Thermodynamic Steam Traps (TD)
Spirax Sarco patented the thermodynamic design in 1953; today it is still the world''s most versatile and reliable trap. The compact design features a mirror-polished, differentially hardened disc and seat for long life and a tight seal. They also provide excellent resistance to water hammer.

TD 3
The TD 3 is a thermodynamic steam trap with an inbuilt strainer and a full stainless steel construction, best suited for header and mainline drains and drop legs. This trap with srewed ends is suitable upto 36 barg and with socket weldeble ends is suitable upto 42 barg and 425°C.

TD 62 (Flanged Connections) ASTM Body
The TD 62 is a maintainable high pressure thermodynamic steam trap with an integral strainer specifically designed for steam main line drainage applications upto 62 bar g. An aluminium insulating cover is fitted as a standard to prevent the trap being unduly infuenced by excessive heat loss when subjected to low ambient temperatures, wind or rain.
Max. allowable pressure is 103 barg
Max. allowable temperature is 525°C

TD 62 (Flanged Connections) DIN Body
The TD 62 is a maintainable high pressure thermodynamic steam trap with an integral strainer specifically designed for mains drainage applications upto 62 bar g. An aluminium insulating cover is fitted as a standard to prevent the trap being unduly infuenced by excessive heat loss when subjected to low ambient temperatures, wind or rain. Body and cover castings are produced by a TÜV approved foundry.
Max. allowable pressure is 100 barg
Max. allowable temperature is 525°C

UTD 30 L and UTD 30 LA (Thermodynamic Steam Trap & Swivel Connector)
The UTD 30 L and UTD 30 LA are thermodynamic steam traps complete with pipeline connector for either horizontal or vertical installation with easy removal from the line without breaking the pipework.
UTD 30 LA has special air venting disc to eliminate air binding.

Balanced Pressure Thermostatic Trap (BPT 21/AV 21)
The BPT 21/AV 21 is a Thermostatic Steam Trap/Air Vent fitted with an inbuilt flat strainer screen having 0.8 mm diameter perforations. These traps are mainly used on Steam Tracing application. When installed at the end of steam line or process equipment, BPT traps functions as steam trap and when installed on steam line header, it acts as air vent.
