Spirax-Sarco 54530C Trap

The Spirax-Sarco 54530C is a high-performance TD52 thermodynamic steam trap designed specifically for the rigorous demands of industrial steam main drainage, tracer lines, and process equipment. Constructed from high-grade stainless steel, this 1/2" NPT trap features a hardened disc and seating surfaces to resist the erosive effects of superheated steam and high-velocity condensate. The TD52-1/2" excels in applications where waterhammer or freezing conditions are a factor, providing a reliable discharge cycle that ensures condensate is removed near steam temperature. With a maximum operating pressure of 600 psig and a maximum temperature rating of 800°F, this thermodynamic disc trap is a versatile choice for field technicians. Its compact inline horizontal piping footprint allows for easy installation in tight manifold configurations, while the maintainable design ensures the disc can be inspected or replaced without disturbing existing pipework. For freeze-proof installations, this unit should be installed vertically with a downward discharge to prevent condensate retention during shutdown.

• Rugged Stainless Steel Construction: Resists corrosion and high-temperature oxidation in aggressive steam environments.
• High Back-Pressure Tolerance: Operates efficiently with back pressures reaching up to 80% of inlet pressure, preventing trap lock-up in pressurized return lines.
• Hardened Disc and Seat: Extends service life by minimizing wire-drawing and seat erosion common in high-pressure steam tracing.
• Vertical Orientation Option: When installed vertically, the trap becomes self-draining, making it ideal for outdoor applications prone to sub-zero temperatures.
• Maintainable Internal Parts: The disc and seat can be lapped or replaced in the field, reducing downtime and total cost of ownership.

Is the Spirax-Sarco TD52 susceptible to air binding?
While thermodynamic traps can occasionally air bind during startup, the TD52 design minimizes this by utilizing a high-velocity blast action. For systems with extreme air venting requirements, ensuring proper upstream straining is critical.

What is the minimum pressure required for operation?
The Spirax-Sarco 54530C requires a minimum operating pressure of 3.5 psig to maintain the differential necessary for the disc to cycle correctly.

Can I use this trap on superheated steam lines?
Yes, the all-stainless construction and hardened internals are specifically rated for superheat applications where traditional thermostatic or mechanical traps might fail.
