The Thermax Limited Ball Float Steam Trap is a mechanical steam trap designed for continuous condensate removal while preventing steam loss. It is widely used in process equipment, heat exchangers, and steam lines where condensate load is high and fluctuating.
🔧 Key Features
- Continuous Discharge – removes condensate as it forms (no accumulation)
- Rotary Slide / Float Mechanism – ensures smooth and controlled drainage
- Built-in Thermostatic Air Vent – releases air during startup for faster heating
- No Choking Design – large flow area prevents blockage
- Fusion Welded Ball Float – longer service life and durability
- Handles Variable Loads – performs efficiently under fluctuating condensate loads
⚙️ Working Principle
- Operates on density difference between steam and condensate
- Condensate enters trap → level rises → float lifts and opens valve
- Condensate discharges continuously
- When level drops → valve closes → steam is retained
