Spirax Sarco TD52M, TD52MLC, TD52MA and TD52MLCA Thermodynamic Steam Traps. The TD52M is a serviceable thermodynamic steam trap made of stainless steel and is suitable for use in applications with relatively small condensate loads, such as steam mains. If the condensate load is very small, the low-displacement type (with the letters LC in the name, e.g., TD52MLC) is available. Models with air lock discs (TD52MA and TD52MLCA) are also available for air removal.

options (as in computer software settings)

An optional heat shield is available to prevent excessive heat loss due to low external temperatures (e.g., wind, rain, etc.) Heat shields are not available for 1" caliber products.

Standards and Certificates

The product is fully compliant with the European Pressure Equipment Directive 97/23/EC and can be supplied with a certificate EN 10204 3.1 (if a certificate is required please specify when ordering).
