Custom Eco-CO₂ System
A liquid CO₂ transport trailer is a pressure-rated mobile unit designed to store and deliver bulk liquid carbon dioxide for on-site cylinder refilling. Equipped with a cryogenic tank, high-pressure pump, and filling manifolds, it allows operators to top off multiple CO₂ cylinders without transporting them back to a central facility. This mobile refilling capability reduces turnaround time, lowers costs, and ensures a reliable CO₂ supply for industries such as food and beverage, welding, and fire suppression.
We automatically log and track all cylinders that you have with us so that you can focus on what matters most: your bar, restaurant or brewery.
WestAir has partnered with Pulsa Sensors to offer our customers state-of-the-art telemetry to enhance service and better inform our deliveries. Keep tabs on your current CO₂ usage from anywhere, giving you peace of mind for when you are running low on the gas you need to run your bar or restaurant. Critical warnings detect leaks faster, and work efficiently to save you money with fewer deliveries and “run outs”.
