Modern servo technology delivers finer control, reduced downtime, and enhanced adaptability for various beverage applications.

Woburn, MA – Vacuum Barrier Corporation, a leader in the design, engineering, and fabrication of liquid nitrogen dosing and piping systems, will showcase its newest high-speed liquid nitrogen dosing system at Pack Expo 2025 in Las Vegas, September 29–October 1. At Booth W-3856, the company will feature its NITRODOSE® G3 SERVODOSER®, a breakthrough solution that combines advanced servo control with innovative heater block designs to deliver unmatched dosing precision, flexibility, and reliability.

The NITRODOSE® G3 SERVODOSER® is engineered for fast, precise delivery of low-pressure liquid nitrogen in beverage applications. It can handle up to 2,000 containers per minute (CPM), and allows manufacturers to adjust the flow rate during both discrete and continuous dispensing without mechanical nozzle changes, significantly reducing downtime during production changeovers.

Enhanced Servo Technology for Greater Precision
Modern servo technology incorporated into the dosers allows for much finer control of LN? dosing. Operators can achieve precise metering in both steady-stream and single-dose operation through simple parameter adjustments on the control panel. Quick “on the fly” adjustments reduce or eliminate the need for mechanical nozzle changes, minimizing downtime and improving operational efficiency. Servo actuators are robust and reliable, providing billions of cycles without required maintenance, saving both time and replacement costs.

Innovative Heater Block Designs for Versatility
Recent developments in heater block design enable servo technology to be fully realized across a wide array of beverage products and container formats. Certain heater blocks incorporate additional nitrogen gas purging capabilities to limit freeze-ups during or after washdown cycles, or when processing hot-filled products in humid conditions. Others are optimized for discrete or steady streaming into very low headspace containers, such as high-speed canning lines, where maintaining tight pressure tolerances is critical.

Smart, Operator-Friendly Design
The NITRODOSE® G3 SERVODOSER® is equipped with a seven-inch color touchscreen for intuitive operation, capable of delivering dosing durations as short as 4 milliseconds with an accuracy of approximately +/-1% of dose weight. It also features Clean-in-Place (CIP) protection, with an automatic cover that prevents moisture from entering the dosing head during washdowns, eliminating potential freeze-ups. The nozzle design withstands high-pressure washdowns and harsh chemical cleaning, ensuring long-term durability.

“The NITRODOSE® G3 SERVODOSER® represents a significant advancement in liquid nitrogen dosing technology,” said Jim Fallon, International Sales Manager at Vacuum Barrier Corporation. “By combining precise servo control, versatile heater block options, and robust mechanical design, we’re giving beverage manufacturers a system that adapts to their production needs with maximum uptime and efficiency.”
