Industrial Gas Delivery in California: Turnaround Times, Coverage, and Costs

I sat down with Andy Castiglione, President of WestAir, to talk about how WestAir and other industrial gas suppliers deliver gas across California.

The industrial gas supplier with the nearest location to you on Google Maps is often NOT the one that will deliver gas to your business the fastest.

WestAir is an industrial gas supplier serving businesses throughout California, offering next-day delivery as its standard service, plus same-day and after-hours delivery options.

Why Doesn’t Branch Location Decide How Fast Your Gas Arrives?

The nearest branch you see on Google Maps may not run delivery trucks at all.

In the gas and welding industry, production and distribution centers fill cylinders, warehouse hard goods, and dispatch trucks. Retail branches sell over the counter, allowing customers to rent and exchange cylinders for common gases. 

Andy said, “Even though, yes, we have a branch in Escondido, that doesn’t mean that we’re necessarily delivering out of that branch.”

In San Diego, WestAir’s delivery routes run out of its production and distribution center in National City. The Market Street and Escondido locations are retail branches with no trucks of their own.

Why Do Delivery Days Matter More Than Distance?

Delivery days matter more than distance because a customer who runs out between a supplier’s scheduled stops waits for the next one, which can be days or a full week away, however close the supplier’s building is. WestAir runs next-day delivery as its standard and offers same-day and after-hours delivery on top of it.

Some suppliers only run to a given area on set days, such as Monday, Wednesday, and Friday.

“The challenge for the customer with a Monday, Wednesday, Friday schedule is that if they run out of gas on Monday and they miss the Monday delivery, they’re not going to get it Tuesday. They can’t always wait till Wednesday.”

Large national suppliers, including Airgas, assign each area a single weekly delivery day. A leak or a runout the day after the truck passes can mean a week without gas.

Same-day and after-hours delivery aren’t always on the table with those suppliers either. A bar, a lab, or a fabrication shop can sit idle until the regular route comes back around.

A supplier 30 minutes away with one delivery day a week is slower than a supplier hours away that delivers tomorrow. The questions that decide delivery speed are which days the truck runs, how soon after an order it arrives, and whether same-day or after-hours delivery is an option when something goes wrong.

Delivery schedule is one of several things to check when choosing an industrial gas supplier.

How Does WestAir Deliver Anywhere in California?

WestAir reaches every part of California with cylinder delivery routes that run statewide and its own tankers that haul bulk gas straight from production plants to customer tanks. Neither one depends on a nearby storefront.

Cylinder Delivery Routes

Distribution density means enough customers along the same roads that a truck can make many stops in a short day. WestAir has built that density across the state.

“Without that distribution density, it makes it really difficult to run those same-day deliveries or emergency deliveries, or just efficient routes on our next-day delivery routing system.”

A shop in Fresno, Riverside, or Long Beach gets next-day delivery the same way a shop down the street from a WestAir counter does: from a route truck that already runs through its area.

“We don’t have a branch on every corner. But because of that distribution density and customer density that we’ve built up over the last five and a half decades, that’s really enabled us to be very competitive with distribution on all fronts.”

Bulk Gas Deliveries

WestAir’s public-facing branches play no part in bulk supply. Tankers load at the production plant and drive straight to the customer’s tank, so a bulk site in Modesto is supplied the same way as one in National City.

WestAir runs its own drivers, tractors, and trailers, and picks up from two to four plants for a single product. Carbon dioxide (CO₂) is a good example. Refineries capture CO₂ as a byproduct and sell it into food, beverage, and manufacturing markets, so every refinery closure takes supply off the table.

“We lost two really big refineries in California over the last couple of years. And so what we’ve had to do is go out and multisource. We now have the ability to pick up from almost all of them, virtually every single carbon dioxide facility in California.”

WestAir even goes out of state to pick up CO₂ during shortages if necessary, recently running to and from Texas.

What Happens After You Place a Delivery Order?

A WestAir order moves from stocked inventory to a printed order sheet, then grouped with other orders in the same area, onto a truck that afternoon, and out the gate early the next morning.

1. Production keeps minimum and maximum stock levels for every core gas and container size, from 20-cubic-foot cylinders up through six-packs, 15-packs, and 160-, 180-, and 230-liter liquid cylinders.
2. The customer orders by phone, by email, or through WestAir’s online store.
3. Customer service turns the confirmed order into a shipper, the document that tells the warehouse what goes on the truck.
4. The distribution manager sorts shippers into geographic routes throughout the day.
5. Starting around 3 or 4 p.m., loaders put each route’s gases and hard goods on the matching truck.
6. The next morning, each driver checks his load against his shippers and typically leaves between 6 and 6:30 a.m.

WestAir uses Roadnet to plan each route around item counts and how long each stop has historically taken. Samsara tracks each truck’s location and flags safety events like hard braking.

“Not all of our stops take 30 minutes. Some of them could be a quick, easy stop, 10 minutes. Others are a little bit more complex and can take up to 45 minutes or even an hour.”

When Can WestAir Deliver Same Day?

WestAir handles same-day requests for its core gases, including nitrogen, oxygen, argon, and CO₂, by keeping inventory stocked and backup drivers and smaller trucks ready to leave on short notice.

“I don’t know that there’s any supplier out there that can deliver same day or next day for all gases in all areas. However, we can do it for most of the gases.”

Regular routes keep the same driver with the same customers. A same-day call can’t wait for that driver to finish a route an hour away.

“When that driver’s out on the road delivering to a customer in, let’s say, East North County, that’s 45 minutes or an hour away from the production facility in National City. So we need to have other competent drivers that can pick up and go at, let’s say, noon.”

Pickups and small box trucks handle most urgent runs.

“For same days, it’s much better to deliver on a pickup truck or a small Isuzu, because they’re more efficient, they can get into some really tight spaces, and you can just get around the city much easier than those big tractor-trailers.”

Same-day calls come from customers whose production is already shut down.

“The customer can’t weld without argon. So if they don’t have argon, they’re not welding. If they don’t have nitrogen for their food packaging facility, they’re not packaging food.”

How Does Telemetry Get Gas Scheduled Before You Run Out?

WestAir’s Pulsa gas telemetry system reads bulk tanks, microbulk tanks, beverage CO₂ systems, and package gas containers about every 3 minutes, then sends low-level and high-usage alerts so deliveries get booked before a customer runs dry. Older systems gave WestAir one reading per day.

For bulk and microbulk customers, the team aims to schedule deliveries about 72 hours ahead, with 24-hour scheduling available as a standard option.

Liquid cylinders used to rely on float-style gauges that only show empty, a quarter, half, three-quarters, or full. WestAir has standardized on digital gauges that connect to a Pulsa transmitter for remote readings. High-pressure sensors and scales cover single cylinders, six-packs, and 15-packs.

The system also learns each customer’s normal pattern. Here’s an example of steady usage that wouldn’t raise any alarm bells:

But a customer who usually uses 5% of a container per day and suddenly uses 20% triggers a high-usage alert.

“We contact the customer. ‘Hey, checking in. We saw you use 15 or 20% today. You normally use five. Is this high usage or is there something else potentially going on?'”

Sometimes the answer is a leak or a valve left open by accident. A low-level alert lets WestAir schedule the delivery automatically if the customer has agreed to that in advance, or lets the customer decide whether to order now or wait a day or two.

What Do Long-Distance Emergency Deliveries Look Like?

Two deliveries Andy was lining up the day we spoke show how far WestAir will go: bulk argon from San Diego to a medical device manufacturer’s plant in Phoenix, and 20 propane tanks from National City to a restaurant in Temecula.

The Phoenix customer started as a San Diego account and trusted WestAir to install bulk tanks at its Phoenix plant too. When argon supply tightened and that tank dropped close to empty, WestAir was preparing to send a truck from San Diego to Arizona to keep that part of the plant running.

The Temecula restaurant had run out of the 5-gallon propane cylinders that fuel its patio heaters, with a cold, rainy dinner service that night.

“It doesn’t make a lot of sense to do that from a financial perspective. But the fact of the matter is the customer needs those 20 tanks so that they can run their dinner service tonight and service their customers outside on the patio.”

The truck was heading straight from National City to Temecula and back, with the return trip occurring in Friday afternoon traffic.

“Coming home from Temecula could be a three-hour, three-and-a-half-hour drive, but we have the drivers that can do it. So we’re going to make that happen today.”

What Does Industrial Gas Delivery Cost?

Next-day delivery carries only WestAir’s standard delivery fee, while same-day delivery adds $295 and after-hours delivery adds $445.

Customers pay those emergency fees regularly, because even one hour of downtime usually costs more. Andy put typical downtime at $500 to $1,000 an hour, with some equipment costing around $10,000 an hour to sit idle.

Food manufacturers, in particular, experience large losses when CO₂ or nitrogen runs out. Production stops, product spoils, and the store shelf goes to someone else.

“Once you’ve earned shelf space or paid for shelf space, you’ve got it. But if you can’t fill that space with product, in most cases a competitor’s product is going to come in and fill that space, and in a lot of cases it’s very difficult to get that shelf space back.”

Customers who don’t trust their supplier to show up also start ordering early, which means paying for more deliveries per year than they need.

“Distribution’s the biggest expense in our cost to service our customers. When you think about distribution being the biggest expense, you really want to stretch that distribution frequency as much as possible.”

Consistent next-day delivery lets buyers order closer to need, and pairing it with practical steps to prevent gas runouts keeps those orders on schedule.
