Cryotech International, has a complete line of liquid nitrogen (LN2) dosing equipment for inerting/nitrogen flushing and pressurization applications. Using advanced vacuum technology for cryogenic transfer, Cryotech engineers designed an ultra-efficient, double walled, vacuum insulated nitrogen dosing unit. Typically installed after the filler and before the capper, the Cryotech doser dispenses a measured amount of LN2. Once the LN2 (-320F/-195C) is introduced into the container, it immediately picks up heat and turns into gaseous nitrogen, expanding 700 times in the process. When trapped inside the container, the gaseous nitrogen creates pressure and adds rigidity to the container. For inerting applications, the rapidly expanding nitrogen is allowed to escape before the product is sealed, flushing oxygen out of the container. The patented CryoDoser series is designed for high speed lines up to 2000 containers per minute. Customers can choose from an Allen Bradley (AB1500) or Siemens controller (S7200). The CryoDoser series also offers Direct Inject head that can dose (pulse) up to 1800 containers per minute before changing to steady stream. The UltraDoser series is Cryotech's line of general purpose injection units. Ideal for production plants on a budget, the UltraDoser AB1500 and S7200 are for medium to high speed production lines. The UltraDoser SC350 is our low speed unit, designed for line speeds up to 350 cpm. The IntroDoser is an introductory level injection unit ideal for limited production runs, semi-automatic or manual fill lines and developmental work. The Inerter™  delivers a large volume of LN2 required for food inerting applications such as peanuts, potato chips and snacks. The SoftDose upgrade option offers a gentle delivery that allows the LN2 to sit on top of the hot product, eliminating the violent reaction typically associated with nitrogen dosing of hot-fill applications. Cryotech provides value-added insight to your production operations. Our project managers have a wealth of practical LN2 dosing knowledge from hot-fill PET bottles, aluminum tubes, and glass to plastic conversions. We also have experience with a wide variety of products from water to wine; peanuts to pie filling; and ice cream to iced tea.   All systems are easy to operate and can be integrated into new or existing lines.
