John Deere Power Systems is pleased to announce a new patented PowerTech HazLoc diesel engines. Built upon John Deere's proven 8.1L platform, the PowerTech HazLoc 6081HFH75 diesel engine received United States Coast Guard, Marine Safety Center certification for Class 1, Division 1 (Zone 1) Groups C & D hazardous locations. The PowerTech HazLoc electronically governed diesel engines are certified for use on board USCG–certified subchapter D & O vessels. As electronic engines have become more commonplace, engines installed in these marine applications are required to meet Class 1, Division 1 (Zone 1) weather-deck requirements for electronics as directed by the USCG in United States-flagged vessels where there is the possibility of an explosive atmosphere in normal operations. A Class 1, Division 1 (Zone 1) area is defined as being within a 3-meter (10-foot) radius of any source of gases that could create an explosive atmosphere, including tank vents, sounding tubes, valves and pumps. Any engine that operates in these conditions must meet these requirements. John Deere is the first diesel engine manufacturer to receive USCG MSC certification for Class 1 Division 1 (Zone 1) group C & D hazardous weather-deck locations, for electronically controlled engines. The new PowerTech 6081AFH75 also has 8.1L of displacement and offers up to 280kW or 375hp at 2400 rpm. It is a 6-cylinder, electronically controlled engine with an air-to-coolant aftercooler and a water-cooled exhaust for use in marine auxiliary applications.
