CO2 delivery in Denver

CO2 delivery in Denver runs out of our depot at 11185 E 51st Ave in northeast Denver. Micro bulk CO2 goes into an enclosed high-pressure system at your site through an external fill box, and the telemetry included on every account tells us when your level is coming down.

Your CO2 supplier in Denver for one site or eight

Multi-location operators feel the cost of venting and cylinder handling once per site. When Allen Partlow, District Manager for Denny's, looked at our system for eight Denver-area restaurants, he put the reason in one line:

What intrigued me about this system is that we will be saving money while reducing our carbon footprint at our 8 locations. It just made CENTS!

Micro bulk CO2 delivery in Denver against a cryogenic tank

Most of the Denver sites we assess are on one of two setups: a bank of high-pressure cylinders someone swaps by hand, or a low-pressure cryogenic vessel that vents gas between fills. On a conventional bulk system that venting is approximately 30% or more of the CO2 you paid for.

Our High-Pressure Micro Bulk CO2 System is enclosed, with the patented DS6000 diverter valve inside it, so what is delivered is what reaches your taps or your grow room. Each site on a multi-site account is measured on its own usage, because two stores under one brand rarely pour the same volume.

The 2025 Denver Building and Fire Code and a new CO2 install

Denver adopted the 2025 Denver Building and Fire Code on June 13, 2025, built on the 2024 International Codes, and it took effect December 31, 2025. CO2 systems fall under the fire code's compressed gas chapter, which asks indoor CO2 storage areas for either ventilation or a gas detection system.

We specify the install and its CO2 monitoring in Denver together, so the sensor layout is part of the plan your inspector sees rather than something added after a failed walkthrough.

Common questions

Boulder, Golden, Evergreen and Idaho Springs are all on our Colorado territory list, between about 22 and 43 road miles from the depot. Give us the address and we will confirm the route before you commit to anything.

No. Denver is split between our Northern and Southern Colorado territories by ZIP code, which is why the quote form asks for yours: it sends you straight to the Territory Sales Manager who covers your site.
