Spirax-Sarco Engineering TD52L Thermodynamic Steam Trap

Spirax-Sarco’s TD52L Thermodynamic Steam Trap is a compact, all‑stainless‑steel disc-type trap designed for condensate removal in clean steam systems and mains drainage, available in 1/2" and 3/4" NPT connections to fit standard piping. It employs a thermodynamic disc mechanism to discharge condensate with minimal steam loss, and its construction from 316L stainless steel provides durable corrosion resistance in high‑temperature service. The 1/2" and 3/4" configurations support typical steam‑header and condensate‑return applications, helping maintain steam quality and system efficiency. An insulating cover is available to minimize heat loss and thermal drift in sensitive installations. The TD52L family is Spirax‑Sarco’s thermodynamic steam trap line, with the 1/2" and 3/4" variants explicitly documented for this size range. For clean steam mains drainage, Spirax‑Sarco also markets related BTD52L variants built from 316L stainless steel and designed for mains drainage in clean steam systems, reinforcing the material and application profile of the TD52L family.
