Product details
Automatic advanced programmable Liquid Nitrogen Microdosing system

Any #900 series model will work without modifications as:

  • autonomous stand-alone unit;
  • direct remote controlled unit;
  • will operate on any voltage between 12-24 V (AC or DC);
  • or with our power supply (115V or 230 V);
