DongSung Energy Saving Solution

Dong Sung ES is a high-technology company that pursues the highest efficiency of all thermal facilities using steam as a heat source and specializes in design, manufacturing, construction, and commissioning of plant facilities and electronic energy saving projects.

DST Steam Trap & Optimum Power Control Device For Motors (OPC-M) is the only brand in Korea and abroad to become a global energy saving specialist.

DST Steam Trap

The product is a valve that removes condensate generated in steam pipes by depriving steam of latent heat due to thermal change, and is designed to perfectly discharge condensate without having any mechanical moving parts by utilizing the density difference between steam and condensate through the body and nozzle composed of a venturi type structure, saving more than 20% of steam than mechanical steam traps(Volumetric, Bucket, Disk, ThermoDyne type), and is certified as an energy innovation product by the Ministry of Trade, Industry and Energy.

Optimum Power Control Device For Motors (OPC-M)

During operation of facilities such as fans, blowers, pumps, compressors, various presses, hydraulics, and pump-jacks of onshore oil wells, it continuously/repeatedly detects the incoming current that fluctuates in proportion to the axial load applied to the drive motor in real time at a rate of 1 in 100,000, calculates the motor speed to exert the optimal torque for the corresponding load, and transmits the corresponding signal (4~20mA) to the inverter (VFD) to keep the power factor always above 0. It is certified by the Ministry of Trade, Industry and Energy as an energy innovation product that reduces active power by 15~50% or more while maintaining a power factor of 0.98 or higher.

Major Business

DST Steam Trap

(Condensate Removal Device Customized Steam Trap)

  • 01

    Unlike mechanical steam traps (Ballhurt, Bucket, Disk, ThermoDyne type), no mechanical action is required to activate the trap, so there is no physical impact on the steam line and no water hammering.

  • 02

    Semi-permanent use as parts are made of 100% stainless steel, unlike conventional traps, there are no mechanical moving parts in the trap body, so there are no parts to fail or wear out. Debris in steam piping is removed by opening the body's integral strainer and brow valve.

  • 03

    Venturi nozzle actively responds to the amount of condensate and intelligently discharges condensate, eliminating live steam leakage from steam lines and saving water and electricity, and proving to be a superior air trap for pneumatic applications.

Optimum Power Control Device For Motors

(OPC-M)

  • The OPC-M is a current transformer (CT) that very quickly detects changes in current and regresses the appropriate torque calculated according to the power law, without the need for separate sensors and transducers for each step of the motor load fluctuation, so that only the minimum force to maintain the process is sent to each process step, realizing significant electrical energy savings of 15-50% on average.
