High Efficiency Liquid Nitrogen Dosing

High Efficiency Liquid Nitrogen Dosing

Product Used: SMAC LCA31 series linear

Problem: Traditionally the pneumatic cylinder is used to control a valve for liquid nitrogen dosing. The pneumatic cylinder gave an impact on the valve when closing. The liquid nitrogen is cooling the valve seal to temperatures that metal seals are like glass and become brittle. Impact damages the closing seal so that they need replacement every half year. This shuts down the line for quite a long time.

Solution: SMAC actuators’ highly repeatable & positioning coupled with high speed allows the user to more precisely & repeatedly control the dosing amount. SMAC actuators also allow for easy change over for different dosing requirements. Another advantage is the life of the SMAC actuators as well as the extended life of the dosing valve, as SMAC’s unique Soft-Land function prevents damage to the valve when closing. This will result in increasing valve’s life time. These features will increase uptime and increase profitability for end user.

SMAC Advantages

  • Better force control of liquid nitrogen dose for cost savings on the amount of liquid nitrogen used. (Soft-Land)
  • SMAC actuator is fully programmable in force, speed, and position.
  • SMAC actuator can be easily set-up and make quick change via GUI to run a different motion profile for the liquid nitrogen valve. No mechanical adjustments required.
  • Programmable motion profile dosing valve.
  • Dosing valve stroke verification.
  • SMAC actuator’s exceptional long-life over 100,000,000 cycles increasing uptime and lowering replacement cost.
