Overview
Equimeter’s large capacity industrial service regulators are designed and built for commercial,
industrial, and gas distribution use. As a result of the union connection between the fully interchangeable bodies and the diaphragm case, they have remarkable field versatility. They are
easy to install, adjust, inspect, and service in all piping arrangements.
Applications
Equimeter’s family of large capacity industrial service regulators can be used in a variety of
applications such as: factories, foundries, district regulator stations, commercial laundries, hotels, motels, bakeries, schools, hospital, churches, etc. They are designed for use on all types of
gas fueled equipment including boilers, burners, furnaces, ovens, heaters, kilns, engines, air
conditioners, etc. Although mainly used with natural gas, they perform as well when used with
LPG vapor, air, dry CO2, nitrogen, and other inert gases. Please contact your Equimeter representative for information on special construction which may be available for certain corrosive
gases.
Operating temperatures range from -20° F to 150° F. Equimeter 243 regulators are not recommended for buried service.
