Air vents and air eliminators

Air and other non-condensable gases cause long warm-up times, lower steam temperature at a given pressure, reduce heat transfer and accelerate corrosion across steam systems. Where the trap itself cannot vent air quickly enough or the steam space geometry creates dead spots, a separate air vent can be used to remove accumulated gases before they damage process performance. Spirax Sarco automatic air vents and air eliminators remove those gases without wasting live steam, helping systems heat up faster and operate more efficiently during start-up and normal running. The range includes vents for steam systems, liquid systems and clean steam duties, so the venting method can be matched to the fluid, cleanliness requirement and installation location. Correct venting strategy helps prevent the hidden losses associated with air binding, poor condensate drainage, unstable temperature control and gas pockets that sit beyond the reach of a standard drainage point. That makes separate venting especially relevant on separators, steam mains, process vessels and other locations where air release cannot be left to condensate drainage hardware alone.
