Engineering & Design
Six full-time engineers. 3D modeling, classification submissions, back-pressure analysis, sound attenuation.
ExploreSeaClean® — kill the soot. Keep the clean hull.
SeaClean is our patented marine diesel particulate filter (DPF). It captures up to 98% of generator soot and unburned hydrocarbons — eliminating hull staining, diesel odor, and oily slicks. The only DPF on the market with variable pre-heater technology for true active regeneration across the full load range.
- 98% particulate capture
- Variable pre-heater — true active regeneration
- Modular: fits inside the generator sound shield
- Class-approved with ABS, Lloyd's, DNV, RINA
- Acts as a load bank at low generator loads




Built to a higher standard — for vessels that don't fail
Every component carries a job number for full traceability. Every weld is hand-performed by AWS-certified TIG fabricators. Every system can be classed by every major maritime society.
Aircraft-quality TIG welds
Hand-welded by American Welding Society certified fabricators. Argon-protected from a 1,625-gallon on-site tank.
Class-approved
ABS, Lloyd's, DNV, RINA, ABYC compliant. Drawings and specifications submitted before fabrication.
316L · Inconel · AL6XN
Premium alloys with passivation in nitric acid for restored corrosion resistance. Die-formed elbows in tube size — not pipe.
Four mobile service teams
From troubleshooting and emergency repair to commissioning new builds, our service teams travel worldwide.
30,000 sq ft, all in-house
Engineering, fabrication, parts, and service under one roof in Fort Lauderdale. Walk-up parts counter.
Worldwide reach
From Carolina sportfish to supply vessels in Dubai — we install and service everywhere our customers operate.
Captains, engineers & owners — on record
"Once again I find myself truly appreciating the work of DeAngelo Marine Exhaust. Pairing their fabrication and installation with the SeaClean System gives you a solid performer that really outshines any other work I've come across. Full credit to DeAngelo — never once did they say 'no, it can't be done.'"
"I am the bringer of good news today. Our owner could not stop raving about the good job done. He asked whether I had routed the generator exhaust from the transom because he could hear the genny running but see no telltale slick. It is a huge leap forward — bust the 2000-hour milestone with no back-pressure problems in sight."
"I've struggled with poor exhaust system design and emissions throughout my career. The SeaClean system has been in operation for months and all the smoke, soot, and waterborne slicks are gone. Your crew thinks clean exhaust emissions are normal — and very honestly they should be."
