Custom CO2 Jets For The Stage And Event Professional: How The Builds Happen

Off-the-shelf equipment covers stages, clubs, and trusses. It does not cover the lid of a $3 million speedboat, the bell of a trumpet, the top of the Matterhorn, or a penthouse where the owner wants CO2 out of the walls and no visible equipment anywhere. Custom CO2 jet fabrication exists for everything on that second list, and CryoFX has spent 15+ years building it: cryogenic effect systems for vehicles, wearables, brand props, theme parks, and rooms no one else would touch.

 

Every project starts with the same three inputs: the budget, the space, and the output the client wants. From there the first decision is whether an off-the-shelf unit can be modified, dissected, or combined to do the job, because that's almost always the budget-friendly route, and only when it can't do we build from the valve up. At the core of every build sits the same architecture as any jet: a rated solenoid valve, a hose, a nozzle, and the electronics that fire them. What changes is everything wrapped around that core.

Vehicles and marine

Speedboats are a CryoFX specialty. On a typical build the tanks live under the front seats and in a side compartment, the hoses route through the hull past the electronics and up to jets that are built into the boat itself, invisible until they fire. We work directly with the speedboat manufacturers during the build so the boat is manufactured around the CO2 system rather than the system bolted on afterward; on a multimillion dollar boat, the last thing the owner wants is equipment marring the lines or mounting holes damaging the gelcoat.

 

Triggering runs through a wireless remote or buttons built into the dash alongside the factory controls, with timers and relays governing how long each activation runs. Systems range from $15,000 to $50,000 depending on equipment, install, and location, sometimes less when the client's own installer handles the labor.

 

Cars split into looks and function. The looks side: race cars with a nitrous-style blow-off at the front, show cars, Lamborghinis, custom semi trucks including the Optimus Prime rig with jets, valves, hoses, and nozzles spraying from several points, and Rose Bowl parade floats. The function side is stranger and real: CO2 plumbed into performance cars to cool the intake air, which lets the engine run more efficiently, the same reason cold air intakes exist.

 

Colder intake air is denser air, more oxygen per stroke, more efficient combustion. And yes, we'd build it again. The most famous automotive build is the official Back to the Future DeLorean replica, which carries a CryoFX-designed CO2 system installed by DNA Fabrication; William Shatner has driven that car, and it has appeared in live performances since.

 

Performer builds and wearables

The CO2 trumpet built for Timmy Trumpet (and two other performers since) fires a plume off the bell on a button press, and the design work went into the recoil: the performer holds the instrument tight so the blast never drives it back into their teeth. Wrist nozzles hide in sleeves. Costume builds fire from the chest. Boot rigs spray at the feet so a performer walks the stage on a cloud from the knees down. Universal's Halloween performers run backpack rigs.

 

A wearable's supply is a CO2 backpack: a 15 or 20 lb tank riding in a frame on the performer's back, adding 40 to 60 lb, triggered by a finger switch, a waist battery pack, or a control sewn into the costume. Runtime is tank math like any jet, and tank swaps between numbers extend it. The safety build is non-negotiable: pads between every nozzle and the skin, hard rules about where hands go during a blast, and a fitting walkthrough with every performer, because liquid CO2 at -78°C doesn't care how good the costume looks.

 

Brand props and activations

The hardest engineering problem we can talk about was the Smirnoff chimney: 2 weeks from order to delivery of a branded chimney with fog funneled up the flue for smoke, lights making the smoke read as fire, CO2 jets firing off the top, and a red scrim wrapping the structure. It toured 5 locations around the country, which meant shipping logistics, a second setup, and different temperature and humidity at every stop; in Las Vegas we added water atomizers firing 30 seconds ahead of the jets to thicken the plume in the dry air, and they helped on some days and did little on humid ones, which is exactly what atmospheric physics predicts.

 

Other brand builds: the Captain Morgan scented cannon, Budweiser bottle blow-offs, Coors Light's thermochromic cans frozen on cue, Nissan NASCAR launches with cars driving through CO2 walls, and a stadium Coke bottle project still in the works. T-shirt launcher and confetti cannon builds fire from the same control systems, biodegradable confetti included, because a brand activation rarely wants only one effect.

 

Theme parks and attractions

Parks ask for effects on rides, and off-the-shelf equipment gets modified before anything gets invented: different nozzles, hardened enclosures, prime valves for instant cues, automation hooks. CryoFX ran volcano and mushroom cloud tests on top of Disneyland's Matterhorn, one of the few companies ever allowed up there, hauling hundred-foot hose runs and 100 lb tanks up from the ground.

 

The Meadowlands drop tower design combined 50 CO2 jets in a ring, strobes winding up like a machine charging, and air cannons punching through the middle to roll a mushroom cloud, designed and tested even though the project never got built. Ride tunnel blasts, animatronic steam, and walk-through effects all run the same playbook: heavy duty cycles, spares on the shelf, and full automation through show control.

 

Hidden and residential installs

The penthouse build is the one we're proudest of aesthetically: a client's building wouldn't allow visible CO2 systems, so the hoses ran inside electrical conduit alongside the building's actual electrical runs, the tanks lived in a storage room, and the jets sat behind motorized covers that open on cue. Sitting in the room, you would never know a CO2 system exists.

 

Compliance didn't bend for the aesthetics: monitoring went in to meet the local fire code, the same as any commercial install, because CO2 in a residence pools at the floor exactly the way it does in a club. Man caves, cigar lounges, and mansions run the same hidden-install playbook.

 

Low fog and water effects

Custom work extends past jets. For Las Vegas running shows we've built chambered low-fog systems with baffles, chilled by CO2 or liquid nitrogen, that pour dense ground-hugging fog; another build sprayed liquid nitrogen into a boiling vat of water to roll thick low fog across an entire stage. For boats we've built water-only fog: an impaction pin nozzle running at 3,000 psi that shatters water into near-mist, the same principle theme parks use, with every component in the path rated for the pressure. Water cannons built around CryoFX CO2 valves round out the dayclub packages. Different media, same engineering discipline.

 

The process

Custom work runs through CryoFX Designs LLC, the design arm, which carries professional liability insurance on every design it stamps, with mechanical, electrical, and plumbing engineers on staff. We hold to each component's rated parameters, and when a spec demands more than a part allows, we find the component that raises the tolerance instead of running anything past its rating.

 

Equipment is built in house and ships modular for simple installation on the client's end, a process proven across dozens of projects. Engagement runs at whatever level fits: recommending off-the-shelf product the client installs, design-only with stamped drawings, build-and-ship, or full project management with permits and operation.

 

Some clients bring us in under NDA as the back-end consultant their end client never meets; others sign three contracts at once, equipment from CryoFX, design from CryoFX Designs, and installation and operation from CryoFX Services. Precise timing and stainless steel where it matters; the rest is listening to what the client actually needs and quoting the version that serves them.

 

The full context for everything above, from valve engineering to tanks, control, safety, and permits, is in the custom CO2 jet fabrication guide section of the pillar. Theatrical cue engineering specifically, prime valves included, has its own page: theatrical CO2 jet. To start a project or see the base equipment the builds grow from, browse custom CO2 jets for sale and send a rental inquiry submission or quote request with your space, budget, and the output you're after.

 

How a project gets quoted

Every quote starts with the same intake, and having the answers ready compresses weeks into days. What's the object or space, with dimensions and photos? What should the effect look like, with a reference video if one exists? How many activations per use, and how long is each? Where can tanks live, and how far is the run? Indoor, outdoor, or vehicle? Who installs, and who operates? And what's the budget band, because the honest number changes the design more than any other input.

 

From those answers CryoFX quotes one of three shapes: a modified off-the-shelf build (fastest and cheapest), a custom assembly around stock valves and controls, or a ground-up fabrication with engineering hours attached. Budget bands run from a few thousand dollars for a single modified prop, through $15,000 to $50,000 for vehicle and marine systems, into six figures for venue-scale custom installations.

 

Timeline follows shape. Modified equipment ships in days to a couple of weeks, next day service exists for emergencies at rush pricing, custom assemblies run weeks, and engineered builds run months plus the permit path where one applies. The Smirnoff chimney's 2-week sprint is the record we quote against, and we tell clients honestly that it was a sprint.

 

Renting a custom build

Not every custom effect needs to be owned. Brand activations that tour for a season, one-off TV moments, and proof-of-concept runs all rent: CryoFX builds the effect, operates it or ships it with instructions, and takes it back when the campaign ends.

 

A rental inquiry submission with the event dates, the space, and the desired effect starts that conversation, and for productions weighing rent against build, the crossover lands around the third deployment, the same 2-to-3 rule that governs standard jet rentals. Global special effects campaigns that hit multiple cities get the Smirnoff treatment: a second setup built alongside the first so one ships while the other shows.

 

What we need from you to start

Send five things and the first design call is productive instead of exploratory: photos or drawings of the object or space with dimensions; a reference video of the effect you're imagining (a phone clip of another show works); the activation profile (how many firings, how long, how often); the tank possibilities (where cylinders can live and how far the run is); and the budget band you're working inside. NDA first when the project needs one; a large share of CryoFX custom work lives under NDAs, and the process is built for it.

 

Why the valve rules custom work too

Every exotic build above obeys the same physics as a stage jet. The valve must be rated for liquid CO2 at 850 to 900 psi with seals that survive -78°C, the hose must be built for the service, and the fittings must match, because a trumpet build and a drop tower build fail the same way when a component is wrong: loudly, and at the worst moment.

 

That's why custom quotes from CryoFX sometimes come back higher than a fabricator who found cheaper internal components; solenoid valve quality is invisible in the render and decisive in the third month of shows. It's also why we support other builders: fabricators and effects fabrication shops buy rated valves, cryogenic hose, and control modules from us for their own projects, with our engineers a phone call behind the parts. Creative CO2 work is welcome in this industry from every corner. Under-rated parts are how the whole industry loses venues, so the parts are where we hold the line.

 

Every finished build also ships with its documentation: cut sheets for the components, operating instructions written for the client's actual crew, and the maintenance schedule matched to the duty cycle the system was designed for. Custom equipment without documentation is a future orphan, and CryoFX has inherited enough orphans from other builders' projects to refuse to create one. When the system needs service years later, the file exists, the parts are stocked, and the engineer who drew it still answers the phone.

 

Frequently asked questions

Can CryoFX build a custom CO2 jet for a vehicle? Yes: speedboats built with the boat manufacturer, race cars, show cars, semi trucks, parade floats, and the official Back to the Future DeLorean replica. Systems hide inside the vehicle, trigger from the dash or a wireless remote, and run $15,000 to $50,000 for marine builds.

 

How much does a custom CO2 jet cost? Modified off-the-shelf equipment starts near catalogue pricing. Full custom systems run from a few thousand dollars for a single prop to $15,000 to $50,000 for vehicle systems, and into six and seven figures for venue and park installations.

 

How long does a custom build take? The Smirnoff chimney went from order to a touring build in 2 weeks. Typical custom projects run weeks to months depending on engineering, and permitted installations add the permit timeline on top.

 

Can CO2 jets be built into costumes? Yes: wrist nozzles, chest rigs, boot rigs, and instrument builds, supplied by a 15 or 20 lb backpack tank and triggered from a finger switch or waist pack, with padding between every nozzle and the performer's skin.

 

Can CO2 jets be hidden in a building? Yes. The CryoFX penthouse build ran hoses through electrical conduit, tanks in a storage room, and jets behind motorized covers, with CO2 monitoring installed to meet local fire code. No one in the room can tell the system exists.

 

Does CryoFX engineer the installation? Yes. CryoFX Designs LLC produces stamped mechanical, electrical, and plumbing drawings with engineers on staff and professional liability insurance behind every design, and CryoFX Services installs and operates where the client wants the whole project handled end to end.

 

Can you modify a jet I already own? Usually. Nozzles, enclosures, control interfaces, and mounting can all be adapted, and modifying existing equipment is the first option we price because it's the budget-friendly one.
