Thermodynamic Steam Traps

Description

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.
