Spirax Sarco TD52,54531C Thermodynamic Steam Trap

Spirax Sarco TD52, 3/4 in FNPT Thermodynamic Steam Trap (54531C), is a stainless steel, Cool Blue heavy‑duty unit with ENP finish and an integral insulated cap that helps minimize heat loss in exposed steam lines. As a disc‑type thermodynamic trap, it discharges condensate very close to steam temperature and automatically cycles to maintain efficient steam distribution across heat exchangers, piping headers, boilers, and other process equipment, reducing energy waste without compromising condensate removal. Rated up to 800°F (427°C) at all operating pressures and up to 600 psi (41 bar), it features 3/4 in FNPT connections for straightforward installation in compact layouts and stainless steel internals designed for high‑temperature service. Common applications include steam lines, heat exchangers, boilers, and other high‑temperature steam systems in industries such as chemical processing, refining, food and beverage, and pharmaceuticals where reliable condensate drainage is critical.
