Thermostatic:
A Thermostatic Trap contains a heavy-duty, industrial-purpose welded stainless steel thermal element designed to control condensate discharge by sensing the temperature difference between steam and cooler condensate. Body materials available are Cast Iron, Stainless and Alloy Steels with thermal element designs available for pressures up to 650 psig. The WPN Series Bi-metallic design will handle presssures up to 2,260 psig.
Typical Applications: Extremely versatile and energy efficient, these traps are suitable for a wide range of applications. Thermal element designs are suitable for applications ranging from general service drip and tracing applications to small-to-medium batch style processes. Bi-metal designs can be used in high pressure, superheated drip applications or in lower pressure tracing applications.
Advantages: Self-draining when mounted vertically to prevent freezing, single model operates over wide pressure range in contrast to mechanical traps, small and compact with similar capacities to larger mechanical traps (F&Ts & IBs), superior air venting capabilities, welded stainless steel thermal element and bi-metal elements are extremely rugged, moderate discharge due to reduced flash steam, choose between fail-open or fail-closed bellows.
Other Factors to Consider: Some condensate back-up can be expected, thermal element
design not recommended for superheated applications.
