    ThermoDyne® A3N

    A3N/AF3N

    Long life, best quality
    The most versatile thermodynamic steam trap

    Durability

    TLV products are designed from the outset to help minimize life cycle cost. The A3N is quality-made for durability, ensuring long-term stable operation.

    Versatility

    With its high discharge capacity and pressure range up to 1.6 MPaG, the A3N can be used on a wide range of applications ‒ from steam mains to light processes.

    Reliability

    The predecessor of the A3N, the A3, appeared in 1958. Ten times more durable than conventional traps in its day, this line is a longtime bestseller.

    Benefits and Features

    Energy Conservation

    Steam loss due to adverse weather conditions such as rain and wind is drastically reduced by the steam jacketed pressure chamber.

    Improved Productivity (Bimetal Type Automatic Air Venting Feature)

    Automatic air venting reduces start-up time, greatly improving productivity. Additionally, reductions in steam loss, fuel consumption and labor can be achieved by eliminating the need for manual blowdown at start-up.

    Easy Maintenance

    The valve disc and valve seat can easily be replaced by removing the outer and inner covers. Traps can be repaired in-line without the need for specialized equipment.

    Application Areas

    Applications that do not require precise temperature control.
