Anti-air-binding disc
ST Issue 4
The TD52M is a maintainable thermodynamic steam trap
manufactured in stainless steel specifically designed for relatively
small condensate loads, such as steam mains drainage.
For very low condensate loads, a low capacity version is available.
This version is designated by the letters LC e.g.: TD52MLC.
For those applications where the release of air is a concern an
anti-air-binding disc is available. This version is designated by
the letter A, e.g.: TD52MA and TD52MLCA.
Optional extra
An insulating cover is available to prevent the trap being unduly
influenced by excessive heat loss such as when subjected to low
outside temperatures, wind, rain etc. Not available for the 1" size.
These products fully comply with the requirements of the
European Pressure Equipment Directive 97/23/EC.
These products are available with certification to EN 10204 3.1.
Note: All certification / inspection requirements must be stated at the
time of order placement.
