Features

  • Installation in straight, vertical or horizontal pipe.
  • Minimal headroom is required for mounting
  • Only standard connections are involved for all sizes:NPS 1 (DN 25) water, NPS 3 (DN 80) steam.
  • Few components are required.
  • No atomizing steam or pipeliners, which complicate installation are required.
  • Only 15 feet (4 to 5 meter) of straight run piping downstream.
  • Rapid evaporation of water is achieved to minimize the accumulation of water in the line.
  • Control within 10°F (6°C) of saturation is possible.
  • Repeatable accuracy to ±1% of the range of the temperature controller.
  • Water turndown capacity of 50:1 (typically) or higher is available.
  • Chrome moly body with, stainless steel internals eliminates corrosion problems.
  • Hardened stainless steel nozzles minimize wear.
