Armstrong Stainless Steel Inverted Bucket Steam Traps

Armstrong Stainless Steel Inverted Bucket Steam Traps

Armstrong Inverted Bucket (IB) Steam Traps seal better, last years longer and outperform any other type of traps on the market today. Engineered for a longer, more efficient service life, IB Steam Traps continue to conserve energy, even in the presence of wear. With fewer costs for replacement parts, installation and downtime, the long-term savings and value can be dramatic. For best practice energy management, Armstrong IB Steam Traps are the most effective choice.

No Wasted Steam

With Armstrong IB Steam Traps, there is no energy loss due to wasted steam. Any steam that passes through the bucket vent will be condensed into the surrounding liquid. Steam cannot get into the top of the trap and/or be pushed downstream of the trap through the orifice. By eliminating the needless expense of wasted steam and energy, the IB Steam Trap provides a substantial savings in operating costs.

Guaranteed TO PERFORM

Our Stainless Steel Inverted Bucket Steam Trap and Stainless Steel Trap Valve Station are both backed by Armstrong’s three-year guarantee; however, when used in combination, Armstrong offers a five-year no-leak guarantee.

More About IB Steam Traps from Armstrong University

Bucket vent sizing is based on the ability to pass typical volumes of non-condensable gases (air) encountered, while minimizing potential steam flow through it. This allows radiation losses of the trap body and cooler condensate prime to condense it. Volumes vary with pressure and radiant heat losses vary with body mass and ambient conditions. However, this small volume of steam (live or flash) is vented into the liquid seal surrounding the bucket (which has lost all latent heat), so it is typically condensed.

The orifice remains closed and surrounded by condensate until the condensate level inside the bucket reaches the point where the bucket loses buoyancy and discharges. The condensate level inside the bucket is independent of the constant level outside the bucket over the orifice where vented gases are accumulated; this further minimizes the loss of any condensable gases (steam) through discharge. The energy efficiency of this design and its ability to prevent loss of live steam has been documented and tested.
