Modular Dry Exhaust

At Delta T Systems, we believe that a vessel’s dry exhaust system should be cost effective, light-weight and simple to install with a clean professional appearance.

The DINAK GE dry exhaust system features thin wall stainless steel modular components, which are insulated and designed for the exhaust of combustion gases. Never before has it been so easy to design and install a quality dry stack exhaust system on board a vessel. This aesthetically pleasing and cost effective exhaust system solution may be easily installed by boat builders or ret yards without any special tools or training and produces a highly efficient exhaust system with a long life span and superior performance.
