Water Injected Screw Compressors The Most Economic Option For Genuine 100% Oil-Free Air

There is no doubt that food and drink industry processes require compressed air that is guaranteed to be totally pure, with no possibility of oil carry-over to contaminate the product. (Read More)

Filters and catalytic convertors will always have an element of risk and the only safe option is a genuine oil-free machine.

There are two alternative technologies available – the dry-screw (adiabatic) and the water-injected screw (isothermal). But the former has disadvantages in both capital outlay and, more importantly, in running costs. Heat generated in compression means loss of efficiency to generate the correct volumes of air needed – meaning less air delivery per kW used.
Thanks to the superior cooling capability of water, the Worthington Creyssensac  WIS range removes the heat efficiently at source meaning that more air per kW is generated and electricity costs are cut substantially.
The WIS compressors have polymer ceramic rotors and water lubricated bearings, ensuring that no oil contaminates the element. The resultant air is classified Class “0” – ISO8573-1. The zero indicates absolutely no oil carry-over.

20% efficiency increase

The largest cost in owning and operating a compressor is in the electricity used to power it – well over 70% of the lifetime costs. Any reduction which can be achieved in usage here can be significant and the Water-injected Screw shows that  around 20% less power is needed to generate similar volumes of air, because of the constant temperature in the compression chamber.
There are also savings in wear and maintenance. The  aluminium bronze element housing gives added strength and durability and the hydrodynamic bearings ensure long life and smooth rotation with no physical contact in the bearing itself. A direct drive motor also reduces bearing stress and energy loss. Reverse osmosis ensures a constant supply of high quality water, avoiding corrosion and bacteria growth. Service is only required every 4000 running hours.

With pressure options from 7.5 to 13 bar and further energy savings of up to 35% to be made with optional fully integrated inverter drive technology, the WIS range is backed by Worthington Creyssensac’s 145 years of experience and a nationwide specialist distributor network for all installation and maintenance.
