“In the past, we would try to predict when we were close to having the liquid filled. The operator might walk away to perform another task, and the liquid could possibly overfill. Now, we have savings on two fronts—we don’t have to monitor as closely, saving labor; and we’re preventing overfills.”

- Robert Parsons, Operations Manager for Holston Gases, Inc.

Liquid Fill Systems

For High Pressure Cylinder Pumped Filling and Liquid Can Pressure Filling Applications 

Weldcoa’s automated liquid fill stations save time (labor hours) and money (minimize losses) by taking the fill process out of the cylinder filler’s hands. The single or 2 gas liquid cylinder filling system provides a means of automatically filling portable cryogenic containers with liquid Oxygen, Nitrogen or Argon.  A digital scale is used to measure the weight of product and to automatically shut off product flow when the desired fill weight is achieved.  The system is designed to fill via pressure transfill from the supply tank.

Weldcoa Automated Liquid Fill System Minimizes: 

  • Product losses by not overfilling the liquid cylinders. For every minute of overfilling, it equates to a loss of 30% of the capacity of the container.
  • Issues with Department of Weight and Measures about the overfull containers
  • Labor costs, as the filler is able to perform other functions while the system is filling the liquid cylinders.

Features & Benefits

  • Turnkey/modular design
  • Interpiped & interconnected
  • Durable construction
  • Quick & easy connections
  • Safer filling
  • Increased productivity
  • Frees operators to multi-task
  • Delivered as self contained, turn key units that are ready to operate once the existing gas lines have been connected to them
  • All units are built and tested at Weldcoa prior to shipping to the customer work site. This assures that the unit is fully operational upon receipt. 
  • Made in the USA

 

Automated Systems (Most Popular and Recommended)

With the automated system, the filler will put the liquid cylinder on a pit or low profile drum scale, connect fill the hose, input the fill weight desired and push the “Start” button. At the point the filler can walk away to do another function as the liquid supply valve will open, fill the liquid cylinder to the selected weight and then close the liquid supply valve. Once the liquid cylinder is full, a visual (light) and audible (horn) alarm will notify the filler that the process is complete. He can walk back to close the liquid and vent valves on the liquid cylinder so that not all of the pressure is blown out through the vent valve.

“With the automation in the new fill plant in Tulsa, variability is removed and process repeatability is ensured.”

Harry Fite, Owner of Gas & Supply's Oklahoma Facility

“Automation has enabled us to save labor, increase quality and consistency, and preserve raw materials.”

Robert Parsons, Plant Manager for Holston Gases facility in Knoxville, TN

“We’ve grown tremendously on the back of the new Weldcoa fill plant.”

Dave Messina, Plant Supervisor for WestAir Gases & Equipment's National City, CA facility

“Our sales guys are much more confident in our product than ever before. We’re ready to take on other gases now, which we have been outsourcing. The new Weldcoa equipment gives us the confidence to consider moving that work inhouse. There’s a lot of room to grow.”

Curt Towne, Owner of Depke Welding Supplies in Danville, IL
