Description
The Mepco (Dunham Bush) 44-2125 is a Float & Thermostatic (F&T) high-pressure steam trap featuring a 3/4″ connection in an “H” pattern (inline) body configuration. Designed for demanding commercial and industrial steam heating systems, this trap continuously discharges condensate while venting non-condensable gases — maximizing system efficiency and protecting downstream equipment.
Product Overview
Float & Thermostatic steam traps combine two mechanisms in a single body: a float valve that responds to condensate levels for continuous, modulating discharge, and a thermostatic air vent that automatically purges air and non-condensable gases at startup and during operation. The result is a trap that handles varying condensate loads with precision while keeping steam losses to a minimum.
Key Features
- Float & Thermostatic (F&T) operating principle for continuous condensate discharge
- High-pressure (HP) rated design suitable for demanding steam system applications
- 3/4″ connection size for standard steam distribution piping
- “H” pattern (inline/horizontal) body orientation for straightforward in-line installation
- Integrated thermostatic air vent for automatic purging of non-condensable gases
- Durable construction engineered to Mepco (Dunham Bush) quality standards
- Designed for reliable, long-service-life performance in commercial and industrial steam systems
Typical Applications
- Steam heating coils and heat exchangers
- Unit heaters and cabinet heaters
- Steam distribution mains and branch lines
- Process steam equipment requiring continuous condensate removal
- Drip stations on high-pressure steam mains
Why Choose an F&T Steam Trap?
Unlike thermodynamic or thermostatic-only traps, the Float & Thermostatic design discharges condensate continuously as it forms — preventing waterlogging, reducing water hammer risk, and maintaining consistent heat transfer rates. The built-in thermostatic air vent ensures rapid system startup and eliminates air binding.
