No hotter than 220 degrees Celsius!
Frenzelit develops new thermal insulation board solution for marine engines
Isotherm 800 CG can be precisely machined to size based on customer CAD specifications. © Frenzelit(firmenpresse) - Frenzelit’s latest thermal insulation innovation: Frenzelit has developed its Isotherm 800 CG insulation boards especially for encapsulating exhaust components in marine engines. The insulation boards are manufactured using a needlemat process. The boards interlock precisely to ensure that the legally required temperature limits for exhaust pipes are not exceeded, thereby preventing any media that escapes, such as diesel fuel, oil or hydraulic fluids from igniting on hot surfaces in the event of leakage.
The globally binding SOLAS220 (International Convention for the Safety of Life at Sea) regulation has been in force for the thermal insulation of engines on large container and cargo ships as well as cruise liners since 2014. The convention states that engine room surfaces must not exceed 220 degrees Celsius to reduce the risk of any escaping liquids from igniting. Many diesel-driven engines will need to be retrofitted and thermally insulated in order to meet these requirements.
Insulation boards that interlock precisely based on CAD specifications
Frenzelit – the specialist for gaskets, technical textiles and high-temperature-resistant insulation – manufactures insulation boards for these retrofit projects using a special needlemat process. First, a fiber blend is used to create nonwoven fabric with a high density, which undergoes a pressing process to convert it into a board that can be precisely machined to size. Until now, only somewhat adaptable acoustic pillows were used for thermally insulating engine room heat zones. But these pillows could never be optimally adapted, they formed cavities inside the engine housing and were unable to withstand the powerful vibrations and heavy loads for long periods. Sebastian Kühn, Key Account Manager at Frenzelit, explains the advantages of insulation boards compared to the pillow-based variant: “Our boards are manufactured and mechanically adapted exactly according to our customers’ CAD specifications. They can then be installed in the customers’ metal frames like the pieces of a puzzle. This greatly minimizes risk during installation because everything fits together precisely and the individual metal frame is used to build a fully closed, encapsulated system.” All of the materials Frenzelit uses in shipbuilding meet Marine Equipment Directive 2014/90/EU Module D guidelines.
Long fibers for high mechanical resistance
The new technical solution underwent 3,000 hours of continuous customer-side testing without incurring any damage. The extreme vibration resistance comes from the length of the insulation board fibers – ranging from 40 to 80 mm. The customer also appreciates its easy handling thanks to the low weight, uniformity and simple installation even in tight engine room spaces. Quick retrofit times ultimately also lead to major savings because they allow marine vessels to quickly return to full operation.
