Thermodynamic Traps are typically used on drip or tracing applications in chemical processing plants, petroleum refineries, paper mills, and other processing industries that use higher pressure steam.

Watson McDaniel offers many different models with features including in-line repairability, high pressures up to 900 psig and Integral In-line Strainers for protection against dirt and contamination.

Float & Thermostatic Traps are primarily used for process application due to their high-capacity and excellent air venting capabilities.

Watson McDaniel offers the most complex range of F& T Traps in the industry. Trap bodies materials are available in Cast-Iron, Ductile Iron and Cast-Steel with operating pressures up to 450 psig. Both in-line and parallel pipe connections are available. Inverted Bucket

Inverted Bucket Traps (IB) are an economical solution for drip and tracing service and are excellent for higher pressure steam application.

Watson McDaniel Inverted Bucket Traps body materials are available in Stainless Steel and Cast-Iron. All internals are made of hardened Stainless-Steel for extended service life.
