More pressure-resistant, more temperature- and ozone-resistant, more abrasion-resistant, more flexible - hose assemblies of the Exovation product line exceed the standard requirements
Standards are important and necessary because they define a uniform quality standard for hose assemblies. But if the hose in the machine then actually only meets the minimum requirements, in many cases this is not only annoying but also cost-intensive: machine stop, new material, assembly ...
With the claim "The better the hose properties, the lower the risk that the hose assembly will fail prematurely", Interhydraulik has launched a product line whose properties clearly exceed the standard requirements. Thanks to improved hose covers and designs, Exovation® hoses are – depending on the type – more pressure-resistant, abrasion-resistant, flexible, ozone-resistant or temperature-resistant. In detail, this means:
Only between 0.01 and 0.5 g abrasion
The principle is simply explained: mechanical stress on the hose cover leads to abrasion. The higher the abrasion, the shorter the service life of the hose.
The European hose standards (EN853, EN854, EN856, EN857) prescribe maximum abrasion values of between 0.5 and 1.0 g for braided and spiral hoses. By comparison, hose assemblies in the Exovation® product line have a maximum abrasion of 0.5 g throughout. Hose types with the suffix "G" are designed for demanding applications and have a maximum of 0.2 g abrasion. For applications in extreme environments, Interhydraulik offers hose types with the suffix "Z". These have abrasion values of max. 0.01 g.
Between 150 and 3,500 h* ozone resistance
The hose lines of the Exovation® product line are also impressive in terms of their ozone resistance. All lines have twice the ozone resistance (150 h) of the standard requirement (72 h). Hose types with the suffix "G" achieve 400 h ozone resistance, hose types with the suffix "Z" even 3,500 h*.
Bending radii up to 38% more compact
The hose lines of the Exovation® product line feature more compact bending radii at higher operating pressures. They undercut the bending radii of comparable hose standards by up to 38 %.
Up to 1,000 h corrosion resistance
Fittings and in particular the deformed hose sockets are susceptible to corrosion. Common zinc coatings based on chromium VI/chromium III or zinc-nickel do not always meet customer requirements of 500-1,000 h corrosion resistance.
Interhydraulik offers zinc-nickel coatings and also nickel-free surfaces that achieve 1,000 h corrosion resistance. So the risk of hose failure due to corrosion is significantly reduced with Exovation®.
By the way, you can recognize an Exovation® hose not only by the corresponding lettering on the layline, but also by the fact that there is an additional marking behind the hose type (in our example, the 2SC): the A. In this case, the A indicates that the hose has an ozone resistance of 150 h and a bending radius that is 5% smaller than comparable hose standards.
