Threaded, compact, low to medium flow <3°F (2°C) subcool operation

Two piece threaded body, balanced port, low to medium flow thermostatic sanitary steam trap with 3°F subcool operation, vertical inlet and outlet threaded connections (for tube fitting applications). Designed specifically for biopharmaceutical and food & beverage pilot and trail scale skid equipment manufacturers for pure steam SIP and loop drainage applications

  • Up and downstream process vessel: small to medium sized vessels with validated SIP drain lines
  • Up and downstream process tubing: validated SIP drainage
  • Filters: small filter validated SIP drainage
  • Clean steam distribution drainage
Features & Benefits
  • Low subcooling operation reduces probability of temperature validation faults and resultant SIP delays
  • Lay-in dimension allows drop in replacement of higher subcool competitive traps
  • Compact construction of solid 316L barstock
  • Simple, three piece design with fewer components, cracks and crevices than competitive designs
  • Self-draining when installed vertically (body outlet side down) either vertical or horizontal connections
