Contamination control coatings

NSA is a thin, invisible coating applied on metal surfaces or on top of surface treatment. It considerably reduces the contamination of the fan. The coating has excellent wear-resistance properties, and it adheres well to both bare metals and painted surfaces. On a fan impeller, NSA significantly reduces imbalance caused by contamination. Imbalance often leads to unnecessary outages and premature bearing damage.

NSF is a fluoroplastic coating which adheres very well to metals. The coating considerably reduces contamination of the fan, and is very easy to clean. The coating also has excellent chemical and corrosion resistance. On fan impellers, NSF significantly reduces imbalance conditions caused by contamination and thus helps avoid unnecessary outages and premature bearing damage. It also reduces the time required for cleaning the impeller.

Wear-resistant coatings

WNS is a composite coating that combines the wear-resistance and contamination control properties of the WRP and NSF coatings. Hot-sprayed wear-resistant coating is covered by a baked fluoroplastic anti-contamination layer. The process produces a coating with excellent anti-contamination and wear-resistance properties.
WNS considerably reduces the contamination of the fan, and the underlying hard coating effectively protects the base material against wear. The coating is very easy to clean. The anti-contamination coating thus functions in an optimal manner at places where the particle velocity is low and particles might easily contaminate the surface.

On a fan impeller, WNS significantly reduces imbalance conditions caused by contamination and thus helps avoid unnecessary outages and premature bearing damage. It also reduces the time required for cleaning the impeller and prevents the wearing of the impeller and other fan components, which also often lead to unnecessary outages and premature repairs.

Wear- and abrasion-resistant coatings

WRT coatings are hot-sprayed onto the base metal, which produces a very hard coating that is resistant to wear and chemical corrosion.
The abrasion resistance properties of the WRT coating are considerably higher than those of regular wear-resistant and structural steel types, which means that the WRT coating is particularly well suited to abrasive and mildly corrosive environments.

On a fan impeller, WRT significantly reduces the wear of the impeller and other fan components, and the resulting unnecessary outages and premature repairs.

Abrasion-resistant plates for extreme conditions

Abrasion-resistant WRP plates are designed for extreme abrasion, erosion and corrosion conditions where the abrasion resistance of regular steel or even regular abrasion-resistant steel does not meet the need. The abrasion resistance of the plate is up to 60 times better than that of regular steel, and many times better than Hardox steel, for example. The plates also have excellent heat resistance properties.

Abrasion resistant plates lengthen the fan's operational life and significantly reduce the wearing of the impeller and other fan components, which could lead to unnecessary outages and premature repairs.
