The Meaning of Hydroluft: Water, Air and the Separation of Fluids

Our name is made of two words. Hydro, from the Greek for water, and Luft, the German word for air. Together they describe the two great families of fluids, liquids and gases, and the work we have done since 1993: separating what should not be mixed.

Everything fluid

In engineering, a fluid is anything that flows. Water, oil, fuel, coolant, effluent, compressed air, nitrogen and hydrogen are all fluids. In almost every industrial process a fluid carries something it should not: oil in water, water in oil, dirt in a lubricant, moisture or particles in a gas. Taking those contaminants out, reliably and at the right cost, is what Vens equipment is for.

The Hydro side: liquids

• Oil from water: belt, tube, disc, drum, rope mop and floating skimmers, which lift floating oil off the surface.

• Oil water separators: API, TPI and CPI separators, coalescers and hydrocyclones for oil carried through the water.

• Oil spill response: booms, skimmers and power packs that recover oil from rivers, harbours and the sea.

• Liquid filtration: cartridge and bag filters, simplex and duplex filter housings for lubricants, fuels, process liquids and water.

• Tank equipment: floating suction units that draw clean product from the top of a storage tank, away from water and sediment at the bottom.

• Wastewater: screens, gates, scrapers and decanters for treatment plants.

The Luft side: air and gases

• Air filtration: filters tested to ASHRAE 52.2, EN 779, EN 1822 and ISO 16890 for clean air in plants and buildings.

• Gas filtration: high pressure purge filter housings rated up to 320 bar.

• Gas systems: HP fill and purge assemblies that handle hydrogen and carbon dioxide for hydrogen-cooled power generators.

Where the two meet

Some of the best separation happens where air and water work together. In dissolved air flotation, fine air bubbles attach to oil droplets and suspended solids and float them to the surface, where a skimmer removes them. Water, air and separation, in a single process: Hydroluft in one machine.

Vacuum recovery systems use the same idea in reverse. Air flow lifts oil and sludge from pits and spill sites into a tank.

What the name commits us to

A name that covers every fluid is a promise to understand the process, not only to supply the part. We look at the fluid, the contaminant, the temperature, the pressure and the site before we recommend a product. Then we design, build and support it for the life of the installation. That approach has taken Vens equipment into more than 10,000 installations in refineries, power plants, steel mills, food plants, ports and treatment works around the world.

Whatever is flowing through your plant, tell us what needs separating. Our engineers will recommend the right equipment.
