High Performance Fans Make a Splash in Marine Market
High performance fans designed for extreme environments in sectors including bus & coach and racing, are proving a hit with boat owners and boat builders, who are using them in engine room ventilation systems.
The fans, which are manufactured by SPAL Automotive, have a formidable reputation for reliability and long-life under the most challenging conditions, which makes them ideal in a marine environment.
Required to maintain air quality in the engine room and keep the area cool so that the engine does not need to work overtime, the fans also serve an important filtering role to keep salt laden air out of the engine room. Accordingly, owners and builders alike are specifying components of varying sizes which can be adapted to an existing design or even have a system designed around them.
Andy Clift at SPAL says: “We’ve known for a few years the reliability of a SPAL fan is favoured by some extreme markets and the marine world is no exception. Recently we’ve seen an increase in aftermarket requests for SPAL fans for servicing and replacement parts for engine room ventilation and talking to more boat designers & builders about their requirements.”
Veotec Case Study – SPAL Fan Application Veotec Ltd, known for design and manufacture of bespoke Gas turbine air intake equipment, was approached by a number of boat builders to design a new air intake and exhaust system for wind farm service vessels. Problems faced by all vessels whilst operating offshore include how to stop water and salt ingress into the engine bay whilst maintaining sufficient through air flow for efficient combustion and cooling. Fitting a fan which can cope with these conditions was essential and SPAL provided the solution. Using CFD analysis of airflows based on engine HP and Hull design, Veotec has designed a range of air intake and exhaust systems which allow sufficient airflow for efficient combustion and cooling whilst removing salt and water from the air.
Using a modular system, Veotec units feature patented filtration technology combined with innovative self-closing damper and fan unit to provide an all-in-one solution which meets the airflow requirements for a wide variety of vessels.
