Watson McDaniel Thermostatic Clean Steam Trap FDA500 Series

The Watson McDaniel FDA500-12 Thermostatic Clean Steam Trap is a specialized device designed for use in clean steam systems, commonly found in industries with stringent hygiene requirements, such as pharmaceuticals and food processing. This steam trap is engineered to efficiently remove condensate from steam lines while preventing the escape of live steam, which is crucial for maintaining energy efficiency and system performance.   

The FDA500-12 is a thermostatic trap, meaning it operates based on temperature differences. It contains a stainless steel thermal element that expands and contracts in response to temperature changes. When condensate and air are present, which are cooler than steam, the trap is open, allowing them to discharge. When hot steam reaches the trap, the element expands, causing the trap to close and prevent steam loss.   

These traps are specifically designed for "clean steam" applications, indicating that they are constructed from materials and with surface finishes that minimize contamination and comply with industry standards for hygiene. They are often used as drip traps on steam piping and for drainage in Clean-In-Place (CIP) and Sterilize-In-Place (SIP) systems, which are essential for maintaining the sterility of equipment and processes.
