The Vernatone™ exhaust muffler is the original FRP water-cooled marine muffler. This style has been used by boat builders and boaters world wide for over 40 years. The Vernatone family of inline mufflers includes eight basic products with hundreds of variations in length, width, height, inlets and outlets. Builders and boaters requested these variations for specific engine or location requirements in a particular vessel. These mufflers also vary in size which influences the acoustical performance.
The Vernalift muffler was designed originally for small auxiliary propulsion engines installed near or below the water line in sailboats. In the early 70’s the quieting capabilities of lift mufflers were recognized. The Vernalift family expanded to include new and larger engines.
This new exhaust silencer was designed specifically for use with underwater exhaust systems. It combines Centek’s experience in muffler design with all the benefits of an underwater discharge. One of the benefits includes the elimination of the exhaust gases flowing back into the boat, commonly referred to as the “station wagon affect”. Another benefit is the elimination of engine exhaust deposits (soot) staining the exterior surfaces of the boat. The underwater exhaust is available in a vertical design for installation in the engine room as well as a horizontal design for mounting under the deck in the cockpit area.
This muffler design simplifies the conversion to underwater exhaust by combining the main engine exhaust and bypass line in one simple package. This muffler will greatly reduce the chance of vibrations associated with other underwater systems.
Like all Centek products, this muffler is available in many shapes and sizes and can be custom built to fit any environment or engine. Contact Centek Engineering for specifics on custom designs.
GAS/WATER SEPARATION MUFFLERS
The routing of exhaust gas and cooling water in some complex vessels brought about the development of new types of muffler products. Centek has met these needs with its gas/water separation mufflers. Separation systems are very effective where engines are located amidships or well forward in the hull and extremely effective in reducing exhaust noise.
The Gen-Sep™ is used in conjunction with a Vernalift muffler on generator sets. The water drain from the Gen-Sep™ can be located below the water line to eliminate irritating water splash during overnight moorings.
The patented COMBO-SEP™ combines a Vernalift muffler and a highly efficient gas/water separator into a single space saving unit. The COMBO-SEP™ is excellent for mid-range generators and propulsion engines installed at amidships or forward. Centek recommends the COMBO-SEP™ for above water line installations for maximum silencing and excellent water separation.
VERNATUBE™ is a resin-impregnated glass filament wound tubing wound exclusively with a fire retardant resin formulated for high temperature applications. Centek uses the fire retardant VERNATUBE™ to fabricate many of the basic components used to manufacture our wet marine exhaust systems. VERNATUBE™ exceeds values for the class of materials designated as “self-extinguishing” per ASTM –D-635, UL94V-O, and the US Navy/USCG MIL-R-21607 and MIL-R-7575. The smooth, resin-rich I.D. assures minimal restriction to exhaust gases and cooling water flowing through the tubing. Precise control of the outside diameter ensures ease of connecting mating ports with marine exhaust hose.
Exhaust systems fittings are made of the same fiberglass and fire retardant resins used to produce Vernatube, our UL listed tubing line. The fittings are lightweight, strong, non-corroding, and durable. Fittings are easy to install and O.D.’s are compatible with approved marine rubber exhaust hose.
