Ensuring Chart's Success... "Cooler By Design" - Chart's principal focus is the design and fabrication of cryogenic equipment; so you can see where we get our tagline from, right? Well, yes and no - see, we think the stuff we design and build is pretty cool too. What's more, we're problem solvers. Customers don't come to Chart with an equipment specification, they come to Chart with a challenge. That's where you come in, because someone has to figure it out, all the way from conceptual design to installation and commissioning of equipment at site. The applications we service are pretty diverse (and cool) too - from solutions for launching rockets into space; to providing low carbon energy for vehicles, industries and even entire communities; to the preservation of critical human and animal tissue. Pop into a well-known fast food outlet and it'll likely be Chart equipment supplying your carbonated beverage. If nitro coffee or nitro ice cream is your thing - well, that's Chart...
