Marine environments can be particularly harsh due to the high salt content; standard aluminium products can quickly corrode so stainless steel is generally preferred.
The issue with stainless steel casings are firstly, weight and secondly cost. To combat this, Silent Sentinel offer an optional special marine grade paint finish on all of its product range. The product is called XYLAN.
XYLAN coatings offer many benefits including resistance to corrosion and chemical attack and have been used in the offshore industry for over 30 years.
