WSW is a single-helix sample cooler used to lower the temperature of hot water or steam samples passing on the tube side with cooling water circulating on the shell side. The helical design reduces cooling water requirements and pressure loss; because the coil can be fully drained, draining after maintenance and shutdowns is easy.

Technical data

  • Tube: up to 1200 psi and 650 °F (82 bar, 343 °C).
  • Shell: up to 400 psi and 350 °F (27 bar, 177 °C).
  • Standard coil 1/2 inch 316/316L stainless steel; shell 304/304L or 316/316L.
  • Heat transfer surface 0.23 m².
  • ASME code stamp offered as an option; values vary according to material selection.

The same manufacturer's family also includes options such as TLR, TRW, W9000, TSR, FSR and the double-helix FXR.

Choosing WSW

The single-helix design is simpler and more economical than models such as the double-helix FXR. It is common for power plant samples such as boiler feedwater, steam and condensate, and is also used on sample lines at refineries and chemical plants.

Tetra selects and positions WSW to suit boiler sample lines, together with the cooling water circuit. A leak check is carried out after mounting; spare parts are provided for coil cleaning and renewal of seals and connection elements.
