Two Orifice Float Trap TOFT

The term “TOFT” stands for “Two Orifice Float Trap.” This type of steam trap is a mechanical device used in steam systems to discharge condensate, air, and other non-condensable gases while preventing the escape of steam. The “Two Orifice” design refers to the presence of two orifices in the trap.

Here are some key features and functions of the Two Orifice Float Trap (TOFT):

  1. Float Mechanism: The trap contains a float mechanism, usually a ball float, which rises and falls with the level of condensate in the trap. As condensate accumulates, the float rises, opening the orifices and allowing condensate to be discharged.

  2. Two Orifices: The trap has two orifices—one for condensate discharge and another for the removal of air and other non-condensable gases. The dual orifice design helps in efficient removal of both condensate and gases.

  3. Air Venting: The trap is designed to efficiently vent air and non-condensable gases, preventing their accumulation in the steam system. This is crucial for maintaining optimal heat transfer and preventing damage to equipment.

  4. Continuous Operation: The TOFT is a continuous-type trap, meaning it operates continuously, discharging condensate as it is formed. This is in contrast to intermittent traps that operate in cycles.

  5. Suitable for Various Applications: TOFTs are commonly used in steam systems where efficient removal of condensate and air is essential. They are suitable for applications with varying loads and steam pressures.

  6. Low Maintenance: Float traps, in general, are known for their durability and low maintenance requirements. Regular inspection and testing are recommended to ensure proper operation.

  7. Efficient Energy Transfer: Proper condensate removal is crucial for efficient heat transfer in steam systems. Float traps help maintain the temperature of the steam and ensure optimal energy transfer.

When considering the installation of a Two Orifice Float Trap (TOFT) or any steam trap, it is important to consider factors such as system pressure, condensate load, and the specific requirements of the application. Always refer to the manufacturer’s documentation and guidelines for accurate information on a particular TOFT model.
