Dipesh offers well-engineered andwide range of Pressure Vessels for various Gas-Liquid storage.

Dipesh understands processs heat transfer, thermal andflow engineering. We put our knowledge to design andmanufacture Shell & Tube Heat Exchangers, Double Pipe, HairPin, Finned Type, Silicon Carbide Heat Exchangers, TitaniumHeat Exchangers etc. that deliver.

Our equipment have stood for decades with unbeatable andlasting performance.

At Dipesh Engineering Works, we specialize in designing and supplying coded Hydrogenators with highly efficient impellers and overall agitators for gas liquid reactions in aggressive services.

Our impellers are ideal for reaction such as:

Hydrogenation, Oxidation, Ethoxylation, Phosgenation, Chlorination, Ammonolusis, Carbonation, Bromination, Sulphonation&Fluorination.

Advantages:

• Through our designs, we ensure that during rotation of the impeller, a vacuum is created at the tip due to venturi action. This vacuum overcomes the liquid heat. Fresh or unreacted gases from the vessel upper crest re-circulate into the liquid/slurry through the hollow shaft.
• Higher gas flow rates and finer bubbles sizes impart a very high gas-liquid interfacial area. A unique flow pattern provides desired movement of the catalyst and excellent contact of the gases with the catalyst or solids
