Steam trap G3N

  • Suitable for condensate recovery
  • Horizontal installation
  • Automatic venting
  • Option
    – Customized flange

  • Fast commissioning

    Discharges cold air and cold condensate automatically. The membrane capsule deaerator is controlled by the saturation temperature and prevents air and steam congestion.

  • Condensate recovery

    With its high back pressure tolerance, this model is suitable for condensate return.

  • High discharge capacity

    An equalizing valve with two valve openings offers a high flow capacity compared to models with only one opening.

Typical applications

Suitable for use in large heat exchangers in various industries, e.g. in industrial plants, food processing equipment, dyeing/cleaning equipment and air conditioning systems.

● This product uses a balancing valve system with two connections. If the actual amount of condensate is significantly
less than the discharge capacity of the product, there may be a steam leak.

● The diagram of the drain line shows the flow rate for condensate with a temperature of 6 ℃ (43℉) below the saturation temperature.
