During an interview on an upcoming episode of Ratermann's Podcast, High-Pressure, George was asked, "If you could tell your customers one thing, what would it be?" Press play to find out what it is.

Cryogenic tanks are typically filled from the top using the blow down method. The blow down method is when the pressure of the tank is reduced by blowing out the head pressure of the tank in order to fill it. Blowing down a tank wastes product and in turn costs money. Top filling also requires taking the tank offline or to not be used while it is being filled because the tank cant keep pressure, which causes the customer using the tank to shut down and stop their operation during filling. However, the Arctic Fox tank enables the user to simultaneously fill from the top and bottom, eliminating the need to use the less efficient blow down method. The bottom fill method keeps the pressure up, allowing the user to keep the machine online and keeping their operation running since the Arctic Fox maintains the required pump pressure to keep operating. The top and bottom filling method does not require a tank to be blown down and therefore prevents loss of product during the filling process. For customers such as laser cutting facilities that use nitrogen gas in their machines to cut metal products, the Arctic Fox tank is invaluable as it permits operations and production to flow smoothly throughout the entire filling process. Because the top and bottom fill capability maintains the necessary pressure levels during the filling process, the user can continue production without halting the use of the gas. This ensures a seamless filling period for the customer unlike the process required by other tanks that rely on the top fill method. Additionally, the Arctic Fox tank features different hookup options. This flexibility allows multiple types of trucks to connect to fill the tank, including conventional micro bulk-trucks with a standard cryogenic hose and those with an inch and a half bulk hose. This way, users aren’t limited in what kind of trucks they can use to fill their tanks. Throughout the entire process, the operator has complete control over the pump pressure of the Arctic Fox tank. With top and bottom filling capability, filling is much faster than any other method. And users can complete rapid tank fills without the use of specialized proprietary pumping equipment. The arctic fox tank was designed for filling to be a seamless and efficient process. With the Ratermann Manufacturing Arctic Fox Tank you will be able to maximize both production and efficiency while minimizing costs to your customer’s company. The Arctic Fox tank’s top and bottom fill feature and duel blow down vents ushers in a smarter, faster & overall more efficient way to fill tanks allowing companies to fill tanks faster and make more deliveries per day.

When You Need a Vaporizer: Short answer: If the demand of gas needed (also known as flow rate) is higher than the output of a liquid cylinder the pressure and flow rate will drop. Adding a vaporizer to the liquid cylinder increases the flow rate of the liquid cylinder while keeping the same pressure. Meaning the flow rate and pressure stays constant. Longer explanation: A typical 160 liter cryogenic liquid container with a medium pressure has an output of about 350 standard cubic feet per hour of liquid nitrogen. After the first hour of operating, the output of the dewar starts to slow because the container becomes cold. Warm air allows the container to convert the liquid into gas quickly. The lack of warm air drops the output of the tank after the 1st hour of use. If more than 350 standard cubic feet of liquid nitrogen is needed per hour, the dewar would be unable to keep up with the demand. The tank would start to over draw the vaporization. A scenario such as this is when you would use a vaporizer. A vaporizer allows you to continue to convert liquid into gas for long periods of time as oppose to being limited to a liquid cylinders standard output. If customers need a higher flow rate, a vaporizer can be attached to the liquid container and will generate a higher flow rate for a longer period of time.
