Retrofitting any air dampers is always possible and doesn't have to mean a huge amount of work on either the vessel or engine room. 

This Netherlands based client recently inquired to have supplied a set of A-60 Stainless Steel Dampers to retrofit an in-service defence vessel. Military applications are becoming a large part of our product exports and we will work hand in hand with you on not just new vessel construction, but also should you require larger or better performing engine room ventilation to be installed in a currently operating boat. 

This vessel required a new set of air dampers and fans in response to larger power plant (specifically new generators) being fitted. The increased genset size was causing an uptake in heat load and along with new A-60 air dampers, they also needed additional engine room fans to be installed. The new A60 Stainless Steel Air Dampers allow the addition of extra air flow to counteract the heat load increase.

These SS Dampers are fitted with round duct adapters to allow additional ducting to be branched to the required location.

NB: Please be aware that we are experiencing extended lead times due to a challenge obtaining some of the components for these dampers. It could be as much as 6-8 weeks supply time at present.
