\n\tLinde LLC, Bridgewater, N.J., has developed a protective-atmosphere safety monitoring system that can be installed on new or existing nitrogen supply systems for all common types of heat treatment furnaces, and can be tailored to the unique needs of the operation.<\/p>\n
\n\tThe system helps companies operating heat treatment furnaces to improve safety by installing a protective-atmosphere monitoring system in compliance with the National Fire Protection Association’s “Standard for Ovens and Furnaces” (NFPA 86).<\/span><\/p>\n \n\tHeat treating furnaces depend on a nitrogen supply to help operators initiate a safety purge with inert gas of the flammable atmosphere, and NFPA 86 requires proper monitoring and controls to reduce fire and explosion hazards.<\/p>\n \n\tThe Linde safety solution is designed to monitor nitrogen supply levels, and it signals operators at low conditions with an audible alarm and strobe. To help ensure availability of supply for the flammable-atmosphere nitrogen purge, the integral alarm panel provides indicators for low liquid-nitrogen level, low nitrogen pressure, and low nitrogen-supply temperature.<\/p>\n \n\tThe Linde furnace safety solution can be installed on new or existing nitrogen supply systems for all common types of heat treatment furnaces, and can be tailored to the unique needs of the operation. Safety monitoring systems are a standard part of Linde heat treatment technology upgrades.<\/p>\n
