What is the difference between TD62LM and TD62M?

The TD62LM is designed for smaller condensate loads with a minimum operating pressure of 8 bar g and maximum 50% backpressure tolerance. The TD62M handles higher backpressure (up to 80%) and operates from as low as 1.4 bar g, making it suitable for a broader range of applications.

Can the TD62LM be installed in any orientation?

The trap is preferably installed in horizontal pipelines with the insulating cover facing upward. However, it can be fitted in other positions if required. After 24 hours of service, cover nuts should be checked for tightness.

What spare parts are available for these steam traps?

Available spares include insulating cover, cover studs and nuts set, seat and disc assembly, strainer screen (100 mesh), and gasket sets. Spares should be ordered by description along with trap size and type.

Is third-party certification available?

Yes, these traps are available with material certification to EN 10204 3.1. Certification requirements must be specified at the time of order placement.

What strainer mesh size is provided?

The integral strainer uses a 100-mesh 316L stainless steel screen, providing effective protection against particulate contamination in steam lines.

Overview

The Spirax Sarco TD62LM and TD62M are high-pressure thermodynamic steam traps engineered for mains drainage applications in demanding industrial environments. These traps feature a replaceable seat design that simplifies maintenance and extends service life, along with an integral strainer to protect against debris ingress.

The TD62LM variant is optimised for relatively small condensate loads on superheated steam and mains drainage lines. It comes standard with an aluminium insulating cover that prevents operational issues caused by excessive heat loss in low ambient temperatures, wind, or rain. Both models are rated for pressures up to 62 bar g and comply with the European Pressure Equipment Directive (PED).

Constructed from robust steel castings with Charpy-tested bodies meeting 27J @ -30°C, these steam traps deliver reliable condensate removal while minimising steam loss across a wide range of operating conditions.
