Description
Spirax Sarco TD52M, TD52MLC, TD52MA and TD52MLCA thermodynamic steam traps are stainless steel units designed for applications with relatively low condensate loads, such as steam mains. TD52M is a repairable thermodynamic steam trap. For very low condensate loads, the low-capacity version can be selected; these models include the letters LC, such as TD52MLC. Versions with an anti-air-binding disc, TD52MA and TD52MLCA, are also available for air removal.
Options
An insulating cover is available to minimize excessive heat loss caused by low external temperatures, such as wind and rain. Insulating covers are not available for 1” sizes.
Standards and Certificates
This product fully complies with European Pressure Equipment Directive 97/23/EC. An EN 10204 3.1 certificate is available; specify this requirement when ordering.
