Profile: The Kahn Companies is a provider of pneumatic, hydraulic and electronic equipment. We are an ISO 9001 certified company. Our dynamometers are ideal for load testing of medium speed turboshaft engines, light turboprop engines, auxiliary power units, engine power takeoffs, aircraft accessory gearboxes and helicopter transmissions. Our hydraulic dynamometers use water as a medium for absorbing and measuring the power output of engines, turbines and electric motors & they are used in applications such as aerospace, automotive and power generation applications. Our hygrometers are used to measure the dew-point at the outlet of desiccant and refrigerated air and gas dryers to insure the air is correctly conditioned. Our series 100 hydraulic dynamometers features cavitation- and corrosion-resistant stainless steel power elements & a self-centering polygon connection between shaft and rotor discs that permits quick, on-site overhaul by eliminating hydraulic & heat shrink fits. We offer a wide range of air dehydrators for navy surface ship and submarine applications.
