Profile: The John M. Ellsworth Company, Inc. distributes fuel transfer pumps and fueling equipment. Aircraft fueling equipment includes aircraft fueling hose & fueling nozzle, deadman system and grounding equipment. Reelcraft grounding reels are used to ground equipment operating in hazardous atmospheres, such as fuel trucks or carts transferring flammable materials. When properly clamped to the ground, the static discharge reels dissipates static electrical build up and reduces the chance of sparking & the potential for explosion. Water sprinkler system gauge is designed for the fire sprinkler industry. Sprinkler line tester is the last sprinkler head on system branch lines, controls water flow for flushing or testing of the system. When the wet pipe sprinkler system operates, the water flow in the pipes is at a relatively low velocity. Friction loss increases with the age of the sprinkler piping, up to 100 percent after 15 years. The accumulation of sediment and foreign objects in spinkler systems can be prevented by flushing the supply mains to the systems through the hydrants at least semiannually.
