Booster ad alta e media pressione per gas tecnici

Application Natural gas represents one of the most efficient, economical, environmentally friendly and abundant fuels nationwide. Its complete compatibility with current engines makes it a viable alternative to traditional vehicle fuel. Manufacturers are increasingly developing a range of vehicles designed to run cleanly and efficiently on natural gas. In addition, simply converting some existing vehicles with a switch to switch between natural gas and gasoline (bi-fuel) does not compromise performance, making the power output of the two fuels virtually indistinguishable. One of the strengths...

A profoundly Italian company, Coltri began building high-pressure scuba diving compressors in 1963. The company soon expanded into other fields, including firefighting compressors and industrial gas compressors. Today we are once again looking in a new direction. Ongoing advances in design and manufacture are at the very core of our identity: more than fifty years of continuous development have enabled us to engineer equipment that now sets the benchmark for the industry worldwide. Our commitment to research and development has enabled us to shift from consuming the latest technology to becoming...
