Welding with shielding gases produces cleaner and faster welds, especially when using CO2 for welding deep, thick material. Welders improve their welding penetration performance and avoid potential porosity problems with an inline gas heater.


Medical professionals rely on stable CO2 flow rates they get from inline heaters for controlled respiratory stimulation before and after anesthesia, inflating body cavities during surgery, and Cryotherapy—tissue freezing to remove moles, warts, and skin tags.


Microbreweries use a constant flow of C02 for finishing fizzy flavor, transferring beer, canning and bottling, and purging tanks for the next round. When business is brewing, a constant stream of gas is flowing with a reliable inline gas heater.

Food Packaging

The demand for fresh ideas in food packing with less plastic containers continues. Growers are preserving the quality of their specialty foods with Modified Atmospheric Packaging. It’s a way to capture packaging margins, enhance their brand, and work directly with retailers.


A greenhouse is no place for a freeze-up. Growers know the value of CO2 for accelerating the growth rates of plants—a healthy crop is a profitable crop. An inline gas heater provides a steady flow of CO2 to increase photosynthesis for a constant supply of plant food.


Winemakers use CO2 to keep business flowing and use an inline gas heater to warm gas lines. From adding “sparkle” to their sparkling to “spritzing” their spritzers, they’re able to bottle beverages with the same ease as blanketing tanks and barrels.

More industries rely on Calco for smoother flowing gas.
