Reducing Waste & Cost One Drop at a Time

One part of liquid nitrogen (LN2) warms and expands into 700 parts of gaseous nitrogen at ambient temperature. Chart's automated dosers dispense a precisely measured dose of LN2 into each container prior to sealing. The trapped LN2 vaporizes, creating pressure, and adding rigidity to the container – allowing for a thinner container wall.

Chart helps customers achieve their environmental commitments.

The annual amount of plastic that will be saved using Chart’s LN2 MicroDose™ Technology in four filling operations in Brazil is close to 1.6 million pounds (726 thousand kg). That’s about the same weight as 24 adult humpback whales.

SoftDose™ Technology

Places or sprays liquid nitrogen on the surface of the product rather than penetrating the product surface, essentially eliminating any product splash and delivering consistent container pressure. Can be tailored to a specific product, package or application.

RemoteDose™ Web Technology

Permits control access to via the customer's intranet enabling engineers to view the process, create and load recipes and trouble-shoot from a desktop PC, laptop or mobile device. Actions that previously required multiple staff for a large-sized machine or long-distance application are easily accomplished with significantly fewer operators.

MicroDose™ Technology

Developed in response to market demands to precisely dose liquid nitrogen into ultra light weight packaging to comply with tight container pressure specifications. Incorporates multiple sensors to detect variables such as filling line speed and bottle presence, that the system uses for fine tune elctronic adjustments.

Support Service & After Sales

Let Chart develop and improve your product packaging. Send us your samples and we'll provide preliminary data and feedback to help you evaluate the benefits of liquid nitrogen dosing We provide installation, supervision, start up, commissioning, and training, along with 24/7 Technical Support.

Complete Turnkey Solution

From initial design to a complete after-sales package, we work closely with our customers to ensure that the complete system is engineered and built in accordance with their requirements and always operating at peak efficiency.

  1. Storage: complete range of LN2 liquid cylinders, MicroBulk systems and bulk tanks.
  2. Withdrawal: a vacuum insulated valve has the benefit of extremely low heat leak for minimum gas boil-off and eliminates unsafe ice build-up.
  3. Vacuum Insulated Pipe: the foundation for heat loss efficiency and long-term integrity.
  4. Phase Separator: provides extremely high-quality, low pressure LN2 on demand resulting in a continuous supply of unsaturated LN2.
