E-3 Series Boiler Feed
The E-3 Series vacuum boiler feed units pump condensate and makeup water directly into the boiler(s) using various pressures and flows specifically tailored to boiler specifications. This vacuum unit comes with an accumulator tank and a top-mounted hurling tank. Pumping action is determined by a boiler-mounted level controller that senses boiler water level requirements.
Vent-Rite offers standard float-operated makeup valves or special electric solenoid valves on tanks designed to replenish water inside the boiler feed unit when water levels get too low. Vacuum pumps circulate water to and from the hurling tank. As water and air pass through a jet-type exhauster, it creates a powerful vacuum that helps remove air from the system, allowing steam to travel longer runs and providing quicker warm-up times.
