Hoffman 404339 - Model B1125B-3 Inverted Bucket Steam Trap with Strainer, 3/4"

Reliable condensate drainage is essential for maintaining optimal thermal efficiency in industrial heating systems and HVAC process equipment. The Hoffman 404339, model B1125B-3, serves as a high-performance 3/4-inch inverted bucket steam trap designed to manage condensate discharge while preventing steam loss. This unit features an integrated strainer and thermic vent, ensuring long-term operational reliability by protecting internal components from debris and air binding.

The inverted bucket mechanism utilizes buoyancy to regulate flow. As condensate surrounds the bucket, the trap remains open to discharge liquid; when steam enters, the bucket becomes buoyant and rises, effectively closing the discharge valve at the top to retain steam until further condensate accumulation occurs. This simple yet robust design ensures consistent cycling under demanding load conditions.

Key System Performance Baselines:

• Energy Efficiency: Provides rapid condensate removal to prevent water hammer and heat transfer reduction.
• Integrated Protection: Features a built-in strainer to capture particulate matter, extending valve and seat service life.
• Air Handling: Incorporates a thermic vent to effectively clear non-condensable gases during system startup.
• Rugged Design: Built for demanding industrial environments requiring continuous-duty steam drainage.

⚠️ Application Profile: Designed for steam main drips, unit heaters, heat exchangers, and industrial process coils requiring robust inverted bucket steam trapping technology.
