraction & product movement out of the tank. At the same time it minimizes costly product evaporation / loss. Continued design improvements provide these valves with high efficiency, maximum flow capacity and minimum leakage. These are available "closed end hoods" type of standard design or with "pipe-away design" for vapor recovery. These can also be offered as only the vacuum relief valves with blind flange on pressure port and vice versa. 

Tank blanketing & tank protection devices complying Some of the salient features are as follows: Simple, easy to maintain and reliable design Turnkey solutions for blanketing system with safety devices along with nitrogen high pressure reducing station for storage tanks, reactors & centrifuges Low-set point technology ensures very low nitrogen consumption & operating cost Extensive material selection compatible to different solvents High system accuracy where extremely low set points and minimal proportional bands are important Low flow purging systems for safe operation of centrifuge

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

Downstream Pressure Control Valves are pressure reducing valves which combine sensitivity with stability of the controlled pressure. These valves can react to very small changes in controlled pressure. Due to the pressure loaded design, differential pressure across the main valve diaphragm is minimum. Hence these valves are also suitable for high pressure setting. Main valve actuators are available to cover wide range of pressure and flow requirements. Features: Accuracy Easy to Maintain High Capacity Pressure Control Economical Labor Saving Installation Tight Shut off Capability
