MSHA recognition for Nett particulate filters

摘要

Nett Technologies Inc. announces the authoritative recognition by the U.S. Mine Safety and Health Administration (MSHA) for its diesel particulate filter (DPF) technology. This technology is pivotal in assisting retrofit compliance with the newly adopted MSHA rules regarding diesel particulate matter (DPM) emissions in underground mines. It is the first legislation to control miners' exposure to diesel particulates in US mines. The coal mine rule prohibits heavy duty diesel equipment to emit levels exceeding 2.5 grams per hour of DPM will a phase-in schedule beginning May 21, 2001. Thousands of diesel engines in underground mines will be retrofitted with diesel particulate filters to comply with these regulations. Two Nett_ particulate filter technologies; cordierite, which performs in most heavy-duty applications with high exhaust temperature, accommodating engines from 15 kW to 450 kW in a single exhaust configuration; SiC (silicon carbide) has higher maximum operating temperature limits, accommodating engines from 13 kw to 206 kW in a single exhaust configuration, comply with the new MSHA diesel regulation for coal and metalon-metal underground mines.
